I'm a non-US citizen flying to the US with a changing time between flights of 1:50 in Atlanta. Since this is rather on the short line according to this answer, I was wondering what to do in case of a delay. Since this will be my port of entry, I have to pick up my bag go trough border control, put the bag on field again, and change from international to domestic terminals, etc.
I know that if you are late in Europe, you can ask somebody; in most cases they let you cut the waiting line in customs/check in/etc. if you would otherwise miss the flight.
Is it also acceptable to approach staff with such a request at an US airport?
