Hi, I was wondering what the difference between a 747-400, 422, 438 ect.? What do those last two numbers mean?

the last two digit is customer code that boeing used to identify the orginal customer for the aircraft.

ex- -438 means its a 747-400 ordered by Qantas.

The last two numbers or letters are airline codes. Like AA's 757s are 757-223, 23 is the code for AA. UAL owns 747-422s, 22 is UA. And so on...

Boeing assigns two digit number to every airline that come right after the series. For example British Airways was assigned #36, so all the 747s are 747-136, -236, -336, or-436 and 757-236. You get the point.

In addition, when the aircraft changes owners, the designation stays the same. A 744 built as a -422 will always be a -422, no matter who owns it.

You obviously don't know your engines since you cried earlier about Continental flying 757's over to Europe.
CO's 757's use the Rolls Royce engines, and can fly for over 9hours. I guess you won't fly from sfo-ewr on 757's either. A Newark-Birmingham England flight is 6hours 20min, and a Newark-San francisco flight is 6 hours 10 min. So what is the difference?

Actually, there's a few exceptions. I remember a 747 ordered by Braniff and never delivered. The aircraft was buildt under the -27 Braniff Boeing code but was later delivered to another airline and converted to another Boeing's customer code.
