Greetings!
Long time listener, first time caller….I have lurked in the shadows here for several years but as a former BA staffer, have somehow resisted the urge to post until now.
I am hoping one of the esteemed members here with a better knowledge of FRA than I do may have an idea of whether this is doable.

I am flying Condor on LAX-FRA in a few weeks courtesy of a good Alaska Airlines sale…but planning on connecting to BA on FRA-LHR with a 1hr30 connection.
I know I will be arriving at Terminal 1 and connecting to Terminal 2, non-Schengen to non-Schengen with no bags - and I should have my boarding pass for BA with me.

Anyone here familiar with such a connection and whether or not this is doable? I have only ever arrived at FRA and ended my journey there.
Thanks for any advice.
