recent experience flying in with pets?

We are finally arriving to move into our new home at the end of July, and we are bringing our dog, Ray Ray, who will be in baggage. We've done all the research for the airline and their requirements, and I've found the info that health certificate and parasite treatment is no longer required since 2019 -- both on other websites and helpful threads here. (We'll still have a health certificate since the airline requires it.)

Just trying to cover all our bases... anyone brought an animal into Zihua airport recently and can share your experience, good or bad? Any tips or measures we can take to ensure as smooth a process as possible? Any details you wish you knew ahead of time?

One specific point... the airline says they could decline to take him if the destination temperature is too high. Has anyone run into that before and had it actually enforced?

Thanks in advance!
