Alaska Airline City Codes Practice

The code for the airport located in Las Vegas is LAS, which stands for McCarran International Airport, its primary airport serving the Las Vegas area. Airport codes are typically derived from the name of the city or the airport itself, and in this case, "LAS" is a straightforward abbreviation for Las Vegas.

In contrast, LAX refers to Los Angeles International Airport, located in California, LGA stands for LaGuardia Airport in New York City, and LBJ is not a recognized airport code. Each of the other choices corresponds to different airports in different cities, which highlights why LAS is the only correct code for the Las Vegas airport.
