Airspace closures through the Middle East grounded and diverted flights on Saturday as Iran launched drones toward Israel.

United Airlines, which resumed service to Tel Aviv early last month after suspending Israel flights after the Hamas attacks in October, called off its Newark to Tel Aviv flight on Saturday after Israel closed its airspace. Jordan and Iraq had also closed their airspace, according to Jordanian state-owned media news outlet Al Mamlaka.

“We are closely monitoring the situation and will make decisions on upcoming flights with a focus on the safety of our customers and crews,” United said in a statement. The carrier is the only U.S. airline to have resumed service to Israel since October. Delta was scheduled to restart flights to Tel Aviv on June. 7. American Airlines has not resumed Israel service.

United also canceled its flight from Washington Dulles International Airport to Amman, Jordan on Saturday night, “due to unrest in the Middle East.”

It was not clear when flights would resume.

Flight-tracking site Flightradar24 said multiple flights bound for Tel Aviv and Amman had diverted on Saturday.

Airlines also canceled service scheduled for Sunday. Israel’s El Al cancelled more than 20 Sunday flights. Two El Al flights headed for Israel from Thailand diverted to Bangkok. The carrier told passengers not to come to the airport until notified.

Emirates Airline canceled its Dubai-Amman flight scheduled for Sunday. Air France’s Israel service was canceled for Sunday and British Airways canceled its two flights to Tel Aviv on Sunday and scrubbed a flight to Amman. Lufthansa also canceled its service to Israel.

A tire fell off a United Airlines plane taking off from San Francisco International Airport Thursday morning and landed in a nearby parking lot, damaging several vehicles, officials said.

The tire from United Flight 35, which later arrived safely in Los Angeles, landed in an employee parking lot, SFO spokesman Doug Yakel said. No injuries were reported.

The runway was briefly closed to allow crews to clear debris, Yakel said. There was no further impact to airport operations.

Flight 35 was headed for Osaka, Japan, before being diverted to Los Angeles International Airport, where it landed safely.

The plane, a Boeing 777-200, has six tires on each of its two main landing gear struts, according to the airline. It is designed to land with missing or damaged tires.

The plane was carrying a total of 249 people – 235 customers, 10 flight attendants and 4 pilots, according to the airline.

United said customers boarded a new plane at LAX to Osaka.

“We’re grateful to our pilots and flight attendants for their professionalism in managing this situation. We’re also grateful to our teams on the ground who were waiting with a tug to move the aircraft soon after it landed and to our teams in the airport who assisted customers upon their arrival,” United said in a statement. “We will work with customers as well as with the owners of the damaged vehicles in SFO to ensure their needs are addressed.”

The Federal Aviation Administration on Saturday ordered a temporary grounding of dozens of Boeing 737 Max 9 aircraft for inspections, a day after a piece of the aircraft blew out in the middle of an Alaska Airlines flight.

Images and video of Alaska Airlines Flight 1282 that were shared on social media showed a gaping hole on the side of the plane and passengers using oxygen masks before it returned to Portland shortly after taking off for Ontario, California, on Friday afternoon.

The FAA’s emergency airworthiness directive will affect about 171 planes worldwide and applies to U.S. airlines and carriers operating in U.S. territory, the agency said.

No serious injuries were reported on the flight, according to federal safety officials. There were 171 passengers and six crewmembers on board, Alaska Air said.

“Safety will continue to drive our decision-making as we assist the NTSB’s investigation into Alaska Airlines Flight 1282,” FAA Administrator Mike Whitaker said in a statement.

Large-scale groundings of aircraft by the FAA or other aviation authorities are rare. The FAA has heavily scrutinized the Boeing 737 Max since two fatal crashes grounded the jetliner worldwide almost five years ago. Two other models of the Max, the smallest and largest version, have not yet been cleared by the agency to enter commercial service.

The section of the fuselage missing appeared to correspond to an exit not used by Alaska Airlines, or other carriers that don’t have high-density seating configurations, and was plugged.

The incident was described as “an explosive decompression at the window exit,” said Sara Nelson, president of the Association of Flight Attendants-CWA, the labor union that represents Alaska’s cabin crew and flight attendants at United, Spirit and other carriers.

Anthony Brickhouse, a professor of aerospace safety at Embry-Riddle Aeronautical University, said such an incident is extremely rare.

