I know already hundrets and hundrets have already asked a similar question. I am flying in with AA from Heathrow (start in Germany serviced by BA) with a short stop in Raleigh/ Durham. As far as I know the procedure, I have to go thru immigrations, pick up my luggage, walk thru customs, drop my luggage again, pass security in order to get to my connecting flight to Mexico.
the whole iternary is with AA code numbers but the transfere time in Dallas is quite tight (I personally would say it is not even enough!) only about 1 hour.
Did I understood the process right? Is the transfere time to tight, and if, why is this sold in this combination?
