Does anyone know how far in advance I can check-in and check baggage at PHX on AA? I know for some airports it is only 4 hours but PHX is not on that list. I would like to check in and drop one or two bags the evening before 6-8 PM for a 10 AM flight the next day (because I need to return my rental car the night before and getting the two bags to the airport on the hotel shuttle and into the terminal is going to be hard by myself).
This comes up every few months, and for the day before I think the answer is always no, unless it’s for a flight departing just after midnight— I’m not sure what the official cut off is though.
