I think part of this may be to intimidate BA(see AA second LGW-DFW 777, and LGW-RDU 777 flights) into coughing up slots, but I figure if they really wanted to do that, they would make all of their LHR flights 777s.
The economy has been improving a tad bit, but I do think AA is over doing it a little bit. They should have increased service to bigger cities with a market instead of second or third tier cities(no offence
) or cities without much competition.
As for aircraft, AA is getting rid of the 727s and 717s(As previously noted), but they do have planes in temporary storage, so they can go ahead and pull those back into the air.
Give me a break, I created this username when I was a kid...
