Is there any Web application that shows you a list of mileage programs that you can gain mileage on, given that you get on an flight X?
For example, if you get on a economy class with type S class from NRT to PEK in China Eastern Airlines, you can gain mileage on these programs (numbers and types are just illustration purposes only):
- Delta: 2310
- Alitalia: 1298
- Vietnam: 1298
- Korean Air: 2180
- Air France: 980
And it would be better if the service shows you not only the same alliance but a set of affiliated airlines.
Is there any such web service that enables you to compare and decide which mileage program to put your next flight mileage on?
