I did a brief search on the message boards and did not find anything - the Delta website does say extra baggage allowance but did not define the class.

Simple question: I am a DL PM with an Amex Delta Platinum card, my girlfriend is GM with an Amex Delta Platinum card, what kind of baggage allowance are we permitted with Aeromexico Basic fare. Looking to fly MEX-CUN in basic and we wanted each to check a bag, backpack as a carry on (so under the seat is fine)
