one thing to note about these Euro style business seats is that I do not think AM is actively modifying their fleet to offer this product. I think they bought some 737MAX white tails that were destined to LCCs. Since travel demand to Mexico has been high due to lack of covid restrictions, AM needed the planes ASAP, so they did not bother upgrading the interior. I just hope this Euro Business product doesn't give AM upper management any ideas and make it a long term thing.

to the OP, are all MEX-CUN flights offering this? I would think some flights might have a proper business cabin.
