Unexpected tech outages have been impacting airlines and airports across the world. Major hotel brands have also reported outages. Here’s what to know if you’re planning to travel this weekend.
Widespread IT problems are impacting global travel. It’s believed the issue stems, at least in part, from a software update issued by software company CrowdStrike on Microsoft Windows operating systems.
The CEO of CrowdStrike said in a statement obtained by CNN early Friday that the IT issue causing a global outage had been identified and a fix had been deployed.
Meanwhile, Microsoft said the “underlying cause” that led to the global outage “has been fixed,” but added that residual impact is still affecting some services.
Airports, airlines and travelers across the globe continue to navigate the fall-out.
Which airlines and airports are impacted?
US-based carriers American Airlines, United Airlines, Delta Air Lines, Allegiant Airlines, SunCountry and Frontier Airlines all reported issues on Friday. American Airlines has since said it has “safely reestablished” operations, while United resumed “some flights” Friday morning.
Delta Air Lines resumed some flight departures but additional delays and cancellations were expected Friday.
The Federal Aviation Administration (FAA) said in a statement early Friday that was “closely monitoring a technical issue impacting IT systems at U.S. airlines,” adding that “several airlines have requested FAA assistance with ground stops until the issue is resolved.”
The agency provided an update later in the day: “Currently FAA operations are not impacted by the global IT issue. We continue to monitor the situation closely.” The agency also said the IT issue “could continue to affect flights this weekend.”
Ryanair, Air France and Turkish Airlines also reported issues, while KLM Royal Dutch Airlines said the outages are “making flight handling impossible.” AirAsia said its “core reservation and check-in system” have been impacted by the tech issues.
Cirium, an aviation analytics company, said there were around 110,000 scheduled commercial flights Friday. By 3 p.m. ET, Cirium said there were more than 5,000 flights canceled globally.
Many airports across the globe also logged tech-related issues. Dubai Airport reported issues on Friday morning, but the airport said in a post on X that normal operations had resumed.
Passenger William Sikora III told CNN Friday morning that the situation at Philadelphia International Airport is “absolutely insane right now” in the wake of the disruption.
Airports across the US cautioned travelers to expect delays and to check their flight status before going to the airport.
In Europe, London’s Gatwick Airport said it is “affected by the global Microsoft issues” and that passengers may experience delays checking in and going through security. London’s Heathrow Airport said it was working with “airport colleagues to minimize the impact” and advised passengers to check with their airlines for the latest flight information. Berlin Airport said it is experiencing delays to check-in, while Amsterdam’s Schiphol Airport stated the impact on its airport is “being mapped.”
Scotland’s Edinburgh Airport said the outages mean “wait times are longer than usual at the airport.” Spain’s airport authority, AENA, which supervises airports in Madrid, Barcelona and others across the country, said the tech issues “could cause delays” and that its staff are working to solve the problems.
Airports and airlines in Asia and Latin America were also reporting disruptions caused by the IT outage.
This is not an exhaustive list, so it’s best to check the status of any airports you’ll be transiting through this weekend before you travel.
This is also a fast-moving situation heading into Friday night and the weekend, so if you’re planning on flying, it’s best to keep tabs on your chosen airline’s social media channels, apps and website for up-to-date information. Check your flight status before you head to the airport, if you can.
Travel will likely take a while to get back on track, even once the outage is sorted. The stoppage of flights means that thousands of aircraft have been grounded around the world and could be stuck in the wrong airports.
Crews have limits on their working hours, so staffing challenges cascade along with flight delays.
Getting schedules back on track is a complicated process that can take several days to fully iron out. The best course of action is to monitor your airline for announcements and to know your rights as a consumer.
First off, if you can, check the status of your flight before you leave for the airport. It’s better to find out your flight is canceled from the comfort of home or a hotel room and make new arrangements from there, if at all possible.
