The Houston to Denver route at a glance
Houston Bush is a United hub, and Denver is another, with about 860 miles and roughly two and a quarter hours of flying time between them. Denver is one hour behind Houston, and Houston also has a second airport, Hobby, so it's worth checking which one actually matches your flight before you plan ground transportation. Denver's winter weather can occasionally affect connections through its hub, so a little extra buffer is sensible if you're continuing on from there in the colder months.
Tips for this route
- Ski season fills flights to Denver. Book early for winter weekends and school breaks.
- Gulf Coast storms in late summer can disrupt flights out of Houston. Build in some slack in August and September.
- Denver’s airport is far from downtown, so allow for the ride into the city.
