I have a question that someone might be able to answer on this thread...
I'm planning on doing the OTP-PHX-OTP run with an LHR-OTP-LHR wrapped around it. I have a b2b with 50min turnaround at OTP, but this is LHR-OTP on a BA booking, and OTP-LHR on an AA Booking. Usually, with the turnaround thread info, it doesn't look like it'd be a problem, but I'm a bit concerned I need to be checked in on the AA journey before I get to OTP if I'm going to make it before the check in close.
I'm wondering, can I check in online for the OTP-PHX-OTP journey with AA, travel the first leg of the LHR-OTP-LHR leg and stay airside to start the OTP-PHX-OTP journey? I'll be hand luggage only.
