410 destinations without changing, across 79 countries, from George Bush Intercontinental Airport. Flight times below are estimated from distance — no airline publishes a machine-readable block time — and the 90 minutes of getting to and through an airport are drawn separately rather than folded into a total.
Every destination reachable non-stop. The solid bar is time in the air; the pale one is the 90 minutes of airport at either end, counted once. Both are estimates.
Our records for flights from IAH were read on 11 August 2026 and describe the network as it ran that week. We hold no month-by-month variation, so this page cannot tell you whether a crossing runs in February.
If you are travelling well outside August 2026, confirm with the operator before you plan around it.
Flight times are derived, not published: great-circle distance at 800 km/h plus thirty minutes. They are honest about being estimates and they are not a schedule.
No fares, no departure times. Not for any airport, not for any airline.
Airlines on 146 of 410. The carrier list is 2014-vintage and names a carrier on 8% of the world's pairs; where it is silent the destination is still flown.
