Aircraft Types (i.e. 777-2__)

Sun Apr 23, 2006 12:40 am

Hey guys. Hope this is the right forum.

When a plane has its type listed here on the site, what do the last three numbers mean?

For example, a United Airlines 777 is 777-222. I know the first 2 is the -200 series, but what about the other two numbers? Is there a set system?

Another example is that both US and NW have their A330's listed as A330-323X.

Can anyone shed some light? And if there is a system, what is it?

As far as I know its just a number the aircraft manufacturer gives each airline so it can identify that airlines installed features.

Take British Airways for example. All their boeing aircraft end in "36" 747-436, 757-236, etc.

That makes sense, but then I find it odd that several airlines can have the same endings. (Like US and NW in the example I gave above). Unless they just have identical aircraft, and it makes it easier for the companies.

In Boeing Aircraft the the last two numbers, in your example the "22" represents the customer code. All airlines have their unique customer code applied by Boeing.

In Airbus aircraft the 2 letter codes aren't airline specific, but rather denote the type of engines/options the aircraft have.

Do a search on "customer code" in the civil, civil archived, and tech ops forums. You will find the answers.

Also, Boeing's customer codes are listed here:

Airbus, Boeing and Lockheed customer codes are on this site:

IIRC, Boeing customer codes are allocated when the aircraft is ordered. If then a particular aircraft is not taken up by the airline or leasing company it still carries the customer code for that airline or leasing company anyway.

Eg: VS 747-443's, these were initially ordered by Alitalia (code 43) but not taken up. VS then leased the aircraft.

This used to confuse the hell out of me when I first became interested in airliners. Hope it helps, if I am wrong on any of the above points, please correct me.  Wink

Confused me too, especially when I talked to an alleged "expert" who said the last two numbers had to do with the airfoil section being slightly different and I tried to corroborate that story for a while. It always bugs me when people don't know, but don't want to say they don't know. If you don't know, or you're guessing, just say so!

Great website. Lots of useful information. One other quick question about the Boeing codes.

What about an airline like Swissair, which doesn't exist anymore. Will their customer code get re-assigned or is it retired forever? Also, if LX orders any Boeing aircraft (which I doubt they'll ever do) would they adopt the old SR code?

They are retired for the most part. If you look at the boeing codes, you will see codes for Braniff, PanAm, Western, Eastern, Swissair, Sabena, etc. There are several cases where more than one airline had the same code, usually due to name changes. It is possible that if Swiss buys a Boeing, they might be assigned Swissair's code.

I think it very unlikely that Boeing would re-use the code of a now defunct carrier. Note that even with a company such as Tarom, their 707s were series -3K1Cs, while when they bought 737-700s they were 737-78Js - a new customer code. I think it's fair to say that when Boeing first introduced this system with the 707 and 720, they could not have foreseen the huge number of customers they would have in the future, and also how many of the then major carriers would "bite the dust" within a decade or two!
