Question on Terminal change at Boston airport
 

I'm trying to use FF to go from LAX or SNA to CDG and back. Right now I've got outbound on hold. Return is available CDG-BOS-LAX but it says terminal change. There is a 2 1/2 hour layover but I was wondering how difficult will it be to change terminals at BOS?
Thanks

I will help if you tell us what operating airline you're considering for each leg.

It's not a problem. There is a free bus between terminals.

I'm sorry - I will be flying American airlines on both flights.

You should have enough time. You drop the bags off back to AA once you go through customs at Terminal E, then go take the shuttle, #11, back to Terminal B.

It ought to be fine. We've done AA international - domestic transfers at BOS with shorter times, and it was quite a hassle, but 2.5 hrs should be sufficient, providing your flight from Paris isn't too late.

However, when are you flying? I can see 1.5 hour and 3.5 hour layovers, but nothing with a 2.5 hour layover.

And shuttle bus runs very frequently - should not be a problem.
