Are you departing and what status do you have? If A terminal is busy and you are TSA pre check I’d go to C and walk internally! If A is busy check on line for wait times which are pretty up to date. I panic so I give myself two hours though I don’t always need it. Day of week matter too. Philadelphia airport has NO priority lane for first class anymore O it’s tsa or waiting
Daniel all international flights you must check in at least 3 hours before departure
I am sorry to say yesterday was the first time in the airport in 20 years so I really know absolutely nothing