“Rapid decompression is a serious matter,” he said. “To see a gaping hole in an aircraft is not something we typically see. In aviation safety, we would call this a structural failure.”

The incident is also a reminder to keep your seatbelt fastened when seated, he added.

“I always advise people on a commercial aircraft, keep your seatbelt on regardless of what the light says,” Brickhouse said.

A passenger didn’t appear to be seated in the seat next to the panel.

Before the FAA issued its directive, Alaska Airlines earlier said it would ground its fleet of Boeing 737 Max 9 planes. Alaska said on Saturday afternoon that of the 65 Boeing 737 Max 9 planes in its fleet, 18 “had in-depth and thorough plug door inspections performed as part of a recent heavy maintenance visit.”

Those planes were returned to service on Saturday, Alaska said.

More than 140 flights, about 14% of Alaska’s schedule, were canceled on Saturday, according to FlightAware.

The National Transportation Safety Board sent a team to Portland on Saturday to investigate the incident.

United Airlines, the largest operator of the planes in the U.S., had prepared to ground dozens of its Boeing 737 Max 9 aircraft for inspections, CNBC reported earlier.

United has 79 Boeing 737 Max 9 aircraft in its fleet but just over 30 of them have already “received the necessary inspection that is required by the FAA,” the airline said. The inspections were expected to cause about 60 flight cancellations on Saturday, United said.

The FAA said the inspections will take between four and eight hours per plane.

The Boeing 737 Max 9 is a larger version of Boeing’s best-selling jetliner, the 737 Max 8. Max planes were grounded worldwide in 2019 after two fatal crashes within about five months of one another. The U.S. lifted its flight ban on the jets in late 2020 after software and training updates.

The Boeing 737 Max 9 has an emergency exit door cut behind the wings for use in dense seating cabin configurations, like those used by budget airlines, according to Flightradar24.

“The doors are not activated on Alaska Airlines aircraft and are permanently ‘plugged,'” Flightradar24 said.

Boeing didn’t comment beyond its statement when asked about the sealed emergency exit door. Spirit AeroSystems, which makes the fuselages for the planes, referred CNBC to Boeing when asked about the incident.

“Safety is our top priority and we deeply regret the impact this event has had on our customers and their passengers,” Boeing said in a statement on Saturday. “We agree with and fully support the FAA’s decision to require immediate inspections of 737-9 airplanes with the same configuration as the affected airplane.”

The company said it is supporting the NTSB’s investigation.

There are 215 Boeing 737 Max 9 planes in service worldwide, according to aviation-data firm Cirium. In addition to United and Alaska Air, other operators include Aeromexico, Turkish Airlines, Icelandair and Panama’s Copa Airlines.

Southwest Airlines and American Airlines operate the smaller 737 Max 8.

Late last year, Boeing urged airlines to inspect aircraft for a “possible” loose bolt in the rudder control system, the latest in a series of manufacturing flaws on Boeing jets that have prompted additional inspections, and slowed deliveries of the jets.

In air travel, minutes matter.

A few moments could be the difference between making and missing a connection for passengers — and could avoid delays that ripple across the schedule for airlines. Saved time could even lead to big savings for carriers as they scramble to get a handle on costs.

Major airlines are rolling out strategies that executives say could translate to lower costs and more efficient operations, even if the time savings on paper look negligible.

Some of these tools will be put to the test during what’s expected to be a busy holiday season, a year after a meltdown that stranded thousands of passengers at the end of 2022. Many of the improvements are being made behind the scenes.

American Airlines last year started using new technology to assign flight gates at Dallas/Fort Worth International Airport, the world’s second-busiest airport and American’s biggest hub, where it operates out of 135 regional and mainline gates.

The new procedures, replacing a near-manual hours-long process, allowed the airline to avoid many of its planes crossing from the east side to the west side of the sprawling airport, saving an average of two minutes of taxi time per flight, adding up to about 11 hours saved a day, American said.

The technology helped reduce taxi time by 20% and halved gate changes and conflicts, according to the carrier.

“It took the nightly process of gating the airline from four hours to about 10 minutes,” said American COO David Seymour.

