Frontier Airlines Pre-Arrival Practice Test

The airport code that represents Detroit, MI, is DTW. This code is derived from the name of Detroit Metropolitan Wayne County Airport, which is the primary airport serving the Detroit area. Airport codes are often based on the first letters of the city's name or the airport's name, and DTW follows this convention by incorporating 'D' for Detroit and 'TW' from the airport's full name.

The other codes refer to different airports; for instance, MCI is the code for Kansas City International Airport, LAX is known for Los Angeles International Airport, and GEG represents Spokane International Airport. Understanding these codes is essential for identifying specific airports, especially when booking flights or navigating travel logistics.
