(There's nothing fishy going on here. AA calls the front cabin of domestic flights F, but calls the same front cabin J/C on international flights with the same equipment. Just check out availability on any AA flight from mainland U.S. to the Caribbean, all of which is considered international by AA, regardless of the actual country. The front cabins are J/C. Perhaps they consider this a J/C ticket because it's part of an international itinerary. Regardless, it's a two cabin plane and you'll be upfront whether you're in J/C or F.) All other nonstop AA service NYC-DFW is on 738s out of LGA, nine flights per day. Nearby, AA has six nonstops per day EWR-DFW on the Mad Dogs.

Re chauffeur service and lounge access, if you haven't been notified that you're not getting it, what is there for you to do? Especially since reports so far seem to indicate that EY is providing these "ancillary services" as they're supposed to.
