What an award flight alert does
An award alert watches award availability for you and emails you the moment space opens — so you can book with miles before the seats are gone, without checking every day.
- AwardTool re-checks your route across the booking programs it supports and notifies you when award seats appear.
- Set the cabin, travel dates, passengers and a points ceiling; tighten or widen them whenever you like.
- You decide which booking programs to watch — alerts follow award space by route and program, not a single airline's schedule.
Award space can vanish quickly, so an alert is usually faster than manual searching.
