That's right. US Airways 757's were originally oparated by Eastern which selected the RR power plant. US and BA were the first two airlines to introduce the 757 almost 20 years ago, they both chose RR engines. Next was Delta, which was first to introduce the 757 with PW engines. More airlines choose RR engines because they generate more power than PW engines, 43000lbs vs 37000lbs of thrust. The reason Northwest and United chose PW engines is because they always had a strong relationship with that engine manufacturer. However, the advantage of the PW engine is its high-bypass ratio, which makes it a quiet engine.

American 767, the PW2000 series engines can put out more than 37,000lbs thrust, there is a version available for the new 757-300 that has 43,000lbs thrust that I believe NW has ordered. Go to the P&W website and check it out yourself.

You can also go to the seatmap of your flight where you picked your seat. If it starts with row 7 in Y you will have a PW powered one. If it starts with row 9, you will have a RR powered one. Go to seatguru.com and see the difference.

The AA 757's for the majority have RR engines. Only the TWA acquired ones have P&W. The nacelle of the engine on a RR continues all the way to the back (well, not necessarily the nacelle, but the grey and silver parts are flush on a RR). The P&W have a shape where the grey part of the nacelle ends and theres a space between the silver part (on the back).
Blah, I'm drinking, I dunno what I'm talking about. hope that helps.

To continue this, the TWA ones have a galley in the middle and no power ports in monkey class.

Quoting Delta767300ER (Reply 14): This is a bit off topic but a RR engine on a Boeing 757 sounds dull and like a buzzsaw. I would rather hear the P&W powerful whine. Thankfully all of Delta's Boeing 757's and P&W powered.
You may prefer the PW sound to the RR sound but rest assured it's likely to be a less powerful whine!

: You are correct about the -535C & -535E4. What did you use to reglue the RR Decal. regds MEL
: Wow, I didn't realize there were two different RR engine variants. Can anyone give a little more information on this? Thanks, UAL
