Canceled or badly delayed at Houston Bush: get to a United desk - IAH is a United hub - and work the airline app while you stand in line. Skyway and TerminaLink connect the concourses inside security, Hobby is a 45-minute drive with an entirely second schedule, and if nothing works you are owed a full cash refund. Details below. Facts reviewed August 2026.
IAH is a United hub, and Skyway and TerminaLink connect the concourses. Any gate agent for your carrier can also rebook you - during a meltdown, a quiet gate's agent often beats the service-desk line. Work the airline app in parallel; whichever answers first wins.
The Skyway train connects the terminals inside security - never exit the secure area to reach another terminal. A realistic minimum connection at IAH is about 50 minutes; tighter than that and you should be asking an agent to protect you on the next flight now, not running.
Houston Hobby (HOU) is about a 45-minute drive. It is Southwest's field, an entirely second schedule across town. Booking a different airline does not burn your money: if your IAH flight was canceled and you do not travel on it, the unused ticket comes back as a refund or credit.
There is no rail at the airport - just a long rideshare into the city - so a train cannot replace a canceled flight in Houston. If your trip can flex, the honest alternatives are Hobby or driving.
Ask the airline what it covers before you book anything: most large US carriers commit to a hotel, or reimbursement, when an overnight disruption was in their control (mechanical, crew) - weather is usually on you. Lock in tomorrow's seat before hunting for a bed; seats vanish faster than rooms. Lounges if you hold access: United Club (B, C, E).
Canceled and you choose not to travel: a full cash refund to your original payment method under US DOT rules, on any fare type, whatever the cause - a voucher only replaces it if you knowingly accept one. Checked a bag? Here is exactly what happens to it and when the bag fee comes back. The full rundown with figures: Know Your Rights.
