What does the airport code PHX stand for?
Phoenix
Pittsburgh
Philadelphia
Portland
The correct answer is: Phoenix
The airport code PHX stands for Phoenix, which is the capital city of Arizona. Airport codes use a three-letter system established by the International Civil Aviation Organization (ICAO) and the International Air Transport Association (IATA). PHX is the IATA code specifically assigned to Phoenix Sky Harbor International Airport. This is the primary airport serving the Phoenix metropolitan area and is one of the busiest airports in the United States. The other options represent cities and their respective airports but do not correspond to the code PHX: Pittsburgh is represented by PIT, Philadelphia by PHL, and Portland by PDX. Each of these cities has its own unique airport code that differentiates it from others.
