Which city code represents the Minneapolis-St. Paul airport?

The city code that represents the Minneapolis-St. Paul airport is MSP. This code is derived from the initials of the two cities, Minneapolis and St. Paul, which are located in Minnesota and are served by the Minneapolis-Saint Paul International Airport (MSP). Airport codes are often created based on the main city or cities served by the airport to facilitate identification and travel logistics.

In this case, MSP is officially recognized by international aviation organizations and is widely used for ticketing and baggage handling by airlines. This is a standard practice to designate airports, ensuring clarity and consistency across all airlines and travel-related services.

The other codes, while they belong to real airports, do not correspond to the Minneapolis-St. Paul area. RNO is the code for Reno-Tahoe International Airport in Nevada, TPA represents Tampa International Airport in Florida, and SNA stands for John Wayne Airport in Orange County, California. Thus, MSP is the correct answer as it specifically indicates the Minneapolis-St. Paul airport.
