Which city does the airport code MEM refer to?

The airport code MEM refers to Memphis, Tennessee, which is home to Memphis International Airport. Airport codes are typically derived from an abbreviation of the city or the airport’s name, and in this case, "MEM" clearly corresponds to "Memphis." Memphis International Airport is a significant hub, particularly for FedEx operations, which further solidifies its recognition associated with the city.

In contrast, the other options represent different cities with their own distinct airport codes. Miami, for example, is represented by MIA, while Myrtle Beach uses MYR, and Tulsa is designated by TUL. Understanding these codes is essential for flight attendants as they navigate various travel itineraries and assist passengers.
