Another basic question! I don't know the right place to ask it, but it does relate to the OTP-PHX run, which I'm doing over the Easter weekend, so I'll try here first!
I've never flown on AA before, but I've three domestic flights with them over the trip (the rest are BA operated) so, my question is: how strict are they on cabin baggage size? My trusty carry-on has never been measured in all my travels around Europe and parts east, but is a bit bigger than AA's stated limits (mainly in the width). For those with domestic US AA experience, is this going to be an issue?
