Delta Terminal IAH: Departures
Delta passengers departing from Houston should generally go to Terminal A for check-in and security.
Terminal A has north and south departure areas, with gates located throughout the terminal. Because gate assignments can change according to the day’s operation, your Delta boarding pass or Fly Delta app should be treated as the final source for your individual gate.
If you are searching terminal Delta IAH because you are heading to the airport for a flight, it is a good idea to confirm your flight status before leaving home.
Delta Arrivals at IAH
Delta arrivals at IAH use Terminal A. After getting off the aircraft, follow signs for baggage claim if you have checked luggage.
IAH’s official baggage information states that passengers arriving on airlines other than United should go to Terminal A baggage claim.

Delta Airlines Terminal Houston IAH: Check-In
Delta passengers can use the airline’s check-in options before reaching the airport. Online and mobile check-in can make the airport process easier, particularly when you are traveling with carry-on luggage only.
At the airport, passengers may use Delta’s check-in facilities in Terminal A. Your exact counter or bag-drop location can change, so check the airport information screens and Delta app when you arrive.
If you need to check baggage, allow additional time before security. Airport queues can become longer during morning departure periods, weekends, holidays, and other busy travel periods.
IAH Delta Terminal and TSA Security
Terminal A has security checkpoints serving its departure areas. IAH currently operates multiple TSA checkpoints across the airport, and checkpoint operating hours vary by terminal and location. For example, the airport lists separate hours for Terminal A North and Terminal A South.
This means passengers should not assume that every checkpoint at IAH operates on exactly the same schedule.
If you have TSA PreCheck, look for the appropriate lane at the checkpoint serving your departure area. IAH also supports TSA PreCheck Touchless ID at selected checkpoints, including Terminal A-North, for eligible travelers with participating airlines. Delta is one of the participating airlines.
Can You Move Between IAH Terminals?
Yes. This is useful if you arrive at the wrong terminal, need to meet someone, or have a connection involving another terminal.
IAH has five passenger terminals: A, B, C, D and E. The airport provides two automated transportation systems:
- Skyway – an airside train for passengers who have already passed security.
- Subway – a landside train for passengers who are outside the secure area.
IAH’s visitor information also provides airport maps and transportation information to help passengers navigate between terminals.
If your Delta flight departs from Terminal A, however, there is usually no reason to travel to another terminal unless your itinerary specifically requires it.
Delta Gates at IAH
Terminal A has north and south concourses with multiple gates. Current terminal information identifies gates in the A1–A30 range, although not every gate is necessarily used by the same airline on every day.
Your specific Delta gate can change, even after you have arrived at the airport. Always check the departure monitors and your Delta app for the latest gate assignment.
This is especially important when searching for iah delta terminal information because the terminal and gate are two different things:
