What does PDX stand for in airport codes?

PDX is the airport code for Portland International Airport, which serves the city of Portland, Oregon. In the context of airport codes, each code is unique and generally represents a specific geographic location, typically using three letters to identify the airport. The use of "PDX" is meaningful because it not only denotes the airport but also reflects the city it serves, as airport codes are often derived from the name of the city or the airport itself. Understanding airport codes is crucial for flight attendants, as they frequently refer to these codes in scheduling, ticketing, and navigating layovers.

In this case, the other locations and their respective airport codes do not correspond with PDX: Miami International Airport is represented by MIA, Kansas City International Airport by MCI, and Louis Armstrong New Orleans International Airport by MSY. This knowledge of airport codes is essential for effective communication in the airline industry.
