It seems like there isn’t maybe an occasional 777 or 767 but I do not think AYT has any long haul flights, I could see Delta from JFK or United from EWR trying it out but who knows?
Never going to happen. DL/UA can not even make IST work. I know because I used to be a DL man for many years flying out JFK, DL72/73 to IST. It has been 5 years since I've switched to TK. Better scheduling, better hard and soft product, better mileage plan, better connections via IST and probably similar pricing if not cheaper.
DL/UA will not fly to AYT, same reason TK is not flying to Palma de Mallorca or the Canary Islands.
These are all low fare charter, tourists routes with little J or Cargo or transfer pax possibilities.
Before AYT, I would like to see some airline flying to SAW ( Istanbul's second airport) from New York.
