777 version question (lemmy.world)

Does someone know why Cathay Pacific and other airlines use different codes for airplanes than what Boeing has listed? For example they list a 777-367 which seems to be a variant of the 777-300 but I can't find any information on what makes it a 367 vs a 300. Is that just the code that CX uses for the 777-300s they own? I also notice they have odd ones like A321-251NX, A330-343X and such. So what do those non-normal model numbers mean?

Not sure where a list of all variations would be, but there may be something out there. Lots of companies can have similar subtypes, as fins change airlines frequently, be it by lease or sale. I flew the 767 for 4 years, and my company flight summary has about 6 different 767-300 variations broken down. We got our fins from all over the place, we had fins from Hawaiian to Ethiopian.
