With express train service, Stansted is convenient to London’s growing financial and business districts.

American plans to switch one of its two daily DFW roundtrips to London Heathrow, while the other DFW roundtrip will retain its current service to London Gatwick. American’s one daily Raleigh/Durham-to-London flight will also switch to Heathrow from Gatwick. The airline’s DFW-to-London service to both Heathrow and Gatwick will continue to be flown with three-class (First, Business and Economy/Coach) Boeing 777 aircraft with 245 seats. American’s Raleigh/Durham service will also continue to be flown with Boeing 777 aircraft. American’s JFK-Stansted service will be flown with two-class (Business and Economy/Coach) Boeing 767-300 aircraft with 221 seats, including 30 Next Generation Business Class seats.

I believe they are trying to take some MAXJet business away, so it would not make any sense to downgrade this route to a 757.
