Frequently asked questions

What is the cheapest month to fly from Houston Hobby?
January, February and the late August window typically produce the cheapest HOU fares, especially on Southwest's domestic and Mexico routes. Flightmussy's 12-month fare heatmap surfaces the exact week each route bottoms out — particularly valuable since Google Flights does not show Southwest pricing.
Which airlines fly out of HOU?
Southwest dominates Hobby with the bulk of departures, joined by Delta on Atlanta and Salt Lake routes and JetBlue on Boston and New York services. International coverage includes Mexico, Costa Rica, Belize and several Caribbean destinations. Flightmussy compares every carrier in one search.
What's the difference between HOU and IAH?
Hobby (HOU) is the older inner-city airport heavily used by Southwest, while George Bush Intercontinental (IAH) is United's massive long-haul hub farther north. Flightmussy's multi-airport origin filter searches both airports together so you can see the full Houston-area pricing in one query.
How far is HOU from downtown Houston?
HOU sits roughly 10 km southeast of downtown Houston. METRO bus route 40 links the terminal to downtown in 35-40 minutes, and taxis or rideshares cover the trip in 15-25 minutes outside rush hour. Parking close to the terminal is easier here than at IAH.
