Moderator's Note - Topic Drift
Folks,
This thread is about clearing customs in Atlanta when having a connecting flight onward (the thread title has been edited for clarification). There is nothing to indicate that the OP is planning to abandon their domestic segment and end their flight in Atlanta. The OP is very specific that they are connecting to a domestic flight - "Flying into ATL and then changing to US flight."
This is a fact-based informational forum where members come to ask questions and get information to travel with minimal hassle.
Unless the OP returns and adds there is a possibility that they will terminate their trip in ATL, future posts speculating what happens when one wants to end their trip before the final ticketed destination will be deleted without further notice.
