Am I entitled to compensation for a flight cancelled due to weather?
You are entitled to a full cash refund for any cancelled flight, including weather cancellations. Under 14 CFR Part 260, the airline must refund your ticket to the original payment method within 7 business days (credit card) or 20 calendar days (other methods). What you are NOT entitled to for weather cancellations: meals, hotel, or ground transportation. Those are only required for controllable cancellations like mechanical issues or crew problems.
Does the airline have to rebook me if weather cancels my flight?
Airlines will typically rebook you on the next available flight at no extra cost, even for weather cancellations. However, they are not legally required to rebook you on a competing airline for weather events. If you don't want to wait for rebooking, you can request a full cash refund instead and book your own alternative travel.
Can I get a refund for a weather-cancelled flight?
Yes. The DOT automatic refund rule (14 CFR Part 260) requires airlines to refund cancelled flights regardless of the cause. Weather, mechanical, crew shortage, operational — the reason doesn't matter. If the airline cancels your flight, you get a full cash refund. This applies even to non-refundable tickets. You do not have to accept vouchers or travel credits.
What's the difference between controllable and uncontrollable cancellations?
Controllable cancellations are the airline's fault: mechanical issues, crew scheduling, IT outages, operational decisions. For these, airlines must provide meals after 3 hours, hotel for overnight delays, and ground transportation. Uncontrollable cancellations include weather, air traffic control, and security events. For these, airlines must still provide a full refund, but are NOT required to provide meals, hotel, or transportation. The refund right is the same either way — the difference is only in the extras.
