DIA Airport Code: Denver DEN vs Doha DIA Explained
“DIA airport code” is one of the easiest airport-code searches to misread. Denver locals say DIA, but the code on tickets and baggage tags is DEN. Doha adds another layer because travelers may see DIA in older or charter-related Qatar contexts while scheduled Doha passenger flights use DOH.
DIA is not the Denver airport code — DEN is
DIA is a widely used abbreviation for Denver International Airport. It is not the code you should type into an airline booking form if you want Denver. Use DEN for flights, baggage, airport search boxes, and airline apps.
The Denver ICAO code is KDEN. That code appears in aviation, weather, flight-tracking, and aeronautical contexts.
Airport live checks & travel tools
Use current local conditions, official live-status links and planning calculators before you travel. Airline gate, terminal and flight times can change; your carrier remains the final source for flight-specific details.
Live flight center
Check the airport's official flight board, then confirm any last-minute gate or timing change with the airline.
Current airport-area weather
Useful for planning your trip to the airport. This is model-based local weather, not an aviation METAR or an airline operational forecast.
Quick official checks
Open the source that matches the decision you are making right now.
When should I reach the airport?
A planning estimate based on flight type and common time buffers. Always increase the buffer for severe weather, major holidays, unusual airport alerts or airline instructions.
Connection-risk checker
This is a planning heuristic, not an airline minimum-connection-time rule. International arrivals that require U.S. entry processing, baggage claim and security can need substantially more time.
Parking cost estimator
Uses the airport-specific rates stored in this article's configuration. Rates can change; verify availability and final pricing on the official parking page before driving in.
Passenger pickup readiness
Landing time is not curb-ready time. Add time for taxiing, deplaning, baggage claim, customs when applicable and walking to the correct pickup zone.

Use 80249 for address context
The official airport address is 8500 Peña Blvd, Denver, Colorado 80249.
DIA airport code Doha: when the search query points to Qatar
Some people searching “DIA airport code Doha” are trying to separate Doha International Airport from Hamad International Airport. For normal scheduled passenger travel today, search and book Doha flights with DOH, which refers to Hamad International Airport.
Qatar aeronautical sources list OTHH for Hamad International and OTBD for Doha International. Doha International may appear in aviation, charter, or older-context searches, but it should not replace DOH when you are booking a typical passenger flight to Doha.
Scheduled Doha passenger flights
Use DOH for Hamad International Airport, Qatar Airways itineraries, Doha layovers, and most passenger travel searches.
Hamad International ICAO
Use OTHH for aviation and aerodrome references tied to Hamad International Airport.
Doha International ICAO
Use OTBD when the source specifically discusses Doha International Airport, not Hamad International.
DIA airport code departures: what to search
If you are looking for Denver departures, search DEN departures or use the official Denver International Airport departures page. Searching “DIA departures” usually works in search engines because DIA is a common nickname, but it is not the code used by airlines.
Denver = DEN. Doha scheduled passenger airport = DOH.
Search by flight number if possible. Airline apps often update before generic search results.
Gate, road, parking, and security details can change during the day.
At DEN, pickup, rideshare, taxi, and train access use different terminal levels and islands.
DEN travel decisions after you solve the DIA code problem
Most people do not only need the code. They need to know what to do next: check departures, choose transport, plan parking, or pick up a passenger without circling Peña Boulevard.
