Route Overview: Las Vegas to Denver
Flight duration and schedule
The journey from the neon lights of the Mojave Desert to the high-altitude peaks of the Rockies is one of the busiest corridors in the Western United States. When you book cheap flights from Las Vegas to Denver, you are looking at a very manageable time in the air. The average flight duration typically ranges from 1 hour and 45 minutes to 2 hours and 10 minutes. Because Denver is in the Mountain Time Zone and Las Vegas is in the Pacific Time Zone, travelers will lose one hour when heading east. Flights depart as early as 5:00 AM and continue late into the night, often with 'red-eye' options departing after 10:00 PM for those looking to maximize their time in either city.

Nonstop vs one-stop options
The LAS to DEN nonstop route is highly competitive, which is excellent news for your wallet. Major carriers and low-cost airlines provide dozens of daily direct flights. While nonstop is the standard, some travelers might find cheaper fares with a single stop in cities like Phoenix (PHX) or Salt Lake City (SLC). However, given that the direct flight is so short, a layover usually adds 3 to 5 hours to your total travel time, making the nonstop option the preferred choice for most business and leisure flyers. You can browse all available options on our all Faresterminal route guides page.
Distance and typical aircraft
The Great Circle distance between Harry Reid International Airport (LAS) and Denver International Airport (DEN) is approximately 602 miles. Because this is a high-frequency route, you will typically find narrow-body aircraft servicing the path. Common models include the Boeing 737 (frequently used by Southwest and United) and the Airbus A320 family (a staple for Frontier and Spirit). These aircraft are optimized for efficiency on short-to-medium haul domestic hops.
Airlines, Alliances and Aircraft on the LAS-DEN Route
Southwest Airlines
As the dominant carrier at LAS, Southwest Airlines offers the most frequent service to Denver. They are famous for their 'Bags Fly Free' policy and no change fees. Southwest operates out of Terminal 1, Concourse C and Terminal 3, Concourse E. Their 737 fleet provides a consistent experience, though they do not offer a traditional first-class cabin. A live one-way Economy fare found today for 2026-10-12 was $107 on WN (nonstop, about 2h 0m), though prices change daily.
United Airlines
United Airlines maintains a major hub at DEN, making this a vital 'spoke-to-hub' route. United offers multiple fare classes, including Basic Economy, Economy, and United First. Members of the Star Alliance can earn and redeem miles on this route. United typically operates from Terminal 3 at LAS.
Frontier Airlines
For those seeking the absolute lowest base fare, Frontier Airlines is a major player. Headquartered in Denver, Frontier offers ultra-low-cost service. Travelers should be aware that while the ticket price is low, fees apply for carry-on bags, checked bags, and seat assignments. It is a great option for light packers.
Cabin classes and seat tips
On this short flight, most aircraft feature a 3-3 seating configuration. If you are flying United, look for 'Economy Plus' for extra legroom. On Southwest, remember that seating is open; checking in exactly 24 hours in advance is crucial to securing an aisle or window seat. For Frontier, the 'Stretch' seating at the front of the plane offers significantly more pitch for a modest fee.
Departure Airport Guide: LAS
Terminals and check-in
Harry Reid International Airport (LAS) is unique for its proximity to the Las Vegas Strip. It consists of two main terminal buildings: Terminal 1 and Terminal 3. They are not physically connected, so knowing your airline is vital. Southwest and Spirit are usually in Terminal 1, while United, Frontier, and Delta are in Terminal 3. Check-in counters are usually busy, so arriving 2 hours early is recommended.
Getting to the airport
LAS is roughly 2 to 5 miles from most major Strip resorts. Taxis and rideshares are the most common methods of transport. If you are coming from Downtown Las Vegas, the RTC transit bus (Route 108 or the Wax) provides a budget-friendly alternative.
Parking and rideshare pickup
Rideshare pickups (Uber/Lyft) at LAS are located on Level 2 of the Terminal 1 parking garage and Valet Level of the Terminal 3 garage. For those driving, the long-term parking structures are well-marked, but they can fill up during holiday weekends or major conventions.
Arrival Airport Guide: DEN
Terminals and baggage claim
Denver International Airport (DEN) is famous for its peaked white roof, designed to mimic the Rocky Mountains. All flights arrive at one of three concourses (A, B, or C). All passengers then take an underground train to the Jeppesen Terminal for baggage claim and ground transportation. United typically uses Concourse B, while Southwest uses Concourse C.
Ground transportation into the city
DEN is located about 25 miles northeast of downtown. The most efficient way to reach the city center is the A Line commuter train, which runs every 15 minutes and takes you directly to Union Station in about 37 minutes. Taxis and rideshares are also available but can be expensive due to the distance.
