Houston is big. Really big. If you've ever flown through George Bush Intercontinental Airport (IAH), you know that scale isn't just a Texas cliché—it’s the reality of navigating one of the most complex aviation hubs in the Western Hemisphere. United Airlines basically owns this place. Well, not literally, but as their premier gateway to Latin America and a massive domestic engine, United’s footprint at IAH is staggering.
You’ll see the blue globe everywhere.
For the uninitiated, landing at IAH on a United flight can feel like stepping into a small city where the only language spoken is "connection times." It’s a beast. But if you know how the terminal logic works, you can actually have a decent time. Honestly, most people hate connecting here because they don't realize how the terminal layout actually functions. They see five terminals and panic.
Navigating the United Kingdom of IAH
United operates primarily out of Terminals B, C, and E.
Terminal C is the soul of the operation. It’s where the "Legacy Continental" vibes still linger, though it’s been modernized significantly. If you’re flying a standard domestic mainline flight, there’s a high probability you’re hanging out in C. Then there’s Terminal E. That’s the international powerhouse. If you are heading to São Paulo, London, or Tokyo, you’re walking those long, carpeted hallways in E.
Wait, don’t forget Terminal B.
Terminal B is where the United Express regional jets live. You know, the smaller planes where you have to valet your carry-on bag at the jet bridge? That’s B. The walk from the far end of Terminal B to the far end of Terminal E is... let’s just call it a workout. It can take 20 minutes if you’re booking it. Fortunately, the Skyway (the airside automated people mover) is a lifesaver. It stays inside the security perimeter, which is the most important thing to remember.
Do not go landside.

If you exit security to take the subterranean train (the one with the quirky 1960s Disney-style vibe), you have to go through TSA again. Everyone makes that mistake once. Don't be that person. Stay upstairs on the Skyway.
The United Club Situation: Where to Actually Hide
IAH has a lot of United Clubs. Like, a lot. But they are definitely not created equal.
The Terminal E club is usually the flagship experience, featuring expansive views of the tarmac and enough seating to actually find a corner for yourself. It’s massive. However, if you have access, the United Polaris Lounge (also in Terminal E) is the real gold standard. It is strictly for long-haul international business class passengers. You can’t buy your way in with a credit card pass. If you get in, go straight to the dining room and order a proper sit-down meal. It's miles better than the buffet.
Back in Terminal C, the North and South clubs are "fine." They’re reliable. They have those little automated coffee machines that make a surprisingly aggressive espresso. But they get crowded. Fast. Around 4:00 PM, when the evening bank of flights starts prepping, finding a chair in Terminal C South is like playing musical chairs with 400 other people in business casual.
If you want a quieter vibe, Terminal B has a club. Because it’s mostly regional flights, people often overlook it. It’s smaller, sure, but it’s frequently less chaotic than the main hubs in C.
Eating Your Way Through a Layover
Let’s be real: United Airlines George Bush Intercontinental Airport food has gotten way better over the last five years. OTG (the hospitality group) dumped a ton of money into Terminal C. Now, instead of just sad pre-packaged sandwiches, you’ve got iPads everywhere and actual local flavors.
- Pala: In Terminal C, the pizza is actually decent. It’s thin-crust, fired quickly.
- Bam Bam: If you want that Houston Viet-Cajun vibe, this is your spot in Terminal C. The shrimp is legit.
- Hugo’s Cocina: Located in Terminal D (but walkable from E), this is an offshoot of Hugo Ortega’s legendary Houston Mexican cuisine. Get the breakfast items if you're there early.
The weirdest thing about IAH? The pricing. It’s airport pricing, obviously, but Houston takes pride in its food scene, so the quality stays higher than you’d expect for a captive audience. Just watch out for those iPad service fees; they add up.

The Logistics of the "United Bank"
United runs a "bank" system at IAH. This means they schedule dozens of arrivals to land within a 45-minute window, followed by a massive wave of departures an hour later.
This is why the airport feels like a ghost town at 10:00 AM and a mosh pit at 2:00 PM.
If you are booking a flight, try to look at your connection time. 45 minutes is "legal" at IAH, but it is risky. If your arrival gate is at the end of Terminal B and your departure is at the end of Terminal E, you are going to be sprinting. I’ve seen it happen a thousand times. A one-hour connection is the "sweet spot" where you can grab a coffee and use a restroom without fearing for your life.
Also, Houston weather is a factor. Thunderstorms roll in off the Gulf of Mexico with zero warning. Because United has such a massive concentration of planes here, a one-hour ground stop can ripple through their entire network for twelve hours. If you see clouds turning that weird bruised-purple color over the airfield, check your United app immediately.
Technology and Efficiency at IAH
United has leaned heavily into the "Touchless" experience at IAH. There are dozens of self-service kiosks for bag tags. They’ve also integrated biometric boarding at many of the international gates in Terminal E. Basically, your face is your passport for the boarding process. It’s fast. Sorta creepy if you think about it too long, but fast.
The United app is actually your best friend here. It shows you a "wayfinding" map that gives you turn-by-turn directions between terminals. It even tells you how long the Skyway ride will take. In an airport this size, that data is more valuable than a gold-plated upgrade.
The Secret of Terminal A
Wait, does United use Terminal A? Technically, yes.

While A is mostly for other carriers like Delta, American, and JetBlue, United uses a few gates there for specific domestic routes. If you see "Terminal A" on your United boarding pass, do not panic. You can still use the Skyway to get there from the other terminals. It just feels a bit like you’ve wandered into a different airport because the branding changes. It’s often much quieter, though the food options are a bit more "old-school airport food" compared to the fancy Terminal C setups.
Misconceptions About IAH
People often confuse IAH with Hobby (HOU). Don't do that.
Hobby is on the south side of Houston and is basically a Southwest Airlines fortress. IAH is on the north side. They are about 30 to 45 miles apart depending on how bad the I-45 traffic is (and it’s always bad). If you book a flight into IAH and out of HOU, you’re going to need a miracle and a very expensive Uber.
Another misconception: "I can walk between all terminals."
You can, but you shouldn't. The walk from B to E is roughly a mile. If you have kids or heavy bags, the Skyway isn't a luxury; it's a necessity.
Actionable Tips for the Savvy Traveler
If you want to survive United's Houston hub like a pro, follow these specific steps:
- Download the Map: Open the United app before you land and look at the "Terminal Guide." Identify your arrival gate and departure gate immediately.
- The Skyway is King: Use the elevated train for any terminal transfer. The underground train is for people who have already cleared security or are heading to baggage claim.
- Check the "Club Fly" Concept: In Terminal B, United introduced a "grab-and-go" club concept. If you have a membership but no time to sit, you can just scan in, grab a high-quality sandwich and a drink, and leave. It’s a game-changer for tight connections.
- Avoid the Terminal C Security Lines: If you are checking in at IAH and the Terminal C North security line is backed up to the street, head over to Terminal E or Terminal C South. They all connect airside, and sometimes the wait times vary by 20+ minutes.
- Water Stations: IAH has decent bottle-filling stations near most restrooms in Terminals C and E. Don't pay $6 for a Dasani.
Houston is a powerhouse for United Airlines for a reason. It’s the bridge between the US heartland and the rest of the world. It’s big, it’s loud, and it’s humid, but if you treat it like a system to be navigated rather than a maze to be feared, it’s one of the most efficient hubs in the country. Just give yourself that extra 15 minutes of buffer time. You’ll thank me when you aren't sweating through your shirt trying to catch the last flight to Cancun.
