What is the IATA code for Guadalajara's airport?

• A. MMGL
• B. GDL
• C. DEN
• D. ORD

Answer: (B)

IATA codes are the three-letter identifiers airlines and travel systems use for airports, mainly for tickets, baggage tags, and itineraries. Guadalajara’s main international airport is Miguel Hidalgo y Costilla International Airport, and its IATA code is GDL. That code comes from the city name, using the consonants G, D, and L, which makes it easy to recognize and remember.

Another type of code you might see is the ICAO code, which is MMGL for Guadalajara. ICAO codes are used by air traffic control and for flight planning and aren’t the codes shown on tickets. The other two codes you might have seen, DEN and ORD, belong to Denver and Chicago O’Hare, respectively, and aren’t related to Guadalajara.
