Aeroméxico Schedule Changes - Bad for YVR

For YVR-ZIH-YVR I have previously flown on Alaska Airlines. But they changed their schedules, now requiring an overnight stay both southbound and northbound.

Then I went to WestJet, but it won’t take my dog in cargo. So it was on to AeroMéxico. I could get a 23:55 departure. This wasn’t ideal, but I would have a few hours layover in MEX, and be at ZIH about 10:30. (Well, theoretically. Sometimes AM would sell me that, then change my MEX-ZIH to an afternoon arrival.)

A couple of days ago I got an email from AM. They have changed my 23:15 departure on October 12 to 15:40, making my MEX layover 11 hours long, from 22:20 to 09:30. With my dog.

I checked other dates and didn’t see any 23:15 departures from September 1 until the middle of December. Getting to ZIH is becoming increasingly challenging.
