I visited this Aeromexico lounge first during my layover since I was flying Aeromexico. When I arrived at 6am on a Friday, the lounge was quite crowded with most seats taken, although it cleared out a bit within 15 minutes.
The lounge is essentially a larger room with a smaller offshoot. It’s honestly tiny given that MEX is a hub for Aeromexico. Similar to US domestic lounges, it honestly doesn’t offer much to passengers.
The food options for breakfast were not great. A couple of pastries, fruit, yogurt, and cereals is all you’ll get. I did like that they had papaya, though, as at least it’s better than the sad melon melange you usually find in US lounges.
The other thing I liked about the lounge (there honestly wasn’t much) was that they had a whole bunch of coconut water. Perfect after a dehydrating flight. Aeromexico also offers coconut water in flight (and there were ads played on my flight for the brand that they carry).
All in all, not a lounge worth visiting.
