What it uses

The same data as this site: the fare class charts, FareCompare and the mileage calculators, the Lounge Finder and the Great Circle Distance Calculator. Every answer links back to the page it came from. It does not track flights, does not need your account, and does not see your conversations beyond the question it is asked.
