We were flying AA with a 4 pm departure. Arrived at airport and the first line. While waiting seemed about everyone had one of their bags checked. Open it up on the floor and scan with a small black wand which I would think was for explosives. Closed up and checked COVID test results by another agent then to a table to fill out a form which the agent there kept. One table - 2 pens. Quick and easy. Checked in at counter and then directed to another table to fill out another form - 2 tables, 4 pens, before going through security. Basically name, passport number, citizenship and date of arrival etc. This gets handed over to agent while showing boarding pass etc. My wife's purse had to be check twice and scanned twice. Turned out it was her hair ban. If you know the Cozumel waiting area you now have half the seating as before. Very crowded with 2 planes of passengers waiting. We just went into the lodge which was $35 US per couple. Quiet and private bathroom. Entrance fee gets you some snacks and 3 drinks a piece. Drinks are very limited. They look at you boarding pass and let you know when your plane is boarding. No announcements in lodge.
Hope this helps.
