Which airport has IATA DEN and ICAO KDEN?

Understanding how IATA and ICAO codes relate helps you see why this match is correct. IATA codes are the 3-letter identifiers travelers encounter on tickets and baggage tags, while ICAO codes are the 4-letter identifiers used for flight operations and air traffic control. In the United States, many ICAO codes start with a K, followed by the airport’s typical IATA code, so Denver International Airport is KDEN in ICAO terms and DEN in IATA terms. Therefore, the combination DEN and KDEN refers to the same airport. The other options point to Dallas/Fort Worth (DFW/KDFW), Los Angeles (LAX/KLAX), and New York JFK (JFK/KJFK), which do not match DEN/KDEN.
