Yeah that would be courteous of them to do so but at the same time when you book with expedia you choose your outgoing flight where it states your layover time between flights. How slow customs or security is going or how big the layout of the airport is, ultimately isnt expedias fault. They dont care in the end how new you are at air travel or if you dont know how big or busy the airport your going to is. I found with short layover times where i gotta go through customs and security, i usually call ahead and ask what the standard time through customs and all that nonsense is so i can see if ill make my flight or not. God forbid theres any other delays with the first flight getting there. It's a nightmare. Lol
