I've noticed there are very few 757's that have the Pratt & Whitney engine option. What were the airlines that had P&W powered 757's? I'm new to Airliners.net so pardon me if this is a commonly answered question.

All of DL's have P&W -- and it is one of the largest fleets! They took the former TWA 752's from AA as they were oddballs in AA's RR powered fleet, and are not afraid to add PW powered 752's on an opportunistic basis


I love to fly, and it shows!

Delta of course, United pre-merger of course, and Air Force One 757 I think.

I never knew Air Italy had PW 757's. Any others? Or is that it.

From Boeing orders/deliveries data, original 757 customers with P&W engines (number of aircraft in parentheses):

Condor (17 752s; their 13 753s are R-R)
Delta (116)
Ethiopian (5)
Far Eastern Air Transport (Taiwan) (7)
ILFC (Leasing company) (38; also 44 R-R)
Northwest (72)
Shanghai Airlines (13)
TWA (14)
United (98)
UPS (first 35; last 40 are R-R)
USAF (4)
Uzbekistan Airlines (3)

That's 40% of all 757s built. I don't consider that "very few".

What about preformance numbers?? Also I have noticed that the RR engines are much louder that the P&W, they sound like old vacuums (figures) ... well at least on the ramp.

AA went with RR since they guaranteed enough t/o thrust to go MEX-ORD nonstop with a full load. At the time (80s), the P&W 2037 was having higher than advertised fuel burn as well, but I understand the maintenance costs for the Pratts are a bit lower. Of course, all of this was at one time, and things might have changed. It would be great to hear from someone who has flown both and worked on both.

I noticed this too. You really notice it working on the ramp. The P&W engines are much quieter. I've never flown on a RR 757 before. Can anyone verify if the RR's are also noisier in the cabin?

Somewhat louder by a few decibles. I noticed that the t/o was quieter than the RR. Because of the demand of the 757, it is common to find mixed engine fleets. ET flies three RR examples in addition to their PW birds. FX and UPS both fly PW and RR examples.

They always think the new guy doesn't know anything. As a new hire with less than a month at Delta, I was deep inside the bin of a MadDog when I heard a plane taking off. I yelled to my coworker at the belt loader 'American 757' and pointed in its direction. I gained quite a bit of 'ramp credibility' from that.

I personally loved the sound that the Pratt's have on the 757. I could always tell it was the plane I was going to work just by the sound it made taxi'ing down the ramp

It is not well known,but GE engines were originally offered on 757s.Americans original 757 order was to have been GE powered.A few others were a;so interested.When American cancelled their original order and trimed their original 767-200 order in the early 80s,Ge stopped development of the engine.

It's interesting you ask! I've actually made a video comparing the two and I agree that the RR's are much louder. Feel free to check it out!

25 SDF880 : We have both types here and pretty equally matched. The only thing that stands out to me a bit is the Pratt burns less fuel. Hour leg maybe 300 to 500
26 seabosdca : The performance differences can be summed up as follows: P&W: better fuel burn, better total maintenance costs, quieter RR: marginally better T/O
27 LH707330 : Early on the RR also had a huge MTBO advantage, the Pratts were really new at the time and needed more attention until they matured.
28 goosebayguy : One of the main reasons RR did so well on the 757 was an overall weight saving of 3 tons compared against the PW. Quite a substantial difference.
29 Yukon880 : Would a state of the art engine today, comparable in thrust to a 757's PW2000 or RB211, weigh significantly more or less?
30 RussianJet : Interesting. Not a huge difference from inside the cabin it would seem, at least on takeoff. The RR were slightly noisier, but not a great deal more.
31 KC135TopBoom : Correct, had GE develope an engine for the B-757 it would have been called the CF-6-32. It would have been developed from the CF-6-50 with a smaller

38 Ferroviarius : Good afternoon, were the Finnair 757s not P&Ws, too? Best, Ferroviarius
39 AY-MD11 : Finnair has P&W engines on the 757. Anyone else noticed that the IAE is lot quieter than CFM on the A32Xs?
40 TrnsWrld : The OP kind of made me laugh a little saying that he noticed there are "very few" PW powered 757's, When in reality a couple of the worlds largest air
41 VV701 : No. Yes. As you say N701TW to N703TW, N704X, N705TW to N713TW, N714P and N715TW to N727TW. So 27 in all.
42 lightsaber : A little history. Remember RR had *two* engine on the 757-200 where they bought all the early examples. The 757 was launched with the RB211-535C Pratt

47 akelley728 : Yes it is. These were the ones that were ordered by TWA. The rest were leased and came via ILFC. TWA birds: N705TW, N708TW, N711ZX, N714P, N715TW, N7
