Nearly 5,000 flights were canceled across the US after an FAA ground stop. Here's what to do if your trip was affected.

• Nearly 5,000 flights were canceled after a nationwide air traffic control outage on Friday.
• This is considered an uncontrollable disruption, so airlines aren't required to provide freebies.
• Here's what you can do if your flight is delayed or canceled.

US airlines are canceling thousands of flights after a rare air traffic control outage affecting the US.

As of 7:45 p.m. Eastern time on Friday, FlightAware data showed that nearly 5,000 flights to, within, and from the US had been canceled since the Federal Aviation Administration issued a nationwide ground stop — meaning no flights could depart — around 3:45 p.m.

The stop was lifted around 8:30 p.m., but after so many cancelations, flight chaos is nearly guaranteed.

If you're wondering what your options are as the terminals pile up with people frantically trying to get a hotel or food voucher — don't rely on your airline to help out.

According to the Department of Transportation, certain delays and cancellations caused by, for example, an ATC outage, are considered "uncontrollable" disruptions.

That means airlines are not required to provide freebies such as hotel stays or food vouchers. Don't confuse the rules with the DoT customer service dashboard, which shows passenger compensation for flights disrupted by controllable factors, such as maintenance or crew scheduling. Pilots or flight attendants timing out due to the outage would not fall under crew scheduling.

Airlines may offer goodwill vouchers to help out affected customers, but don't bank on it. Customers who book their own hotel or other transportation, such as a rental car or train, may be able to get eligible expenses reimbursed by their credit card.

Here's what to do if your flight is disrupted.

1. Know your rights as an airline passenger in the US

According to the Department of Transportation, there is no law requiring US airlines to compensate passengers for disruptions caused by uncontrollable events, such as weather. That also includes air traffic control delays.

The only rule carriers must follow is to refund customers for cancellations, even in cases of uncontrollable events. And that does not mean travel credits or vouchers — it must be cash, and includes any add-ons, such as bags or seats.

If you choose to travel but your flight is delayed or canceled, ask the airline for the reason — ideally in writing — so you know what you're entitled to. Airlines have different policies for disruptions they control, like crew or maintenance issues.

The DoT's Airline Customer Service Dashboard — launched in 2022 — shows what the 10 largest US airlines promise in those cases, including rebookings, meal vouchers, and hotel accommodations.

2. Monitor your airline's app for rebooking options

When a flight delay or cancellation is announced, expect people to flock to the nearest customer service line for assistance, and for the phone lines to clog.

Wait times can be painfully long, and the best alternatives will likely go quickly. However, some airlines offer the option to rebook on their website or mobile app and waive any fees, making it sometimes easier to make changes online than in person.

If all available options are exhausted, have a plan B, such as waiting to speak with a live agent, contacting the airline through social media, or booking a hotel for the night.

Direct messaging on Facebook or Twitter can actually serve as a virtual placeholder, and you may hear back via chat before speaking to a live agent.

Here are the phone numbers for each airline:

• Alaska: 1-800-252-7522 or text 82008
• Allegiant: 1-702-505-8888
• American: 1-800-433-7300
• Avelo: 1-346-616-9500
• Breeze: No phone number to call, but you can text the airline at 501-273-3931. If you call this number, it'll tell you different ways to contact Breeze, like via email or Facebook Messenger.
• Delta: 1-800-221-1212
• Frontier: No phone number. The best way to contact Frontier is via online chat or email.
• JetBlue: 1-800-538-2583
• Southwest: 1-800-435-9792
• Spirit: 1-855-728-3555
• Sun Country: 1-651-905-2737
• United: 1-800-864-8331

3. Ask for a hotel or meal voucher

For controllable delays or cancellations that result in a customer waiting at least three hours for a new flight or requiring an overnight stay, several airlines will offer meal or hotel vouchers. 

Carriers offering both are Alaska Airlines, Allegiant Air, American Airlines, Delta Air Lines, Hawaiian Airlines, JetBlue Airways, Southwest Airlines, Spirit Airlines, and United Airlines, per the DoT dashboard.

Frontier Airlines is the only carrier that does not offer accommodations in the event of an overnight delay or cancellation, but it will provide a meal voucher.

For US airlines not listed on the dashboard, or in cases where the disruption is uncontrollable (like because of a winter storm), or if the compensation is unclear, simply ask.

It never hurts to request a meal or hotel during flight disruptions, and you might get lucky with a goodwill gesture from the carrier.

4. Check if your credit card company offers travel insurance

Several major banks offer credit cards with travel insurance, such as Chase's Sapphire Reserve and American Express' Platinum Card. Both offer trip protection, meaning customers who purchased their flights with those cards can reap the benefits.

For example, during a major storm system, it's likely many passengers will end up stranded in random cities across the US.

However, banks with travel insurance included can reimburse cardholders for unexpected expenses outside their control, including hotel, meal, and transportation costs. 

Travel insurance does not apply in all circumstances, like short delays, so be sure to check your policy before making a claim — but it also doesn't hurt to make the claim anyway, even if the answer is no.

5. Know when to walk away

Delays and cancellations are inevitable. Don't spend all day sitting around waiting — give yourself a cut-off time. Once that moment passes, consider alternative means of getting to your destination, such as driving or taking a bus or train (which may also be covered by travel insurance).

If you are stuck in another city and have no other option but to stay in a hotel or wait at the airport, decide how you want to spend your time and make a plan.
