IAH vs Hobby (HOU): Which Houston Airport Should You Use?
Fares shown are modelled estimates, not live quotes.
Airport Breakdown
International flights to Europe, Latin America, and Asia. IAH is Houston's global hub with nonstop service to 50+ countries. United Airlines dominates here as a major hub carrier.
Domestic short-hauls under 2 hours and budget travel within the US Southeast. The airport is massive and parking/TSA lines can be brutal during peak hours.
Rideshare (Uber/Lyft) from downtown Houston costs $35-52 depending on surge pricing, 30-45 minutes. SuperShuttle ($28-35, 45-60 min). Rental car is viable if you're staying 3+ days. METRO bus 102 ($1.25, 60-75 min) departs every 20 minutes but luggage space is tight.
Book United award flights here 8-12 weeks out—their inventory is deepest and off-peak fares to Europe drop to $450-550 RT in shoulder season. Avoid connecting through IAH on non-United airlines; wait times are notoriously long due to hub congestion.
Domestic flights, especially Southeast routes. Southwest Airlines makes this their Texas hub with massive daily capacity. Faster security, shorter walks, no train transfers needed.
International travel beyond Mexico/Caribbean. Very limited international routes. International terminals are outdated and cramped.
Rideshare $28-38 from downtown, 20-30 minutes (closer location). SuperShuttle $22-28, 35-45 min. METRO bus 40 direct to downtown ($1.25, 40-55 min, runs every 15-20 min). No rental car needed for most travelers due to proximity.
If you're flying Southwest anywhere in North America, HOU fares are typically $50-100 cheaper than IAH because it's Southwest's preferred hub. Book HOU flights 6-8 weeks early when Southwest opens seats for major holidays.
Our Verdict
Use IAH for any international trip beyond Mexico/Caribbean or if you're flying United to Europe—nonstop options and hub pricing beat alternatives. Use HOU for all domestic flights, especially if you're on Southwest, and for quick beach trips to Cancun or the Caribbean—you'll save 20-30% on fares and skip the airport hassle. If you see identical pricing, HOU wins on convenience every time.