The so-called Smart Gating program has been expanded to Charlotte Douglas International Airport, Miami International Airport, Ronald Reagan Washington National Airport and most recently, in May, Chicago’s O’Hare International Airport, Seymour said, adding that the airline is considering using the technology in Phoenix as well.

The gating technology in other airports aims to avoid gate congestion that could delay flights from departing or parking upon arrival.

“If you try to do late-minute gate changes as planes arrive … you could get out of sync with your caterers and fuelers,” Seymour said, adding that the tools American built are tailored for each airport’s issues.

In the first eight months of the year, 76.4% of American’s flights arrived within 15 minutes of their scheduled arrival times, which the Transportation Department considers on time. That performance ranks American third among major U.S. carriers for on-time arrivals, an improvement from fifth place during the same time period last year.

Short taxi times and other improvements can help airlines save fuel, one of airlines’ biggest costs. American said its new gating program saves it 1.4 million gallons of fuel a year, equal to about $4 million based on fuel prices at major U.S. airports this month.

American isn’t alone in looking to shave off a few minutes.

United Airlines last month launched a new boarding procedure for economy class, accommodating window-seat passengers first followed by the middle and then the aisle. United told staff the changes could save it up to two minutes per flight.

Southwest Airlines has also experimented this year with ways to expedite boarding, trying everything from better signage to music on the jet bridge to keep travelers moving. For years, Delta Air Lines flight attendants and gate agents have used digital messages during boarding, to send alerts for issues such as full overhead bins.

Discount carrier Frontier Airlines is aiming to speed up boarding and deplaning through pathways outside jet bridges. The company has started using stairs directly onto and off the plane, taking advantage of a second door on the carrier’s Airbus jets.

“If you want to board an airplane faster, use two [gates] instead of one,” CEO Barry Biffle said.

The Denver-based airline is in talks with several airports to increase that type of boarding, without a traditional jet bridge. Biffle estimated that the carrier could have a third of its flights using stairways for boarding and deplaning in about two years.

Biffle said that could save as much as 10 minutes off the turn time, the amount of time it takes for a plane to park, deplane, reload and depart.

Robert Mann, who has worked at several airlines and is president of aviation consulting firm RW Mann & Co., said how airlines use the time savings will be key. Baking it back into the schedule could mean airlines wouldn’t have to block off as much time for a flight, he said.

“When you actually plan shorter flight times, you have more airplanes available,” he said.

An American Airlines spokesman said that as the airline becomes more efficient, in future schedules, it could allot less time for each flight, increasing the airline’s ability to add more flights.

Don’t miss these stories from CNBC PRO:

Travelers are flocking to airport lounges in search of complimentary food, drinks and perhaps most importantly, a chance to relax away from the hordes of travelers at the gate. The problem: plenty of other travelers are too.

Armed with high-end rewards credit cards and fresh from years of big spending, more and more travelers are gaining access to airport lounges, turning what were once small, exclusive spaces for an elite few into a must-have stop for millions of passengers.

The trend has posed both an opportunity and a challenge for airlines and credit card companies as they market luxury to the masses. The spaces have to be both exclusive and attainable for enough people.

For top frequent flyers and certain credit card holders, standard airline lounge access is complimentary or discounted. Individual annual lounge memberships run between $650 and $850 for the major U.S. carriers, which have raised prices in recent years.

Delta Air Lines Sky Club lounges — and the credit cards that grant entry to them — became so popular that customers complained about the long lines and crowds at many locations. The airline in response curbed access for employees, instituted time limits and in its most controversial move yet, announced annual limits on visits for many credit card holders — even stripping some credit cards of access altogether.

But many customers complained about those changes, too, saying they were too strict. This week, Delta walked back some of the changes, highlighting how hard it has become to strike the right balance between exclusivity and access.

“Any wait is too long, and we are doing everything we can to minimize that,” Delta’s chief customer experience officer, Allison Ausband, told CNBC last summer at the opening of a new, larger Sky Club at John F. Kennedy International Airport in New York.

She said the lounges are “not a profit center for Delta by any means” but are an “investment that we’re making in the premium experience for our customers.”

Delta executives have said that revenue growth for its premium products like business class has outpaced that of main cabin economy.

Delta, United Airlines and American Airlines are racing to build more lounges and spaces and larger ones to fit high demand.

