I noticed that all the majors except for CO have two letters as part of their registration at the end. American has AA and AN, Delta has DL, Northwest, has NW, United has UA, and US Airways has US. Why doesn't Continental have CO at the end like everyone else? They use six numbers instead of the typical three and two letters.

Actually, other airlines sometimes have three or four numbers plus only one letter, instead of two. And there are frequent exceptions to the general rules: many Northwest aircraft's registrations end in "US," and Delta has some ending with "DN," etc. It's even possible to have just one or two numbers, plus up to two letters (like the corporate jet of a certain athletic shoe manufacturer, which is registered N1KE). But I digress.
Anyway, it's true that Continental is unique among the major airlines in using only registrations that consist entirely of numbers. I don't know why they do it, but there is some logic to it: although the first two digits seem pretty much random, the last three digits are the fleet number.
All I know is that the randomness of those first two digits makes it a bitch to keep track of the registrations when preparing financing documents for several dozen CO aircraft at once, as I learned the hard way a few months ago...

Someone at Continental once told me that the registration numbers actually are in a code that will tell Scheduling and Planning what type of aircraft it is among other things. They track the 3rd digit.. N123456. All the aircraft in a type share the same 3rd digit. Just as an example........

I know your correct about the Connection carriers since the numbering system is used to track company aircraft. Continental and ExpressJet have no real say in the maintenance or specific use of Connection aircraft.

The last three digits are our internal ship numbers, kinda simplifies things for us as compared to United or Northwest with 4 digit fleet numbers in addition to registrations.
For example, if I was flying ship 058 tomorrow, that would mean I'm getting a 767-424ER, since they all are numbers 051-066 in the fleet, with registration N67058. The first two numbers have no relevance in the fleet, but sometimes are consistent within a fleet type, such as 764's N66051, N66056, N66057, etc..
Off the top of my head, here's what our fleet code breakdowns are:
001-050 earmarked for 777 above 018
051-099 earmarked for 764 above 066
8XX M80 (except 851-855 currently for 757-300, 738 deliveries over 299 will go in 8XX category)
(By the way, didn't see DeltAirline's post above, he hit it right on the nose, sorry for redundancy)

You're right on too, sorry if I made you feel bad!
A300s were 9XX series
727-100s were 4XX series
727-200s were 7XX series
737-100/200s were 2XX series
747s were ships 001 to roughly 025
DC-9-30 were 5XX series
DC-9-50 were briefly 6XX series
DC-10-30s were mostly 060-099
DC-10-10s that we originally operated were 040 to 059
Some DC-10-10s that we picked up over the years went into the 060-099 category though

I knew the last 3 digits were the fleet number, as I mentioned before, and I know the first digit of the fleet number (i.e. the third digit of the reg) depends on the type of plane, but what I have always wondered is how the first two digits are decided. They seem to be completely random, and it's very annoying when dealing with a long list of CO regs!

AA also has some 'TW' registrations.
NW also has 'NB' on their A319s.
They used to have 'US' on the DC-10-40.
There were some ending in 'E' and 'EA' from Eastern on 727s and DC-9s
'RC' are from planes out of the Republic fleet, primarily DC-9
'MC' on more DC-9s
I'm sure there are tens of different reg. styles for the nines, but these are some of the main ones.
