What does the airport code DCA stand for?

The airport code DCA stands for Washington, D.C. (National Airport), formally known as Ronald Reagan Washington National Airport. This airport is located just across the Potomac River from downtown Washington, D.C., and serves as a primary airport for domestic flights into the capital. Knowing airport codes and their corresponding cities is essential for flight attendants as it helps in planning routes, understanding flight itineraries, and communicating effectively with passengers. The other options represent cities that have their own unique airport codes but are not associated with DCA, which is specifically designated for the National Airport in Washington, D.C.
