Just flew PVR-SEA Wednesday. Had ticket PVR-SEA for Monday on Alaska but decided to depart Wednesday on Delta award 2500 points + $70. Took covid antigen test at airport 450 pesos.- Took 45 minutes 30 of which was waiting for test results. No line at check-in. Bottle neck was just before security where they ask you to scan and fill out an on-line covid survey before proceeding through security. That said the Alaska did have a line at check-in.
