How to Find the Cheapest Houston–Las Vegas Fares
01
Book 4–6 Weeks Ahead
Fares on this route tend to be lowest a month or more out, especially before major convention weeks.
02
Fly Tuesday or Wednesday

Compare Hobby and Bush Intercontinental
Southwest’s Hobby fares and Spirit/Frontier’s Bush Intercontinental fares can differ significantly — check both airports before booking.

Bundle Flight + Hotel
Package deals combining airfare with a Strip resort often undercut booking each piece separately, especially outside peak convention dates.
