About flights from Houston (IAH)
George Bush Intercontinental sits 23 miles north of downtown Houston, which either tells you it was built when land was cheap or that Texans just think big. Probably both. IAH runs five terminals, handles United as its dominant carrier, and quietly punches out 193 direct routes across 39 countries — a reach score of 92 out of 99, which is genuinely impressive for a city that doesn't always get its travel credentials acknowledged. This isn't a connecting hub you endure. It's one worth flying to on purpose.

Why fly to Houston?
Houston's connectivity reflects what the city actually is: an energy industry capital, a medical research powerhouse, and one of the most demographically varied metros in the country. That last point matters at the airport. Twenty-four direct routes into Mexico alone mean you can reach Oaxaca, Monterrey, or the Yucatán without routing through Dallas or Miami like some kind of inconvenience. The longest route out of IAH stretches 13,835 kilometers all the way to Sydney on a United 787, which is the kind of single-ticket option that used to require a stopover in Los Angeles and half your sanity. British Airways, Air France, Avianca, and EVA Air all serve IAH, giving you genuine alliance competition on transatlantic and transpacific fares. That competition is worth watching when you're pricing out business class.

Tips for travelers at IAH
Don't assume a cab is your only ground option — the IAH Airport Express bus connects to the Houston METRORail system, which gets you into downtown without the $65 flat-rate taxi fare. If you're flying United (and statistically, you probably are), Terminal C is your home base and has the better lounge options. Summers in Houston are genuinely brutal, so building in buffer time for afternoon thunderstorms is smart — convective weather regularly causes ground delays between June and September. Arrive early, drink the air conditioning, appreciate that the airport has actual Texas barbecue if you look past the obvious fast food.
