I've booked an American Airlines round trip flight from London to Phoenix. For the return journey, the transit time at Dallas Fort Worth airport is 41 minutes.
I do not hold a residence permit of the US. So, I have to pass through immigration at port of exit which in my case is DFW.
I'm worried that 40 minutes transit time is not sufficient to go from Terminal C to D with immigration check. Since the complete travel is on a single PNR and is operated by AA they guarantee this somehow.
- Can I go through immigration directly at Phoenix?
- Would it be possible if I ask American Airlines that I prefer to take an earlier flight from Phoenix?
