Which airport code identifies Los Angeles, CA?

The airport code that identifies Los Angeles, CA is LAX, which stands for Los Angeles International Airport. This code is derived from the airport's name, with "LA" representing Los Angeles and the "X" serving as a unique identifier—common in the naming conventions for major airports. LAX is a widely recognized and significant hub for both domestic and international flights, making it an essential part of air travel in and out of the United States.

The other codes listed refer to different airports: MIA is the airport code for Miami International Airport in Florida, EWR represents Newark Liberty International Airport in New Jersey, and IAH is the code for George Bush Intercontinental Airport in Houston, Texas. Each of these codes is therefore associated with their respective cities and does not pertain to Los Angeles.
