Thanks. What does the "P" stand for, because when I look at "Flytecomm.com" it doesn't put the "P" in front. It is listed as "ANC".
What you are noticing is the difference between ICAO and IATA airport codes. The ICAO code is the international airport code as defined by ICAO and is four characters, while the IATA code is the three character airport code used by reservation systems with which the public is more familiar.
Airports beginning with P are pacific airports, while airports beginning with PA are Pacific Alaska-only airports. Airports beginning with K are airports found in the 48 contiguous United States.
