AA Checkin at Airport 24hrs before Flight for Doc Checks and BPs (no checked bags)?
Flying AA on 1 ticket CID-DFW-LHR-INV with very early morning CID departure. AA allows online check-in up to 24 hrs before flight. Does this permit in-person check-in at CID ticket counter 24 hrs in advance to complete all needed document checks (passport, PLF, negative COVID test results, etc) and get all 4 boarding passes? I live near CID and want to get all boarding passes 24 hrs prior to flight. Also, is it up to 24 hours before FIRST flight or FINAL flight of itinerary? Many thanks.