They have also divided, or are planning to divide their lounges into different tiers. United, for example, opened a grab-and-go express club at its hub at Denver International Airport last year, for travelers making tight connections, which the carrier said could free up space in more full-service lounges.

The carrier separately operates a network of Polaris lounges for travelers booked in its highest cabin class, usually on long-haul international routes.

Delta is in the process of building a network of highest-tier lounges aimed at travelers in its Delta One suites and other top customers. Those spaces are slated to begin opening next year, starting with one at Kennedy Airport, followed by Los Angeles and Boston.

Credit card issuers such as JPMorgan Chase, Capital One and American Express are also opening new spaces in airports, eager to attract and retain high-spending customers.

“Customers reward companies that take care of them and that are on their side and and that create amazing experiences,” said Jenn Scheurich, head of travel at Capital One.

The company has opened clubs at Washington Dulles International Airport and Dallas/Fort Worth International Airport and plans to open one at Denver International Airport early next month, with other projects at New York’s LaGuardia Airport and Ronald Reagan Washington National Airport.

Capital One Venture X cardholders pay a $395 annual fee for that card, which comes with unlimited access to the company’s lounges, as well as access for two guests. The general public can get in for $65 a visit.

Chase opened its first Chase Sapphire lounge in Hong Kong in 2022 and its first in the U.S., at Boston Logan International Airport, in May, featuring a tap room and massage chairs. It’s planning to open other lounges at LaGuardia Airport, Washington Dulles, Las Vegas, Philadelphia, Phoenix, and San Diego.

Those lounges are open to customers with Chase Sapphire Reserve cards, which have a $550 annual fee, along with two guests.

A brief nationwide ground stop for United Airlines flights was lifted Tuesday, the Federal Aviation Administration said.

“Earlier today a software update caused a widespread slowdown in United’s technology systems,” United said in a statement.

“We briefly held aircraft at their origin airports and resumed normal operations around 12:45 p.m. CT.,” the airline said. “Our teams are working to get customers to their destinations as soon as possible.”

The ground stop lasted slightly more than an hour, and did not affect in aircraft already in flight when it was called. United is investigating the cause of the slowdown, but does not believe it is a cybersecurity issue.

United’s stock price closed more than 2% lower on Tuesday.

American And Jet Blue One will stop selling seats on flights next Friday, two months after a federal judge ruled that the Northeast airline partnership violated antitrust laws.

The judge ordered the airlines to end their partnership of more than two years, which allowed them to share passengers and revenue, and coordinate schedules in the northeastern United States. Delta And united In busy airports serving New York and Boston.

The Department of Justice, six states, and the District of Columbia sued to block this partnership, winning their case on May 20.

““We are disappointed to end popular benefits such as codeshare and mutual loyalty benefits,” Dave Fintzen, JetBlue’s vice president of Northeast Alliance, said in a statement. With the recent court ruling and the termination of the NEA, we have to go down I say in short order.”

JetBlue said last week it would not appeal the ruling, so it could focus instead on its $3.8 billion acquisition. Spirit Airlines, a deal also challenged by the DOJ, though JetBlue said it did not agree with the judge’s ruling on the Northeast alliance. However, America said it still plans to appeal the ruling on the Northeast Alliance.

Earlier this week, airline websites still offered flight options on each other’s airlines during the year-end holidays, but those sales will only last through July 20.

Both airlines said they will work with customers who have existing reservations so that their plans are not disrupted.

“This is only the first step in the truce process that will take place over the coming months,” American said in a statement. “We will continue to work with the JetBlue team to ensure that customers with existing codeshare reservations can travel smoothly without disrupting their travel plans.”

Thursday is also the last day customers can use their American AAdvantage frequent flyer miles to book flights on JetBlue.

United Airlines“The plan to refurbish cabins on its aging narrowbody planes is behind schedule due to supply chain strains,” the carrier told CNBC this week. Upgrades include larger luxury cabins, seatback entertainment screens throughout the aircraft, Bluetooth capabilities and other amenities.

The Chicago-based airline previously expected to retrofit 100 of its narrowbody planes with the new interiors by the end of the year, but now expects 60 to be completed by then, a spokeswoman said.

“The reality is supply challenges across the board be that as it may [inflight entertainment] Systems, chips, seats and many other things are more challenging than they’ve ever been in our business,” Andrew Nosella, United’s chief commercial officer, said on an earnings call last week.

