Frontier cancelled or delayed my flight — what do I do, and what am I owed?
Frontier is an ultra-low-cost carrier, and that shapes your disruption strategy in two ways. It doesn't interline, so it won't move you onto another airline, and it often flies a route only once a day — so 'the next Frontier flight' can mean tomorrow. What doesn't change: the DOT automatic cash refund rule applies to Frontier just like every other US airline.
Here's the playbook: how to move fast when Frontier cancels or badly delays your flight, when to take the refund and rebook yourself on another carrier, and exactly what Frontier owes you.

1. Check when the next Frontier flight actually is
Frontier often flies a route just once a day, so first find out whether its next seat is hours or a full day away. Check the app immediately. If the next Frontier flight gets you home in reasonable time, self-rebook onto it right away before the limited seats fill. If it doesn't, move straight to taking the refund and finding another carrier.
2. Claim your automatic DOT cash refund
The DOT rule applies to Frontier in full. If Frontier cancels, or significantly changes your flight (a domestic delay of 3+ hours), you can decline the new schedule and take a full cash refund to your original form of payment, even on the cheapest fare. Frontier must pay it within 7 business days for cards, 20 days otherwise. Don't accept a travel credit unless you want one.
3. Buy your own seat on another carrier if Frontier is full or a day out
Frontier won't endorse you to another airline, so if its next flight is too late, your fastest way home is a new ticket elsewhere. Take the DOT cash refund for the unused Frontier flight and book the alternate directly. Reroute prices the whole market so you can find the cheapest fast option rather than guessing.
4. Get a hotel and meals if stranded overnight
When the cancellation is within Frontier's control (mechanical, crew, IT) and you're stuck overnight, Frontier's Contract of Carriage and DOT commitments cover reasonable hotel and meal costs. Ask at the desk, screenshot any offer, and keep receipts — as an ultra-low-cost carrier, Frontier expects documentation.
5. Rebook and claim in parallel
Getting home and getting your money back are separate tracks. Lock in a seat first — Frontier's or another airline's — then file the refund and any expense claims. Because the refund funds your alternate ticket, request it the moment you know you're not flying Frontier.
Get home for $24 — even when Frontier can't
Frontier won't rebook you on another airline and may not fly your route again until tomorrow. Paste your cancelled or delayed Frontier itinerary and the time you need to land, and Reroute scans every carrier flying your route — not just Frontier — then hands you a ranked recovery plan in minutes. The free search shows your options instantly; the $24 plan gives you the full ranked itinerary to book right now.
