AA has a very large fleet of B-757-200s. Most are less than 12 years old. AA is currently modifying the B-757-200s they own/lease (with RR engines) with winglets.
However, when AA bought TWA, the also received almost new TW B-757-200s (with P&W engines). These are some of the last B-757s built. IIRC, TW ordered these airplanes in 1998-2000. AA continued to take delivery of these airplanes from Boeing after they bought TWA. So, these B-757s have plenty of years of service left in them.
I know that because the TW B-757s really don't fit in the AA fleet as not only are the engines different, but so is the avionics suits. But, the question remains, will AA modify these airplanes with winglets along with the original AA airplanes?
Even if AA eventually sells these B-757s, or returns them to the lease holders, AA still plans on flying them for at least a few more years. The winglet modification will pay for itself within 6-12 months, depending on utilization. The winglets will also increase the value of these jets. The winglet mod gives around a 5-7% reduced fuel comsumption, and at least a 7% decrease in drag. Even if fuel prices go back to $30 per barrel (yeah, right), the improved fuel economy of winglet equipped airplanes will still be better than like types without winglets.

I dont believe the ex TWA birds will see winglets as they are due to come off lease between 2007-2009. In 2007 alone 15 subject to return.
Also the return on investment is not 6-12mos, its more like 2-3 years even with fuel at $60+. You need to keep in mind the cost associated with the modification including the two or so weeks in lost of productivity.
One last point to make, the TW B757s are not fully being maintained by AA as the RR fleet, they have instead been contracted out to Delta. If AA had a long term vision for the birds it would be cheaper to bring them inhouse already. As this has yet to happen I doubt AA looks at these 757s being core members of the fleet.

They would be much more likely than NW or UA. Though I reckon, given that AY will start holiday flights with techstops to places such as PTY, and since they do already fly PW 757s transatlantically, they could be a prime candidate for a winglet retrofit. I recall they extended the leases on their 757s, so that's a possibility. And if AY gets a few of those ex TW 757s that are still not allocated, then there's still hope for one of them getting the APB winglets after all.

I was in TUL last week at AA M&E and there were several ex-TW 757's in the hangar for heavy maintenance c-checks. The only maintenance DL is doing for AA on these aircraft is the heavy in shop engine maintenance. Likewise, AA handles the heavy maintenance on the DL 777 RR Trent 892 engines at the TAESL facility in AFW.
