The thing is that AeroMéxico does not accept that my status does not appear on other airline's reservation system.
I made a quick test: tried, besides mine, two other platinum numbers belonging to colleagues. Result: none is recognized as Elite by CO (priority seating test)
Tried two gold members: result: recognized as Elite and offered priority seating...

Called Air France and I got the same result: If the system does not pop up the elite status, no priority seating Guess I'll have to get early for my flight.

If anyone has any other idea or can give me a hand, it will be greatly appreciated (a skyteam or AM insider, perhaps )

Cheers,
