AA is the most heavily hub and spoke airline in the world. They do virtually no point to point.
AA's corporate policy is that you can't make money with a 4 engine airplane, originally used to justify MD/11 DC-10s when they retired their 747s, now extended to 777 over the MD-11 etc.
What AA is, however, is the businessman's airline, and as such have no interst in operating cattle cars as all the cheap tickets detract from the traveling experience for the businessman who actually pays the lions share of the revenue. They would rather leave the priceline.com pax behind and take more freight which is always ontime and rarely causes a return to the gate which is exactly why they pulled all those seats out of the aircraft to create "More room through coach"
AA hubs out of Dallas Chicago Laguardia Miami Sanjuan San Jose St Louis Raliegh Durham etc....
