I'm not here to get into a debate about how an airline identifies its operation. I'll note that MISWESTERNFLYER referred to the "NYC operation". NYC obviously encompasses LGA and JFK and could arguably include EWR. AA similarly refers its market in its hub/airport fact sheets as the "New York City Airports." Call them hubs, call them focus cities, call them nests, call them temples. IDGAF. I'll leave it to the marketers at AA to decide what they want to call it..
