why does delta have so many 2-letter codes for their registrations?

Why does delta have so many Reg # letter combinations! you can fit 1000 for each 2 letter designation (N000DL-N999DL) and i don't think they('ve) have/had that many planes!

That's an interesting question. I have asked that myself already, too. In fact, on the MD-88, you find very similar registrations: for example, there is as well N912DE AND N912DL.
You also find this at other US-carriers: For example:
- Northwest: NW, US, NB, etc.
- US Airways: US, UW, AU

And these are all planes that were originally delivered to the certain airline, no second-hand planes or planes that came to the airlines after mergers or acquisitions.

I have no idfea why this is like that.

As mentioned, some numbers have their roots in the former operator(s) of the aircraft.

That aside, the other main reason aircraft have different letters other than those expected is that the N-numner is already taken. For example, a desired N245DA might already have been assigned to another aircraft (GA or corporate, most likely), so they go for something similar line N245DX or whatever they can get. Doing so allows the airline to keep the N-number consistent with the aircraft's company "fleet" number (if that's what they want) used for various purposes.

I'm wanting to know the answer to the same question! Why do they have so many? Anyway, you're right about the "WA" registrations, they are ex-Western jets.

Here's some more 2 letter codes. There were a lot of different ones for the L-1011 fleet.

i think it was ex-ATA actually.

i could see lettering the L-1011's by former airline (well almost)

Dear Delta-

there is no M,H,N,Z,P,R or W in the word Delta.

Sincerely-
Billy, age 4.

US Airways and Northwest does that too. Northwest uses the US like US Airways does
