We're two UK citizens flying from Glasgow to Chicago to Miami, and then back via the same route two weeks later, on American Airlines.
We're trying to find out a couple of things. First of all, will we need to clear US customs and Immigration at O'Hare? We have just over two hours between the two flights and my experience on domestic flights in the US has been you only need to check in around an hour before take-off.
Secondly, will we need to check in again at O'Hare or will we check all the way through to Miami when we check in at Glasgow?
Third, what about our bags? I seem to remember the last time I did this flight that my bags were checked straight through to Miami at Glasgow and I just had to go straight to the gate.
I've done this flight before but that was in August 2001, and I'm aware security/immigration procedures may have tightened up since then.
