Flights to Las Vegas from Phoenix: The Complete Decision Page
This page answers the whole question, not just the fare: which airport to leave from, which airlines actually fly nonstop right now, what the trip really costs, when to fly for the lowest price, and whether you should be driving instead. It works in both directions, since the flight home to Phoenix is the same decision in reverse.
The verdict in one paragraph
Fly from Sky Harbor if you want frequency: Southwest and American run this route like a bus line, about 1 hour 15 minutes in the air. If you live in the East Valley, Mesa Gateway's Allegiant and Frontier flights can beat the drive to PHX. And the drive itself is a genuine option here: about 300 miles and 5 hours, cheap for a car full of people, miserable as a Sunday return.
Your airports and the airlines that fly nonstop
| Airport | Nonstop airlines to LAS (Oct 2026) | Flight time | Notes |
|---|---|---|---|
| Phoenix Sky Harbor (PHX) | Southwest, American, Frontier | About 1h15 | An American hub and a Southwest base, so frequencies are high all day. The default choice for most of the Valley. |
| Phoenix-Mesa Gateway (AZA) | Allegiant, Frontier | About 1h15 | Allegiant's anchor airport in the region. Far fewer flights than PHX, sometimes only certain days of the week, but parking is easy and the fares can be the lowest in the market. |
Spirit flew Phoenix to Las Vegas until it ceased operations on May 2, 2026. Frontier now covers much of that low-fare role from both airports.

What fares actually look like
Kayak's route data (last 12 months, checked October 2026) puts typical PHX to Las Vegas roundtrips between $90 and $254, with the cheapest recent roundtrip spotted at $62. Airline averages tell the story of the route: Southwest averaged about $310 roundtrip and American about $298, while Frontier anchors the bottom of the market. From Mesa Gateway, Frontier roundtrips have been found from $57. The single biggest lever is timing: booking at least four weeks out saved roughly half versus last-minute prices in Kayak's data.
The cheapest days to fly
Tuesday is the cheapest departure day from Sky Harbor (about $117 average roundtrip in flexible-date data) and Sunday is the most expensive (about $272). That Sunday number is the story of this route: an enormous share of Phoenix flies home from Vegas on Sunday, and the airlines price it that way. Shifting the return to Monday morning is the easiest money-saving move on this page.
Fly or drive: the honest math
Phoenix to the Strip is about 300 miles via US-93 through Wickenburg and Kingman, roughly 4 hours 45 minutes to 5 hours without stops. Fuel on the research basis is about $36 one way, so a full car drives roundtrip for around $75 plus parking. Flying door to door from Sky Harbor runs about 3.5 hours. Verdict: for one or two travelers the plane wins on time and roughly ties on money at a typical fare; for three or more, or anyone combining Vegas with the Hoover Dam and Kingman stops, the drive is honest competition. The Sunday return drive regularly runs an hour longer than the way up.
The arrival playbook
Land at Harry Reid International (LAS) and you are ten minutes from the Strip, but the details decide whether arrival feels easy or expensive. Start with the Harry Reid airport guide for terminals, rideshare pickup locations and the rental car center shuttle. Then the getting around Las Vegas guide for the monorail, Deuce bus, rideshare surge patterns and when a rental car actually pays. If you are still choosing where to sleep, the Las Vegas hotels hub compares the Strip, downtown and off-Strip honestly, and the packing list keeps you out of the airport shops.
Flying home: Las Vegas to Phoenix
Everything above runs in reverse, with two Vegas twists. Sunday is the most expensive and most crowded departure day of the week at LAS, and in summer the last flights of the day carry the highest heat-delay risk; the first departure of the morning is the safest seat in July and August. Arrive at the airport earlier than feels necessary on event weekends, when security lines stretch with 50,000 other people leaving the same convention.