United unveiled the overhauled cabins in June 2021 following an order for 270 new Boeing and Airbus’ narrowbody jets, in an effort to refresh its brand as airlines compete for passengers in the travel boom, especially big spenders.

United also said it expects to have more premium seats for sale per outbound flight than any other North American airline by 2026 as travelers compete for what could be elusive upgrades and the ranks of elite travelers with piles of frequent flyer points swell.

United’s Nocella said last week that the carrier will have multiple production lines to refresh the interiors of its narrow-body jets this summer, helping to pick up speed.

The company expects that one in three aircraft in its narrow-body fleet, including new aircraft, will have had an in-house upgrade by the end of the year.

“It’s going to take a little longer than we originally expected,” he said. He added that the United Airbus A319 was recently modified and is scheduled to fly soon.

The airline has targeted 2025 to complete the narrowbody upgrades, but it’s unclear if United will meet that target.

Separately, United said all of its wide-body aircraft will be equipped with premium economy seats and Polaris seats, the carrier’s first class on international and other long-haul flights, by August.

Other airlines such as Jet Blue And Delta Airlines They have also added amenities on their aircraft in recent years, upgrading their first-class classes, installing new seats and adding some services, including free Wi-Fi.

Delta executives said revenue growth for premium seats such as business class or premium economy has outpaced sales from the standard coach.

“We’re seeing a high degree of stickiness with these products,” Delta president Glenn Hounstein said on the company’s quarterly call earlier this month. “So once you start flying in those cabins, you don’t tend to go back.”

The Federal Aviation Administration lifted a nationwide grounding of planes Wednesday morning after a technology outage delayed thousands of flights, but airlines warned the problem would continue to disrupt travel throughout the day.

The FAA said early Wednesday that domestic flights would be grounded until at least 9 a.m. ET while the agency works to restore the Air Mission Notification System, which is responsible for sending messages to all pilots, such as runway closures, hazards and other information.

All flights currently in the air were safe to land, the agency said.

More than 4,300 U.S. flights were delayed as of 9:10 a.m. ET, according to flight tracker FlightAware, and residual delays could last hours from backup after the ground shutdown is lifted.

Delta, United and Southwest said schedule adjustments are likely Wednesday. Airlines regularly delay their schedules so that airports are not overwhelmed by planes without parking space.

More than 700 US flights were canceled on Wednesday. More than 23,000 flights are scheduled to, from and within the US, according to aviation data company Cirium.

“This technology issue is causing significant operational delays across the National Airspace System,” said Airlines for America, an industry group that represents major U.S. carriers, including Delta, American, United, Southwest and other.

By 8:15 a.m. ET, flights had resumed from Newark Liberty International Airport and Hartsfield-Jackson Atlanta International Airport, the FAA said.

The White House said Transportation Secretary Pete Buttigieg informed President Joe Biden of the outage.

“There is no evidence of a cyberattack at this point, but the president has directed the DOT to conduct a full investigation into the cause,” White House press secretary Karin Jean-Pierre said said in a tweet.

The incident comes just weeks after bad weather during the busy holiday period caused mass flight disruptions in the US and days later, more than 15,000 Southwest flights were canceled after the carrier abandoned all schedule changes.

Southwest is preparing to cancel flights on Wednesday to avoid further disruption, Casey Murray, president of the Southwest Airlines Pilots Association, told CNBC.

Shares of Southwest were about 1 percent lower in premarket trading Wednesday. Shares of other major airlines were little changed.

This is breaking news. Please check back for updates.

Southwest Airlines canceled more than 70% of its flights on Monday, while flight disruptions stemming from severe winter weather eased at other carriers, prompting concern from the US Department of Transportation.

As of Monday evening, Southwest had already cleared 60% of its flights for the next day.

Airlines have canceled more than 17,000 U.S. flights since Wednesday, according to FlightAware, as the storms brought snow, ice, high winds and bitter cold to the country, derailing air travel from coast to coast. These conditions slowed down the crews as they faced harsh conditions at the airfields.

Southwest said Monday it expects “further changes with already reduced flight levels as we approach the upcoming New Year’s holiday period.”

Carriers are likely to detail the cost of the outages when they report results next month, if not sooner. Southwest Airlines had huge problems. Executives cited unexpected fog in San Diego, staff shortages at a fuel supplier in Denver and in-house technology among additional challenges.

