    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.
