Ground stops halt departures. Ground delay programs space them out. Here is how each one affects your flight time.
Ground stop
Departures headed to the affected airport are held completely. Nobody leaves until the FAA lifts the stop or lets flights go in batches.
Ground delay program
Flights still leave, but each one gets an assigned departure time so the arrival airport isn't overloaded. The FAA publishes the average and maximum delay. When San Francisco has wind, for example, the program might show an average delay over two hours with some flights pushed much further.
Which is worse?
A ground stop is more abrupt but often shorter. A ground delay program can run for most of a day. Both show up on our live FAA list, with the average and maximum delays where the FAA reports them.
Tip: the app is usually faster than the phone line or the counter. Try all three at once.
Your rights
Do I get a refund?
Under U.S. DOT rules, if your airline cancels your flight or changes it significantly (3+ hours domestic, 6+ international) and you turn down the alternative, you're owed a cash refund to your original payment method. You don't have to accept a voucher.
Will they pay for my hotel or meals?
No federal law requires it. Many airlines commit to meals or hotels for delays they control. Weather and FAA air traffic holds usually don't count. Check the DOT dashboard for your airline.
Should I rebook now?
If your flight is cancelled, rebook in the app while you wait in line or on hold. Seats go fast. If it's only delayed, wait for an update before giving up your seat.
Why is there a ground stop?
Common reasons are weather (wind, thunderstorms, low visibility), equipment outages, staffing shortages and runway problems. The FAA status feed lists the reason for each active stop or delay program.
How long do ground stops last?
Most last 30 minutes to a few hours. The FAA often posts an expected end time and can extend or lift it early.
Do I get compensation for a delayed flight?
In the U.S., airlines don't owe cash compensation for delays, though many offer meals or hotels for delays they cause. In Canada, the Air Passenger Protection Regulations can require compensation for delays within the airline's control. In the EU and UK, EC 261 can apply.
What if I miss my connection?
If both flights are on one ticket, the airline must rebook you at no cost. Ask for the next available flight, including partner airlines.
