What you can do with Flight Availability
Flight Availability is built for travelers who need to know what is actually open before they make a decision.
Find upgrade and award space before you commit
Before you redeem miles or submit an upgrade request, check which classes are available on your route. Filter by fare class to focus on the inventory that matches your redemption strategy.
Compare options the moment your plans change
When your original flight changes or gets canceled, check alternate routes, dates, airlines, and connections immediately. See which alternatives still have open inventory in your preferred class before you call the airline.
Filter to the flights that actually matter
Narrow results by airline, alliance, connection type, fare class, or point of sale. You see only the departures relevant to your search, not every option on the route.
Check Flight Availability
Search by departing airport, arriving airport, depart date, depart time, airline, and the class codes you want to show.

You want to know how full a flight is before choosing it
