San FranciscO. Of course it's that airport IATA code
It does not mean. It's just the name of IATA organization for the Airports on the World
I was a Hawaiian travel agent and went to an Overpriced "travel agent school" on the original Spanish coastal trail, El Camino Real boulevard, and West Valley C.C. and CSM to learn 2 main PC languages back in the 80s. Fun but low pay and no benefits or even 1 "fam trip" tho the owner was SuperRich. It is interesting if you look online all the odd 3 letters combos for many cities. Only some are logical; Many you just have to memorize or constantly look up. One pet peeve was the official use by TAs of "direct flight" or "non stop", which is i thought was and is very misleading! There was ALOT for the Airlines and against the customer, even back in the 80s!
