BA newbie here...

Trying to book a flight for my parents to Cancun in May on AA.

First problem: over the past two days I've only been able to login to BA once. Every other time it says there is a problem with the website, and I can't get to the Members area.

Second problem: the one time I could get in to quote ATL-MIA-CUN and back, it gave me 36k Avios (correct) + ~$150 in fees. Wanted to see if this was accurate as I thought Avios had zero to little fees. I believe the fees were international things with Mexico, but again I can't login right now to confirm so... :|

Appreciate any pointers.
