Not that this matters, but there is an unambiguous name for all the world's
airports, called the "ICAO name"(*). In the USA, it is always K..., so LAX
is "really" KLAX, and SBA is "really" KSBA.  European airports are L...,
Canadian ones are C..., etc.

The use of this name is rather specialized. (Filing international flight
plans, looking up airport weather observations and forecasts, etc.)

The three digit code is called the "IATA name"(**). It's almost always what
passengers talk about and what appears on luggage tags, but travel and
ticket agents have both names on their computers.

Some airports without pax service don't have IATA names.

I've never seen an airport within the USA where the ICAO and IATA names
differed by more than the K.

I've never seen an airport outside the USA where they did NOT differ
completely.

Occasionally within a region an airport acronym is used, even though it is
not at all like either of the actual airport codes. ("KCI", sigh.) Travel
and ticket agents presumably just silently correct this for people.
