Pro Tips
- IAH is far from downtown Houston (~25 miles) with no rail link — budget 45–60 minutes by rideshare during peak hours.
- United dominates IAH; if you're not flying United, you'll be in Terminal E, which is serviceable but not as well-equipped.
- The underground train between United's Terminals A, B, C, and D is fast — use it for connections rather than walking the full terminal length.
- Terminal D's international lounge options are among United's best, including the flagship Polaris Lounge.
- Houston weather is severe in spring and summer — afternoon thunderstorms cause ground stops regularly; book early-morning departures when possible.
- If driving, US-59 (Southwest Freeway) or I-45 North are the main routes; allow extra time during Houston's notoriously heavy rush hours.
- IAH has a strong set of direct routes to Central and South America — often a better choice than connecting through Miami or Dallas.
