SkyTeam Elite Plus status was not recognized by Aeromexico (it was on my outbound flight - I even got upgraded - the return flight was a complete 180 degree experience). The flight was not properly catered. No wine available other than in first class, only beer option was Michelob Ultra. Not the crews fault, likely just poor logistics with catering and ground personnel. At the time, masking was required but not properly enforced at all.