“USDOT is concerned about Southwest Airlines’ disproportionate and unacceptable cancellation and delay rates and failure to properly assist customers who experience cancellations or delays,” the Department of Transportation said late Monday. “When more information becomes available, the department will carefully examine whether the cancellations were controlled and whether Southwest followed its customer service plan and any other relevant DOT rules.”

Delta Air Lines, American Airlines, United Airlines, JetBlue Airways and Alaska Airlines were among the carriers affected by the weather. But other airlines had a percentage of canceled flights on Monday.

Southwest’s woes continued Monday as other carriers stabilized. The carrier canceled more than 2,800 flights, 70% of its schedule, and another 670 were delayed. By comparison, Delta canceled 9% of its mainline flights on Monday, United 5% and American less than 1%, with 12 flights canceled.

More than 3,200 US flights were canceled Monday and nearly 5,000 were delayed. Southwest canceled many flights proactively in an effort to stabilize operations, Chief Operating Officer Andrew Watterson told staff.

From Wednesday through Sunday, nearly a third of Southwest flights were canceled and two-thirds were delayed, according to FlightAware data.

The airline apologized to employees for the chaos that left many scrambling to get hold of crew scheduling services, making it difficult to reassign or make other changes or get hotel rooms.

Southwest also offered extra pay to flight attendants working during the holidays.

Southwest CEO Bob Jordan said in an announcement to staff Monday that it could take several more days to fix the airline’s operations.

“Part of what we’re suffering from is a lack of tools,” Jordan said in a message to staff Sunday. “We talked an awful lot about modernizing the operation and the need for it. And team planning is one of the places we need to invest. We need to be able to produce solutions faster.”

Some pilots and flight attendants have been forced to sleep at airports because they have been unable to find hotel rooms, their unions said.

Teams complained about being blocked and having to wait on hold with scheduling services. “Our customers struggled with this, just like our thousands of flight attendants. These are problems you can’t solve with vacation pay; it’s time and quality of life we’ll never get back,” Lynn Montgomery, president of the Transport Workers Union of America Local 556, said in a statement.

The pilots’ and flight attendants’ unions are in contract negotiations with the company.

Airlines often cancel flights proactively during bad weather to avoid planes, crews and customers being out of place, problems that can make recovery from a storm more difficult.

Carriers also planned smaller schedules for Christmas Eve and Christmas compared to the days leading up to the holidays, making it difficult for them to book passengers on other flights, and bookings increased. An American Airlines spokesman said “the vast majority of our customers affected by the cancellations have been able to be readmitted.”

Delta “is seeing a steady recovery in our operations and we expect improvements to continue over the next several hours,” a spokesman said Monday.

The extreme cold and high winds slowed ground operations at dozens of airports. More than half of flights on US-based airlines arrived late Thursday through Saturday, with delays averaging 81 minutes, according to FlightAware.

“Temperatures dropped so low that our equipment and infrastructure were affected, from frozen ventilation systems and fuel lines to broken towbars,” United Airlines said in a message to pilots on Saturday. “The pilots encountered frozen locks when attempting to re-enter the jet bridge after performing a go-around.”

The FAA said it had to evacuate its downtown tower at United Newark Liberty International Airport in New Jersey due to a leak on Saturday.

Meanwhile, JetBlue offered flight attendants triple pay to take trips on Christmas Eve due to staff shortages.

An American Airlines spokesman said “the vast majority of our customers affected by the cancellations have been able to be readmitted.”

Delta “is seeing a steady recovery in our operations and we expect improvements to continue over the next several hours,” a spokesman said Monday.

However, passengers also encountered delayed luggage.

Bill Weaver, 41, said he, his wife and five children were driving from Wichita, Kansas to Dallas Fort Worth International Airport for a Friday flight to Cancun after their connecting flight to the American Airlines hub was canceled. The American Airlines flight to Cancun arrived on time, but their luggage didn’t arrive in Cancun until Monday and didn’t arrive at their hotel until mid-morning, so they had to spend hundreds of dollars to buy clothes and other essentials at their hotel.

Weaver, who works in software sales, said he traveled frequently.

“I’m used to missing bags and things happening, but this is the worst I’ve ever seen,” he said.
