George Bush Intercontinental Airport (IAH) in Houston is a large, multi-terminal airport with five passenger terminals: IAH Terminal A, B, C, D (Mickey Leland International), and E.
The terminals are spread over a considerable footprint, but are well connected internally — so transferring between terminals is manageable for passengers.
Two automated train systems link all terminals:
The Skyway — an elevated people-mover inside the secure (airside) area, connecting Terminal A, B, C, D and E.
The Subway — an underground train that connects all terminals (A–E) and the on-airport hotel, outside security (landside).
The Skyway makes travel between distant terminals relatively quick — for example, moving from Terminal A to the Terminal D/E complex via Skyway takes about 4 minutes 15 seconds.
Because of this interconnectivity, IAH can operate efficiently even with many terminals — but travelers should still allow extra time if they have connecting flights involving different terminals.
Delta Air Lines at IAH primarily uses Terminal A for its flights — both for departures and arrivals.
Terminal A serves mainly domestic and short-haul flights (though not exclusively) operated by several carriers including Delta, along with other airlines.
Within Terminal A: there are two concourses — North and South — which together house gates A1 through A30. Delta flights are typically assigned within these gate groups.
Terminal A amenities include standard traveler facilities: check-in counters (and kiosks), security checkpoints, baggage-claim on arrival level, ground-transport access, shops, restaurants/food outlets, charging stations, restrooms, and more.
While Delta Airlines IAH Terminal is the default for Delta, there are cases when flights labeled as “Delta” (especially codeshare flights operated by partner airlines, or certain international/long-haul flights) might use other terminals — often the more international-oriented terminals like IAH Terminal D or even the Terminal D/E complex.
In those cases, be sure to carefully check your boarding pass or flight-status notice — terminal and gate assignments can vary depending on factors such as codeshare airline, flight type, or scheduling.
Officially, Delta does not maintain a dedicated “Delta Sky Club” lounge at IAH.
However — there is a premium lounge accessible to certain Delta passengers (those holding eligible membership cards) — the American Express Centurion Lounge, which is located in Terminal D near gate D6.
That means if your flight lands or departs from Terminal A (Delta’s usual terminal), and you don’t need to move terminals, you might not have immediate lounge access unless you transfer via Skyway/Subway to Terminal D — which may require extra time and planning.
Navigating IAH — Transfers, Layout and What Travelers Should Know
Because IAH is a large, multi-terminal airport, successful travel requires familiarity with how to move between terminals, and what to expect in terms of amenities, walking distances, and transfers. Here’s what to keep in mind:
If you're airside (already past security) — use the Skyway: It runs every ~2 minutes and connects all terminals; fastest way to transfer between terminals for connecting flights.
If you're landside (arriving, or needing to re-check baggage, or going to parking/hotel) — use the Subway: underground, free, connects all terminals & on-site hotel, runs every ~3 minutes (except roughly between 12:30 a.m.–3:30 a.m., when service is closed).
Within Terminal A: walking from security to most gates takes just a few minutes (even to the farthest gates
Because terminals are physically separate — and given security, check-in, or immigration (for international flights) — it’s wise to build in extra time for transfers. This is especially true if:
You arrive on one airline/terminal and depart on another.
You land on an international flight in Terminal D/E on a codeshare, but depart on Delta (or vice versa).
You need to access lounges in another terminal (e.g. Centurion Lounge in D) but fly from A (Delta origin).
Terminal A offers a full set of traveler conveniences: check-in counters, baggage claim, ground transport access, food & beverage outlets, duty-free and retail shops, charging-stations, restrooms, pet-relief areas, currency exchange, and more.
If transferring via Skyway/Subway, signs to terminals, gates, train stations etc. are clearly marked — which helps.
What to Do — Advice for Delta Passengers Flying via IAH
If you’re planning to fly with Delta through IAH (or connect via IAH), here are practical tips to make your journey smoother:
Always confirm terminal & gate on your boarding pass or flight-status app — while Delta usually uses Terminal A, codeshare/international flights may land/depart elsewhere.
Allow extra time for transfers, especially if you suspect a terminal change — at least 60–90 minutes for connections involving different terminals (or more, if international).
If you want lounge access and hold an eligible card, check if you must transfer to Terminal D for the lounge — and account for transfer time.
Use Skyway (after security) or Subway (before security or landside) to move between terminals — they’re frequent and free.
Keep comfortable walking shoes or arrive early — even within Terminal A or moving between terminals, there can be considerable walking depending on your gate, concourse, or transfer path.
Summary — What Delta at IAH Means for You
Delta Air Lines at IAH commonly uses Terminal A — which handles many domestic and short-haul flights.
For certain flights (international, codeshare, partner operations), Delta-branded flights may use other terminals (e.g. Terminal D/E), so always check terminal assignments.
Thanks to internal transit systems (Skyway — airside, Subway — landside), moving between terminals is fairly convenient, though requiring some time.
Terminal A offers full airport services — check-in, security, shops, dining, baggage-claim, and ground transport access — but Delta does not have a dedicated lounge there, so lounge access may require terminal change.
As a traveler, it’s wise to plan ahead, check your boarding pass carefully, and allow buffer time if your itinerary involves transfers across terminals or uses lounges in other terminals.
