Most no-change-fee airlines (United, Delta, American, and others) will give you the difference back as a travel credit if the fare on a flight you already booked drops before departure. The catch: you have to notice the drop and rebook the same flight while it's cheap. Flight Price Protection watches the fare for you and tells you the moment it's worth rebooking.
Go to Watches in the sidebar and use Protect a flight you booked. Paste the airline confirmation email or a GDS/Sabre PNR — JourneyFuse reads the route, airline, flight number, date, cabin, and passenger count, and asks you to confirm the fare you paid. That paid fare becomes the line we measure every future price against.
A booked-flight watch only pays off if we compare apples to apples. A cheaper fare on a different airline can't be rebooked for a credit on the airline you booked, so showing it as a "drop" would be misleading. When you set up the watch, you choose how literally to track it:
| Setting | What counts as a drop | When to use it |
|---|---|---|
| The same flight (default) | Only the exact airline + flight number you booked, on the booked date | Standard protection — the only fare you can actually rebook for a travel credit. Requires a flight number from the confirmation. |
| Same airline, same day | Any flight on the same airline and route that day | You'd happily move to a different time on the same airline if it's cheaper |
| Any airline, same day | The cheapest fare on the route, any carrier | You just want a general signal that the route got cheaper — note this can't be rebooked for a same-airline credit |
The default is the same flight whenever we can read a flight number, otherwise same airline. You can change it any time.
When the same flight drops below your booked fare, the watch flips to CLAIM and surfaces the amount waiting. Rebook the identical flight with the airline — most no-change-fee carriers issue the difference as a travel credit (valid about a year, same airline). Until your exact flight is confirmed cheaper, the page shows "We're tracking your exact flight — no lower fare confirmed yet," so a stray different-airline price never sends you chasing a credit you can't claim.
Each drop gives you two actions:
Monitor cruise and hotel prices after booking — get alerted when prices drop so you can rebook and save your clients money.
