Specific Boeing Plane Types

Fri Oct 08, 1999 4:20 am

Hey everyone,
I was wondering what was with different plane types. For example, Delta has Boeing 757-232's, American B757-223, Britannia B757-236, Finnair B757-2Q8, etc. Are there any difference in these planes, or are they there because of an airline identifyer.

the addition on the end of plane types (like 757-2Q8) usually distinguish the type of engines that the airline has chosen. For example, Finnair's 757-2Q8 feature Pratt & Whitney PW2040 turbofan engines.

They are customer identifacations. Every single Boeing customer gets their own identifactation code. This is because every single customer has their own little differences this can range from engine choice to the color scheme in the lavs.

Some other airline codes are.

90- Alaska Airlines.
22-United Airlines.

Hope this helps

Actually, the two numbers/letters after an a/c type ex.)Q8, or say 32 refer only to the customer. Finnair's 757s are owned by ILFC, hence their Q8 designation. ILFC owns many 757s powered by RB211s, PW2037/40/43s all carry the Q8. All aircraft built for 1 company carry the same designation.
DL has 727-232s, 737-232/832...etc It has 767-332s in three different configurations...PW4056, CF6, and PW4060. All carry the same -332 or -332(ER) code.

Engine type has no relection on the code for Boeing aircraft. Airbus aircraft do however differ as the XX (A310-3XX) refers to the engine type. An A310-304 is GE powered while an A310-324 is PW powered.

There aren't any differences in them. The difference in numbers have to do with the Airline Identifier.

-21 was PanAm
-22 is United
-25 was Eastern
-31 is TWA
-32 is Delta
-33 is for American

That's basically a crash-course in aircraft Identifier's

33 is for American? I thought 33 was for Air Canada. I've got American as 23.

This topic has been discussed at least a couple of times. I suggest this webpage to learn the codes for each airline: BOEING'S CUSTOMER LIST. (263K!)

It's important to note that when the aircraft goes to a new operator, it retains the designation it came with. For example, N913AW of America West (G7) is a Boeing 757-225 originally delivered to Eastern. You have to be careful however, because there are exceptions. N506NA of National Airlines is a Boeing 757-236. Although 36 is the code associated with British Airways, this aircraft was originally built for and delivered to Air Europe. It never flew in BA colors. Also, aircraft with different customers codes are very likely to have variations in equipment and configuration, despite being the same type.

As FlyAA757 said, Airbus numbers its aircraft according to the engines.
Airbus A3XX

All Boeing 757's look the same when you watch them at a quick glance, but if you look at them more closely you will see that they are not always the same one from the other, the most distinctive feature is the power plant. The 757 is offered with 2 different engine types: Pratt & Whitney and Rolls Royce. The engine choice is up to each airline. If you see a nozzle coming out of the engine cowling, it's a Pratt & Whitney. If you don't see a nozzle coming out of the engine cowling, it's a Rolls Royce. American, British Airways, Continental and US Airways use them with Rolls Royce. Delta, Finnair, Northwest, United and TWA use them with Pratt & Whitney. Just to give you a few examples of who use them with which engine. Of course, the airline customer number (the last 2 digits) tells you right away who the aircraft is built for, but looking at the engine also helps you identify what airline it could be. A 757-223 with Pratt & Whitney engines, that does not exist, neither does a 757-232 with Rolls Royce engines. A 757-222 with Pratt & Whitney engines, that does exist.
DeltAirlines, a 757-236 is built for British Airways, not Britannia. A 757 built for Britannia would be a 757-204.

The other feature that could help you identify what airline the 757 belongs to is the seating layout although all 757's are arranged as follows: 2-2 in First and 3-3 in Coach like on all other narrowbody aircraft. But, the number of seats in First Class and Coach can vary from one airline to another, depending on how each customer wants to plan the aircraft. American has 22 seats in the First Class cabin on the 757.
