George Bush Intercontinental Airport (IAH) in Houston, Texas, is one of the busiest aviation hubs in the United States and a cornerstone of United Airlines’ domestic and international network. As United’s largest hub in the Southern United States and one of its most important global gateways, the airline operates primarily from Terminal C, Terminal E, and portions of Terminal B at IAH. For travelers flying through Houston, understanding the layout, amenities, services, and overall travel experience at United’s terminals can make a journey smoother, more enjoyable, and far more efficient.
United Airlines maintains a significant footprint at IAH. The United Airlines IAH Terminal serves as a major connecting point for flights across North America, Latin America, Europe, and Asia. As a result, United’s operations span multiple terminals, each with its own functions:
Terminal C is often considered the heart of United’s domestic operations at the airport and is known for its efficiency and traveler-friendly services.
Terminal E typically handles many of United’s long-haul international departures and arrivals.
Terminal B is used largely for United Express regional flights, featuring gates designed around quick turnarounds and commuter-style operations.
Because of this multi-terminal presence, passengers benefit from extensive connectivity as well as a wide range of amenities, lounges, shopping, and dining options tailored to both domestic and international travelers.
Terminal C is one of the busiest terminals at IAH and is almost entirely dedicated to United Airlines. Whether you’re flying to a major coastal city or connecting to a smaller regional destination, chances are you’ll pass through this terminal.
Terminal C features two main concourses—North and South—each connected by walkways and escalators. The layout is straightforward, designed to make gate-to-gate movement easy even during peak travel times. Clear signage, ample seating, and efficient security checkpoints contribute to a generally smooth passenger experience.
United offers multiple check-in options in Terminal C, including self-service kiosks, full-service counters, and dedicated Premier Access lanes for elite members and premium cabin passengers. Security lines move at a reasonable pace thanks to well-planned queue management and TSA PreCheck availability.
Terminal C has undergone renovations over the years, resulting in a mix of local Houston flavors and national brands. Travelers can enjoy everything from grab-and-go snacks to full-service dining featuring Tex-Mex, barbecue, and fresh market-style meals. Boutique stores, convenience shops, bookstores, and travel-accessory outlets also line the corridors.
Terminal C houses multiple United Club locations offering comfortable seating, workspaces, Wi-Fi, complimentary snacks, beverages, and quiet areas to unwind. These lounges are popular among frequent travelers and those with long layovers.
Terminal E is where United’s international operations shine. Serving as one of the airline’s key gateways to Europe, Asia, and Latin America, this terminal offers modern facilities geared toward long-haul travel.
Terminal E is known for its spacious design, high ceilings, and bright, open walkways. With wide corridors and modern architecture, it stands out as one of the most visually appealing terminals at IAH. Travelers connecting between Terminal C and Terminal E often remark on the seamlessness of the experience.
International travel requires expanded services beyond those offered in domestic terminals. Terminal E includes:
Currency exchange counters
Global Entry kiosks
Efficient international baggage claim and customs processing
Premium dining options
Duty-free shopping, ideal for those heading overseas or arriving from abroad
For eligible premium cabin passengers, United’s Polaris Lounge in Terminal E is a highlight. Known for elevated dining, high-end amenities, quiet suites for resting, and luxurious design, it represents one of the best lounge experiences offered by any U.S. airline.
Terminal B is dedicated largely to United Express operations. Many flights in and out of this terminal serve regional destinations, so the facilities here are built for efficiency and high volume.
The terminal features a unique layout with “piers” designed to accommodate a high number of regional jets. Covered walkways protect passengers from the elements, and the gate areas are organized to streamline boarding.
While Terminal B is not as modern as Terminals C or E, it still offers comfortable seating, essential dining options, and retail outlets for quick purchases. Travelers with connections to United Express flights often appreciate the proximity between gates and the ease of navigating the terminal’s compact design.
IAH provides an efficient inter-terminal transportation system that makes it easy for United passengers to move between the airline’s various terminals.
This underground train system connects all five terminals but is located outside of security. It’s ideal for passengers picking up or dropping off travelers or moving landside between terminal ticketing areas.
For connecting passengers, the Skyway is the primary transportation method. This elevated tram system is located inside the secure area and connects all terminals with quick, frequent service. It’s especially convenient for United travelers needing to transfer from a domestic flight in Terminal C to an international departure in Terminal E.
United’s hub operations at IAH offer an array of services that enhance the passenger experience:
Premier Access for elite members and premium cabin travelers
Self-service kiosks for faster check-in
Mobile app integration, offering digital boarding passes, flight updates, and baggage tracking
Family services, including stroller assistance and priority boarding
Accommodations for travelers with disabilities, ensuring accessibility throughout terminals
Staff presence is strong in United-operated terminals, making it easy to get assistance if needed.
IAH’s strategic location makes it ideal for connecting flights. Situated near the Gulf Coast, Houston offers favorable routing for travel to:
Latin America and the Caribbean
Major East and West Coast U.S. cities
Transatlantic and transpacific destinations
Global business centers, supported by Houston’s massive energy and medical industries
United’s heavy investment in IAH enhances its role as a premier global hub, giving travelers access to a vast network of destinations with efficient connection times.
