The Houston–Las Vegas route
George Bush Intercontinental (IAH) to Harry Reid International (LAS) covers about 1,220 miles. Nonstop IAH–LAS is often on the schedule, about 3 hours airborne over 1,220 miles. This page is a US-market guide in USD — not a ticket and not a live calendar.
For IAH–LAS we show about $99 on the low end and around $175 as a more typical one-way economy total, USD, last reviewed August 2026. A $99 one-way is a sale-shaped guide, not a fare you can screenshot and demand. Taxes, bags, and seats change what you pay on the seller site.
Search IAH to LAS on Azurovia, compare airline-direct and travel-site totals on the same flights, then finish with the seller. We do not ticket. Keep their confirmation for changes.
Distance and time IAH–LAS
Great-circle distance IAH–LAS is about 1,220 miles. Block time on a nonstop is typically near 3 hours; wind, routing, and which runway you use still move the clock. Connections on the same city pair add layover time on top of that flying.
Las Vegas is about 2 hours behind Houston on standard time (America/Chicago vs America/Los_Angeles). Arrival clocks on LAS are local. That matters more on this pair than on a same-zone hop.
When IAH–LAS has a nonstop, that is usually the cleanest product. One-stop options still appear — they are worth opening only if the USD total is materially lower after you count the extra ground time.
Airports for Houston to Las Vegas
Both ends are in the United States: George Bush Intercontinental (IAH) to Harry Reid International (LAS). This is not an international itinerary, so the usual domestic bag and ID rules apply at the seller. Alternate metro airports can still beat this pair on price.
IAH is the only origin code we list in this metro. LAS is the arrival code we treat as primary for Las Vegas. A cheaper nearby airport only wins if the transfer still fits your plan. Search with “include nearby airports” when you want those codes in one results list.
