Cheap Flights from Houston
Route-by-route flight guides for Houston travelers \u2014 which airlines fly each route, when to book, how to pay less, and what to sort before you go. Built for the way Houstonians actually travel, from Detty December Lagos trips to shoulder-season Europe.
IAH vs Hobby: which Houston airport?
George Bush Intercontinental (IAH)
Houston\u2019s long-haul gateway and United hub. Every international route in these guides \u2014 Lagos, Cancun, London, Paris, Rome \u2014 departs from IAH. More frequencies, more rebooking options when things go wrong, and the only choice for Africa and Europe.
William P. Hobby (HOU)
Southwest\u2019s Houston stronghold plus Spirit and Frontier. Frequently the cheapest all-in option for domestic and short-haul international (Cancun, Orlando) once Southwest\u2019s two free checked bags are factored in. Smaller, faster to navigate, easier parking.
Rule of thumb: compare both airports on every trip. They have different airlines, different fee structures, and often meaningfully different total prices.
Route guides
Houston to Lagos Flights
Typically 15–20 hours including one stop

About 9 hours eastbound, 10.5 hours westbound nonstop

Read the guide →Houston to Rome Flights
About 10.5–11 hours nonstop when operating

Read the guide →How Houston travelers pay less
- Compare connecting cities, not just dates. On long-haul routes like Houston\u2013Lagos, the connecting city (Istanbul vs London vs Doha) moves the fare more than shifting by a day.
- Tuesday/Wednesday departures price lower on average across nearly every route in these guides.
- Book peak travel absurdly early. Christmas, spring break, and Detty December reward 3\u20136 month advance booking; procrastination is the most expensive strategy.
- Do the baggage math. Southwest\u2019s two free bags and ULCC bag fees flip the \u201Ccheapest fare\u201D ranking constantly \u2014 compare totals, not headlines.
- Set fare alerts 3+ months out on the routes you actually fly, and pounce when the price dips rather than trying to time the absolute bottom.
