Which airport uses the code DCA?

Denver
Atlanta
Washington DC
Kona, Hawaii

The correct answer is: Denver

The airport that uses the code DCA is actually in Washington, D.C., specifically Ronald Reagan Washington National Airport. This airport serves as a major hub for domestic flights and is located very close to downtown Washington, D.C., making it a convenient option for travelers heading to the capital. The other options do not correspond with the DCA code. Denver has a different airport code, which is DEN, while Atlanta's main airport, Hartsfield-Jackson Atlanta International Airport, is designated ATL. Kona, Hawaii, is served by an airport that has the code KOA. Each airport code is unique and helps identify the specific location efficiently for airlines and travelers.
