What are the new rules for cancelling flights?

Under U.S. Department of Transportation (DOT) rules, you are entitled to automatic cash or original-form-of-payment refunds when an airline cancels or significantly changes your flight and you choose not to accept alternative rebooking, vouchers, or credits.

Key Flight Cancellation & Refund Rules

• Automatic Refunds: Airlines must issue refunds automatically—without you having to jump through hoops—if you reject rebooking or travel credits.
• Refund Timelines:
  • 7 business days for credit card purchases.
  • 20 calendar days for cash, check, or other payment methods (including award miles).
• What Qualifies as a "Significant Change" (Eligible for Refund):
  • Domestic flight schedule changes or delays of more than 3 hours.
  • International flight schedule changes or delays of more than 6 hours.
  • Changes to the arrival or departure airport.
  • An increase in the number of connections.
  • Downgrades to a lower class of service (e.g., business class to coach).
  • Aircraft swaps that make the flight significantly less accessible for a passenger with a disability.
• 24-Hour Risk-Free Cancellation: If you book a ticket at least 7 days before departure, the airline must either let you cancel for a full refund within 24 hours of booking or place a free 24-hour hold on the ticket price.
• Ancillary Fee Refunds: Airlines must automatically refund fees for extra services you paid for (such as seat selection, Wi-Fi, or checked bags) if the airline fails to provide them or if your bag is significantly delayed (over 12 hours for domestic flights, or 15–30 hours for international flights).

You can check current airline commitments and track carrier performance on the DOT Airline Cancellation and Delay Dashboard.

JetBlue Airways had the highest overall rate of combined flight cancellations and delays among major U.S. carriers over a recent 12-month tracking period (June 2025 to May 2026), disrupting nearly 30% of its scheduled flights.

Worst U.S. Airlines for Disruptions

Based on Department of Transportation data analyzed over that year-long period, the top carriers with the highest combined rates of delays and cancellations include:

• JetBlue Airways: 29.29% disruption rate
• PSA Airlines: 29.26% disruption rate
• Spirit Airlines: 29.11% disruption rate
• Frontier Airlines: 28.88% disruption rate
• American Airlines: 27.42% disruption rate

Daily Operational Disruptions

For day-to-day operations and specific weather or airport events (such as recent disruptions at hubs like Dallas Fort-Worth or Chicago O'Hare), carriers like Southwest Airlines frequently log the highest raw volume of total delays and cancellations due to the sheer size of their flight network.

Airlines do not have a set or guaranteed amount of advance notice for cancelled flights, as cancellations can happen weeks in advance or just minutes before departure due to weather, mechanical issues, or crew shortages.

Notice Timelines and Rules

• Short-Notice and Day-Of: Many cancellations due to unexpected weather, air traffic control, or sudden mechanical issues occur with very little warning—sometimes right at the gate or while passengers are already boarding.
• Advance Schedule Changes: When airlines proactively trim their schedules or cancel flights ahead of time, they typically notify passengers via email or app notifications days or weeks in advance.
• Regional Regulations (EU): Under rules like EU Regulation 261/2004, airlines must inform passengers of cancellations without undue delay. If they give less than 14 days' notice, you may be owed cash compensation unless the cancellation was caused by extraordinary circumstances (like severe weather).
• United States Policies: There is no federal legal requirement for a specific minimum advance notice period in the U.S. However, if an airline cancels your flight for any reason and you choose not to travel, you are legally entitled to a prompt full cash refund rather than just a voucher. You can track carrier commitments on the US Department of Transportation Dashboard.

You can get a full refund for a flight if you cancel within 24 hours of booking (provided you booked at least 7 days before departure) or if the airline cancels or significantly changes your flight.

When You Are Guaranteed a Full Refund

• 24-Hour Rule: Under US Department of Transportation regulations, if you book a ticket at least 7 days before departure, you can cancel within 24 hours of booking for a full refund with no penalty.
• Airline Cancellations or Major Changes: If the airline cancels your flight, or significantly delays/changes it (typically 3+ hours for domestic or 6+ hours for international flights) and you choose not to travel, you are legally entitled to a full cash refund to your original payment method—even on non-refundable tickets.
• Refundable Tickets: If you purchased a fully refundable fare, you can cancel before departure and receive a full cash refund.

When You Won't Get a Full Refund

• Non-Refundable Tickets: If you cancel a standard non-refundable ticket outside the 24-hour window, most airlines will only give you a travel credit or voucher (minus any cancellation fees), not cash back. As noted by users on Reddit, passengers are generally not legally entitled to a cash refund for voluntary cancellations on non-refundable fares.

If your flight is canceled due to a government shutdown, you are legally entitled to a full cash refund from the airline if you choose not to travel, even on non-refundable or basic economy tickets.

Your Rights and Options

• Full Refunds: Under Department of Transportation rules, canceled flights or significant delays (3+ hours for domestic, 6+ hours for international) qualify you for a complete refund to your original form of payment.
• Free Rebooking: Airlines must rebook you on the next available flight with their airline or a partner carrier at no extra cost.
• No Cash Compensation: U.S. airlines are not federally required to pay cash compensation, meals, or hotel vouchers for delays or cancellations driven by national aviation system shortages. Any lodging or meal help is given at the airline's discretion.

What You Should Do

• Check Status First: Use your airline's app or check the FAA site before leaving for the airport.
• Rebook via App or Phone: Skip long airport lines if possible by using the airline app, calling customer service, or utilizing international support numbers for faster connection.
• Look at Alternatives: Consider trains, buses, or driving if widespread air traffic controller shortages severely disrupt schedules.
• Check Credit Cards: Review your credit card benefits, as some travel cards offer trip delay or cancellation insurance that covers meals and hotels.
