Aeromexico used their new 787 to and from Los Angeles for a while but this was a fleeting phenomenon (only before I booked unfortunately). Instead, the airline uses two separate 737s right now.
At LAX, Delta just changed to the same terminal as Aeromexico, so the Air Canada lounge will likely become a Delta Sky Club. Aeromexico’s Salon Premier lounge at MEX is a simple and crowded affair (it is also a Priority Pass lounge), where the Internet comes and goes and there are loud announcements and just a few snack options. The good news is that the barista makes excellent coffee on request.
Boarding agents for my flights were helpful but very laissez-faire and this also extended to flight attendants. There is minimal English so you can break out your few words of Spanish. Most staff are friendly but also decidedly disinterested; there is really no attention to passengers or to any detail.
The newer 737 version has 8 business class seats and a simple IFE, while the older version has no IFE and just 6 business class seats.
I experienced both the red-eye from Los Angeles (the newer model) to Mexico City and the daytime flight back to Los Angeles from Mexico.
The leather seat is like a domestic first class one that we are used to. It seemed a little wider and more plush than what I expected (but that might have just been me) but the seat pitch is rather short at 37 inches.
The older 737 version (at least) has no WiFi, although Gogo streaming is advertised at the gate.
The food Aeromexico serves isn’t great but it’s edible if you are really hungry (I wasn’t, luckily).
There is a pre-departure non-alcoholic drink on offer, though, as well as champagne.
Aeromexico isn’t too terrible a choice and delivers a similar product that most American airlines do. However, most American airlines have invested heavily in technology, lounges and WiFi. This is missing from the Aeromexico experience, with a broken iPhone app, a crowded lounge and no technology onboard. It’s not a deal-breaker but United, American and Delta do a better job than Aeromexico.
