Hey got a quick question , whats the difference between a 737-3H4 and 737-3Y0, a 737-5H4 and 737-5Y0, and the difference between a 737-7H4 and another type of -700 (I cant remember the other "sub series") Any help would be great.

The last 2 characters on the right are the airline (or purchaser, i.e. a lease company) customer code...
H4 is Southwest, thus, 2H4, 3H4, 5H4, and 7H4 are the various models that Southwest has obtained from Boeing over the years. If it's something other than an H4, the aircraft originally was acquired by someone else, and Southwest later acquired it. N798SW and N799SW are good examples, and several of our -300s are not H4s...

Oh, good to know, I never knew that. So a 737-3Y0 would be purchased from another company, I get it! I did know that about the fuselage lengths, how the 735 is the same length as the 732 and so on. Thanks for the info!
