Airline Price Drop After Booking: What Each US Airline Gives You

Quick answer

If your flight price dropped after booking, you can usually get the difference back as airline credit on any of the major US airlines. That holds as long as you're not in a basic economy fare and you booked with the airline directly. Most big US airlines dropped change fees on standard economy and above, so changing to the same flight at the lower price leaves you with a credit for the difference. Two rules matter everywhere: basic economy rarely qualifies, and the savings are credit, not cash, unless your ticket was refundable or you're inside the 24-hour window.

The 24-hour rule (works almost everywhere)

If the price drops within 24 hours of booking, cancel and rebook. Major US airlines let you cancel within 24 hours for a full refund to your original payment when you book directly. For some, that applies only when the trip is at least 7 days out. This is the one window where basic economy is fine too.

Airline by airline

Airline What you get on a drop Basic/lowest fare Credit life (typical)
United Future Flight Credit for the difference Basic Economy: no changes after 24h ~12 months from original ticket
Delta eCredit for the difference Delta Basic: change fee + difference Typically 1 year from purchase
American Trip Credit for remaining value Basic Economy: no changes after 24h 12 months (AAdvantage, online), 6 months otherwise
Alaska Cancel to Wallet and rebook (Main/First) Saver: 50% credit if cancelled 14+ days out Check your Wallet
Southwest Flight credit, or refund on refundable fares Basic: must upgrade to change 12 months (Choice), 6 months (Basic)
Hawaiian Credit for the difference on eligible fares Check your fare rules Check your fare rules

United

United has no change fee on standard Economy and above. If you change to the same flight for less, the difference becomes a Future Flight Credit. Basic Economy can't be changed after 24 hours. If united.com won't show your exact flight, use the app chat or change to another flight and back. Full guide: United price drop after booking.

Delta

Delta says that when your new flight costs less, "you will receive an eCredit for the difference" (Delta FAQs). Classic and Extra fares have no change fee from the US, Canada and Caribbean. Basic pays a change fee. Full guide: Delta price drop after booking.

American Airlines

American turns leftover value from an exchange into a Trip Credit (aa.com travel credit). Do it online, because American lists a $50 fee for Reservations assistance on changes. Add your AAdvantage number first for the longer credit life. Full guide: American Airlines price drop after booking.

Alaska Airlines

As reported in October 2026, Alaska's updated Lowest Fare page says it can't apply price adjustments after purchase. On Main and First Class, though, there's no change fee (Alaska flexible travel policy), so you can cancel to your Wallet and rebook at the lower fare. Saver fares get only a 50% credit when cancelled 14+ days out (Saver). Full guide: Alaska Airlines price drop after booking.

Southwest

Southwest "doesn't charge fees to change your flights." When the new fare costs less, it refunds the difference on refundable fares, or holds it as a flight credit (Southwest fare information). Basic fares can only be changed by upgrading, and Basic credits expire in 6 months. Full guide: Southwest price drop after booking.

Hawaiian Airlines

Hawaiian now belongs to the same group as Alaska and shares the Atmos Rewards program, and its rules are being lined up with Alaska's. Hawaiian has generally had no change fee on Main Cabin and above, and leftover value becomes a travel credit. Its Contract of Carriage has referenced travel credit when the fare on the identical flight drops. We couldn't load Hawaiian's help pages on Oct 11, 2026, so check your fare rules and the Hawaiian Contract of Carriage before relying on this. Basic fares (Main Cabin Basic) are the usual exception.

Step by step: the DIY method for any airline

  1. Check the same flights, date and cabin on the airline's own site. Compare like with like (Main to Main, not Main to Basic).
  2. Log in with your loyalty number so the credit lands in your account. On American, this also gives you the longer credit life.
  3. Use Change flight in the airline's app or website and pick the same flight. Online is usually free. Some airlines charge for phone help.
  4. If the tool won't price it, try the airline's in-app chat, or (where allowed) cancel for credit and rebook right away.
  5. Screenshot the old fare, the new fare and the credit amount.
  6. Note the credit's expiry. On most airlines it doesn't reset when you change.

The catch

  • Basic economy. Little or no flexibility after 24 hours. Cancelling usually costs a fee that's larger than a typical drop.
  • Credit vs cash. Unless you bought a refundable fare, expect airline credit, not money back on your card.
  • Expiry. Credits often keep the original ticket's date. Check before you rely on them.
  • Third-party bookings. If you booked on an OTA, changes usually have to go through it.
  • Mixed tickets. Partner flights, cash-plus-miles, and companion fares often need an agent, and the rules vary. Check your fare rules.

How to watch your fare automatically

Every one of these methods depends on catching the drop. Fareward watches for you. Forward your airline confirmation to [email protected]. Fareward tracks the fare on your same flights and cabin. If it drops, it files with the airline as your agent. You don't share any airline password. The difference lands as airline credit, which you keep.

Fareward works with United, Delta, American, Alaska, Southwest and Hawaiian. Watching is free. Fareward charges 20% of the savings, only after a credit lands. If nothing drops or your fare rules don't allow a claim, you pay nothing. Since it's airline credit rather than cash, it's best for people who'll fly that airline again.

FAQ

What happens if you book a flight and the price drops? On most US airlines, if you're not in basic economy, you can change to the same flight at the lower price and keep the difference as credit. Within 24 hours of booking, you can usually cancel for a full refund instead.

Do airlines refund the difference in cash? Usually only for refundable fares or within the 24-hour window. Otherwise you get airline credit.

Does basic economy ever qualify? Rarely after 24 hours. Basic fares either can't be changed or carry a fee that often exceeds the drop.

Which airline is easiest for price drops? Southwest and Delta spell out their fare-difference rules most plainly. United and American work well on standard fares. Alaska now uses cancel-and-rebook on Main and First.

Is "airline price drop protection" a real thing? A few booking sites and card programs have offered it, and terms vary. With the airlines themselves, the "protection" is really the no-change-fee policy plus credit for the difference.

How long do airline credits last? Typically 6–12 months, depending on airline and fare. Many keep the original ticket's date. Check your account.

Can I automate this? Yes. Fareward watches your booked fare for free and files for credit when it drops, keeping 20% only after a credit lands.