If you’re already at the airport, head to the airline help desk. While you’re standing in line, it’s worth phoning the airline help number and trying to contact the company via social media or email. If you are a member of an airline executive club and have access to a special phone number, now is the time to use it.
If it looks like the airline won’t be able to put you on a flight until the following day, ask for a hotel room or hotel voucher. There are fewer consumer protections for situations outside of airlines’ control, but it’s worth requesting. And if your airline seems to be impacted, but another airline is still operable – ask about flying with other carriers.
“When flights are canceled, many airlines have the option of putting you on another carrier’s flight because they have interline agreements,” Lousson Smith, product operations specialist at Going.com, told CNN Travel in our guide to flight cancellations, which you can read here.
“This means, for example, if Delta is having service interruptions but American is running a flight to your destination, you may be able to get on that flight.”
If you can plausibly take a train rather than fly – for instance, if you’re in the UK heading to mainland Europe – it could be worth checking last-minute ticket availability.
That depends on where you’re flying to and from – in the US, for example, passengers have the right to a refund for canceled flights, but additional compensation or accommodation for delays or cancellations outside of carriers’ control is up to each airline.
On flights to and from EU countries, the laws are different. If your airport of origin is within the EU or if you’re arriving to the EU on an EU airline, you’re entitled to a refund for delays longer than five hours and additional compensation for some shorter delays.
Wherever you’re traveling, it’s worth familiarizing yourself with the airline terms and conditions associated with your booking.
And if you have travel insurance, look up your rights there too.
That all depends on the type of ticket you have, the airline you’re flying with and whether you have travel insurance (which is always a good idea). Insurance covers missed departures and connections – if your flight is delayed, your company may be able to help change your travel plans, though it’s unlikely that they’ll refund you if your flight is not affected but you no longer want to travel.
Check your airline to see if it’s offering passengers the chance to cancel or change dates. As the situation spirals and airlines reroute passengers on canceled flights, the flexibility may increase. At the time of writing, American Airlines is offering free changes for those due to fly on July 19 through eight major hubs (there are caveats as to rebooking dates).
British Airways said it has increased flexibility for customers flying shorthaul routes over the weekend.
Delta, United and American all issued waivers for impacted customers
Marriott International says some of its hotel systems have been impacted by the ongoing global IT outage.
“We are actively working with our vendors to resolve issues that have impacted certain hotel systems. We apologize for any inconvenience that guests may experience,” the company said in a statement to CNN Friday afternoon.
CNN has reached out to Hilton Hotels for information on outages.
One employee at the Hilton Phoenix Tapatio Cliffs Resort in Phoenix, Arizona, told CNN that guests had to wait for a bellhop to open their rooms for them because an outage hit the software the hotel uses to make key cards.
Hertz, Dollar and Thrifty locations are open, according to a statement from Hertz.
“We are seeing an increase in volume at our call centers and sustained demand for bookings, reservation modifications and one-way rentals. Some customers might experience longer than anticipated waits, and we are working diligently to get people on the road as quickly as possible,” the statement said.
Are trains and other public transport systems affected?
Some train systems are reporting issues related to the tech outage. In the UK, National Rail reported “widespread IT issues across the entire network” on Friday. National Rail said UK train operators are unable to access driver diagrams at certain locations, so there’s the potential for short-notice train cancellations.
In Italy, the transport ministry said Trenitalia and Italo train networks were suspended after systems went offline. Passengers called emergency services and demanded to be let off the trains because of extreme heat, after enduring delays up to 140 minutes. Some trains on rural Italian rail lines have been stopped because of extreme heat.
In the United States, trains and buses in Washington, D.C., have been impacted by Friday’s outages, according to the US capital’s transit authority.
In New York, Metropolitan Transportation Authority (MTA) customer information systems went temporarily offline Friday morning, according to officials. However the MTA said “train and bus service is unaffected.”
Again, this isn’t an exhaustive list. If you’re set to travel soon, wherever you are in the world, it’s worth double checking your individual journey status before you travel.
