recent experience flying in with pets?

Jake and I have corresponded but here is a shortened version

Out of 5 times flying to Zihua from Alaska on Alaska Air, and 5 return flights, I had to go thru Guadalajara in 2020 and 2021 resulting 5 flights for my pooch, 2 on Aeromexico, no difficulties either time. The trips thru GDL were due to Alaska Air using Airbuses on the Zihua route.The vet inspection is more formalized at GDL, they have a regular office and full time staff.

My comments about Zihua vet inspection are based on 2017 thru 2019, 2 times each year.

Passing into Zihua from LAX or in Jake s case from SFO is not difficult with a pet. You are reunited with your pet in the baggage area so the delay is seldom more than 15 or 20 minutes. Sometimes it takes a while for the Mexican inspector to come to the baggage area to locate you with your dog and then look at your vet papers. Even though not required anymore, I normally ask my Alaskan vet to list in the health inspection that my dog has received tick and heartworm medication . Your dog will need to take these meds to live in Zihua.

You may want to call Alaska Air about the temperature restriction, I never encountered it in flying into Zihua.
