That's the good thing about healthy competition. Rolls are forced to stay on top of their game because GE are on top of theirs.
Two remarkable companies! AL |
N620DL out of the DL fleet
N620DL (msn 22910) is presently at Cecil Field, NAS (NZC) undergoing conversion to 757PF to be operated by FedEx.

A UPS Dispatcher here. I see the fuel burn numbers everyday with Pratts and Rolls on my desk and the Rolls burn more. More than a few times I'll have a SDF-west coast flight swap from one engine type to another and occasionally I'll get a call questioning the fuel burn. CI555 to the coast on an average plan and the burn difference depending on the PH of the stratosphere (kidding!) may be as high as 4,000 pounds. Just an observation from the sidelines here, not entering a debate on which is the better engine.
Regards, CV-880:D |

I believe your right, some, but not all of our 757s had a weird designator i.e. 2Q8. however, most of TWA's customer package was -31 or -231.
For example, our backwards wired 727-200s were 727-231 Adv. and I believe some of or 757s were 757-231. Good piece of trivia, Clamp. |

The last 2 digits of the Boeing designations is a customer code. i.e. 31-TWA, 22-UAL, 23-AAL, 32-DAL and many many more. That is why UA aircraft will often be shown as a B757-222, B767-222, B767-322, B747-422 etc. You can tell when a carrier has acquired a second hand aircraft or another carrier's delievery slot by comparing the last 2 digits.
I bet you learned that on Airliners.net. |

This may be true. According to DAL's page on APC, they're looking to simplify their fleet to four a/c type. Which one's they are....I don't know.
