This might be a stupid question to many of you but I've always wondered what the last two numbers in aircraft names mean and why so many planes that are the same model have so many different combinations of last two numbers. For example, the 772ER has versions like -223 -222 -236 -219 and so on.

They designate the customer.

Which is why calling a plane the 747-8 or 747-800 is meaningless, because the real name will be 747-8XX.

Boeing I think will drop the 00 from now on to be different than Airbus.

They'll call their planes the "747 dash 8" for example, which is a throwback to the 707 days of the "dash 80." The 787 is doing this with the dash 3, 8 and 9. The 797 will start with dash 2, 3, 4 and 5.

Of all the things to worry about... the Wookie has no pants.

So you're saying that all of United's 772ERs have the same last two numbers? Also, how are these numbers generated? And if they show customers, then how come they call it the A380-841 when its not for any real customer yet?

Yes, all UA 772s have the same customer code. Airbus designates their aircraft differently, and the last 2 digits designate the engine package rather than the customer.

BG777300ER - take a look at this site for the Boeing customer codes - http://www.airlinecodes.co.uk/ - select the Boeing Codes link.

I don't have a link for the Airbus engine codes, but the 1st digit is the manufacturer, and the 2nd digit is designates the type of engine offered by that manufacturer for that aircraft. I am pretty sure the first digit is allocated as follows:

0 - GE
1 - CFM
2 - PW
3 - IAE
4 - RR
5 - Engine Alliance

So for instance, a -311 and a -313 would both have CFM engines, but of different thrust ratings...
