As a Delta employee I am a frequent visitor Of Mexico on Am planes as well as Delta Planes.

Am is a wonderful airline everyone is very nice and very courteous. As far as who would u fly well....if it is a codeshare u might be able to get a better price with Am but if it is an Am plane it will be only Am flt attendants etc etc if it is a Delta plane only Delta flt attendants.

Like I stated Am is a very exceptional airline with wonderful employees. I have workd closely with the station managers here in Atl and they are great people. They will take good care of u. And also when it is an Am plane sometimes if there are Business seats available they will let u buy an upgrade for 40 dollars at the gate.!!!!
