FWAAA,
On a somewhat related topic, where do you think AA will use its winglet equipped 757s? seems like they are being set up for transatlantic work. Also, I can't help but think that if AA was serious about expanding its Pacific network it would move some of its 767s off transcon routes and even move some of the A300s back to transatlantic flights.
To add to Former ModerAAtor's excellent post (with which I agree), my guess is that the wingleted 757s will fly routes like the already announced JFK-NCL (starts in May) and the existing BOS-MAN and BOS-SNN. Rumors have circulated here that Northern Brazil is within range of MIA with wingleted 757s, so perhaps we'll see a couple new destinations there.
Additionally, LAX-SJU, which has been a 763, becomes a wingleted 757 next summer (yuck). I'd also look for them on DFW/ORD-ANC, currently 757s. Winglets will permit more payload on those long domestic segments.
I'll go out on a limb and predict JFK/BOS-BHX next year as well. IIRC, AA served BHX from ORD with a 767 a few years ago.
If AA hadn't just today announced the cessation of DFW-LIM, that would be a great candidate for the winglets. Currently a 757, but the winglets would allow greater payload. I'm sure there are a few more potential European and Central American destinations up AA's sleeve.
As to transcons, I assume the 762s will keep flying JFK-LAX/SFO until AA takes the plunge and copies UAL's ps with some 757s or really takes a plunge and orders some 787s, freeing up more 763s for transcons. Had fuel not gone thru the roof, AA might have joined LAN and ordered some more 763s, but today's fuel prices (nearly three times higher than four years ago) probably forecloses any possibility of any more 763 orders at AA.
Pacific expansion? I see tons of it already at AA. AA recently resumed DFW-KIX, just began ORD-DEL, tried and canceled ORD-NGO and begins ORD-PVG in April. Two new 777s arrive in time to help cover the China flights. AA will undoubtedly try to win some additonal frequencies in the next round of awards. As much as DL could use the revenue from China flights, I'm betting that CO and AA are the winners of future China frequencies.
Despite Boeing's good fortune over the past year or so, I'll bet AA could get several new 777s if necessary without waiting an inordinate amount of time. And morbid as it sounds, there's still the distinct possibility that eight low-mileage, low-hour, driven only on Sunday, RR-powered 777s might be on the market sometime in the near future.
Of course, who knows what happens with NW? Plenty of rumors that it and DL join forces and lots of speculation (mostly from me and NH/BBs) that AA will make some kind of play for NW to get a turn-key position of duopoly dominance in China and Japan, the better to go head-to-head with UAL.
Although AA flies a lot of 777 frequencies to LHR (all 777 at the moment), AA also flies 777s to South America (GRU/GIG and EZE) plus 2 daily DFW-NRT and one daily NRT flight from ORD, JFK, LAX and SJC. Plus DFW-KIX and ORD-DEL. AA seems to have spread its 45 777s around its network.
