Hi. Is 90 minutes enough time to go through customs in Charlotte? We both are Known Travellers.
Are you flying back from Europe connecting in Charlotte to another domestic flight?
Yes that’s correct
Is it a single ticket?
If not, are checked bags involved?
No checked bags and all on American. Now that you’re asking these questions, I think it should be ok.
You should be OK. Charlotte is not that big and I doubt if more than one plane would be going through immigration at that time. And it is immigration and not customs. Customs is hand over your declaration sheet and move on. And if you have Global Entry it is almost nothing.
Oops misspoke!
