Best fare drop trackers after you book (2026)
A fare drop tracker watches a flight you already bought. Some only alert you; others file the claim with the airline and the difference comes back, usually as airline credit. Below are the services that claim it for you, with cost and airlines, checked October 23, 2026. Disclosure: we make Fareward.
Why it matters: fares can drop up to 26% after booking, depending on how far out you book (CheapAir 2024 airfare study).

Real example (SFO→SJD · Aug 2026): a $632.62 airline credit after a one-day dip.
Some tools have paused Alaska and Hawaiian claims after an October 2026 airline policy change (NerdWallet, Oct 14, 2026). Check each service before you rely on it.
My flight price dropped after I booked. Can I get money back?
Usually yes, as airline credit, if you booked directly with the airline and are not in basic economy. Changing to the same flight at the lower price leaves a credit for the difference. Inside 24 hours of booking you can usually cancel for a full refund. Fareward watches your fare and files the claim for you on American, Alaska, Hawaiian, Delta, United, and Southwest.
What does Fareward cost?
Watching is free. The fee is 20% of the savings, only after a credit lands. If no credit lands, you pay nothing. No subscription.
Which airlines does Fareward cover?
American, Alaska, Hawaiian, Delta, United, and Southwest.
Do you need my airline password?
No. Fareward never takes your airline login or a 2FA code and never logs in as you. It files as your authorized agent.
Do I get cash or credit?
Usually airline credit, such as a United Future Flight Credit or Delta eCredit, not a card refund. Refundable fares and the 24-hour window are the exceptions.
How much can fares drop after booking?
Fares can drop up to 26% after booking, depending on when you book (CheapAir 2024 airfare study). Not every drop turns into a credit.
Which fare drop tracker files the claim for me?
Fareward, Autopilot, JetBack, Junova, pAiback, Refare, and Gondola AutoSave all claim the fare difference with the airline. Google Flights Price Guarantee pays a Google Pay payout instead, and only on badged flights.
