On boeing aircraft, the first three numbers designate the model, i.e. 737, 767 etc. The next one after the - is the sub-model i.e.e 737-500 or 737-400. The next two show which airline the aircraft was originally made for. I'm not sure if this has a proper name or not. For example, Korean air is B5, BA is 36, Continental is 24.
What I would like to know (if anyone can tell me) is who (if anyone) originally used Y0? Many airlines operate a 7*7-*Y0 for example, 767-3Y0/ER (see pictures below). I'm guessing if there was an airline with this tag, it's an airline that has been dead for a few years now.

The Y0 customer code was for the GPA Group, which were a huge Irish leasing company that went bankrupt in the 1990s. Most of their aircraft were taken over by GECAS. There are many, many aircraft carrying the GPA customer code, mainly B737s.
