Fly from IAH to LAS: Find the Best Deals on Houston to Las Vegas Flights

To secure the best rates, try booking your flight at least three weeks in advance, as last-minute prices often spike due to the high demand for weekend getaways in Nevada. Consider flying on a Tuesday or Wednesday; these mid-week departures are typically significantly cheaper than Friday or Sunday flights when the crowds surge for weekend events and conventions. If you are looking to save on transportation once you land, utilize the RTC Westcliff Airport Express or the Centennial Express bus services, which offer an affordable alternative to the often-congested taxi lines at the airport. Finally, remember that Las Vegas weather is desert-dry, so stay hydrated throughout your flight from the more humid Houston climate to avoid altitude and dehydration headaches while exploring the Strip.

Flight prices for the IAH to LAS route tend to fluctuate based on major events and temperatures. The most expensive times to fly are typically during the New Year’s Eve celebrations and major conventions like CES in January. Conversely, you can often find the cheapest fares during the scorching summer months of July and August or the mid-week periods in early December before the holiday rush begins. Always check the local event calendar, as prices can spike during high-profile residency launches or major sporting events at Allegiant Stadium.
