Questions people ask first.
Why do the surcharges differ so much between airlines?
The operating airline sets the surcharge, but each program decides how much of it to pass on — which is why the same seat can cost wildly different cash through two programs. British Airways adds $486.20 to an American AAdvantage booking and $12.10 to the same seat through Atmos Rewards: same aircraft, same cabin, same day. The same cabin on the same day carries $5.60 in cash on American Airlines and $486.20 on British Airways.
Do I need an account with American AAdvantage to search?
No. Searching MilesZone is free and needs no account of any kind. You sign in to the program only at the moment you book, on its own site.
Does MilesZone book the seat for me?
No. We find the seat, show the miles and the cash side by side, and hand you the link. The booking happens with American AAdvantage directly.
