I left aruba yesterday to come home after 19 great days. American flight to Miami was delayed by 45 minutes. Originally scheduled at 3:20, left around 4. Got to the airport at 1:45 and it was a zoo. After checking in at American counter, walked outside and that’s where the end of the line was. Took us over 2 hours to get from checkin to our gate. I think many people changed their flights to come home early to avoid having to test to return back to US. That’s the only explanation I can think of, as it shouldn’t have been that busy on a Monday.
