Hi DavidH,
I have spoken with our team that looks after all the flights and they have informed me that where possible they always leave the most amount of connecting time as possible, especially outbound USA because of the immigration process. Unfortunately it's not always possible to have as much time as possible, but we will always ensure that the connecting times meet minimum connecting times stipulated by the airlines and airports. In this particular case, we have a 1hr 50 min connecting time, where the minimum connection time is 1hr 25 minutes.
My colleague suggested that I also share the following with you to make your connection as easy as possible (as taken from Atlanta's Airport website):
International inbound connecting at Hartsfield-Jackson for U.S. domestic travel: These passengers are arriving in Atlanta from a city outside the United States to connect on a domestic flight for travel within the United States.
• Passengers arriving at gates on Concourse F will process through immigration and customs at the Concourse F Federal Inspection Station (FIS). Passengers arriving at gates on Concourse E will process through immigration and customs at the Concourse E FIS.
• After the immigration inspection, passengers pick up their checked baggage.
• After the customs inspection, passengers’ checked baggage is rechecked and transferred to domestic connecting flights.
• Passengers are required to pass through a security checkpoint.
• To reach a connecting flight, passengers will follow signs to the Airport’s people mover system, The Plane Train, which connects the international concourses (E and F) to all other concourses and the domestic terminal.
I hope this information is helpful, but if you have any further queries please let us know.
Kindest regards
Julia
