The Houston to Las Vegas route covers roughly 1,220 miles and takes about 3h 15m nonstop. 4 airlines compete on it — Southwest Airlines, United Airlines, Spirit Airlines, Frontier Airlines — which keeps fares moving and makes it worth comparing carriers rather than defaulting to the one you usually fly.

Las Vegas is one of the few destinations where the airport sits five minutes from the main attraction. The Strip delivers the casinos, the residencies and the buffets, and Fremont Street downtown delivers a cheaper, older, louder version of the same idea.
What surprises first-time visitors is what surrounds it: Red Rock Canyon is 20 minutes west, Hoover Dam is 40 minutes east, and the Grand Canyon is a legitimate day trip.
