Thank you TWA884! I have flown VivaAerobus in the past and had a good experience.

Primary concern now is not money but reliability. If I could have gotten a backup out of SAN (absolutely cannot miss dates) I would book those VivaAerobus tickets in a heartbeat. I hear AeroMexico is even better. I'm just.. spooked. No notification?

Before I posted I googled all permutations of "volaris date change" that I could think of, and came up empty. I'm still surprised that dramatic date and schedule changes are treated with such blasé. I am not a veteran Mexico traveler, but I explore when I can.

Thank you for your help and all the best flying in 2024!
