Route Overview: Denver to Las Vegas
The flight path from Denver International Airport (DEN) to Harry Reid International Airport (LAS) is one of the busiest and most competitive corridors in the Western United States. Connecting the Mile High City to the Entertainment Capital of the World, this route serves millions of passengers annually, ranging from weekend vacationers and high-rollers to business professionals attending massive conventions at the Las Vegas Convention Center. Because both cities serve as major aviation hubs, travelers can benefit from high frequency and competitive pricing.

It is important to note that prices change daily based on demand, fuel costs, and seat availability.
Flight duration and schedule
A typical nonstop flight from Denver to Las Vegas takes approximately 1 hour and 55 minutes to 2 hours and 10 minutes of actual air time.

Flights depart as early as 6:00 AM and continue well past 11:00 PM, offering incredible flexibility. If you are looking for the best deals, call 1-800-518-9067 to speak with a specialist who can find the most efficient schedule for your needs.
Nonstop vs one-stop options
Given the short distance, the vast majority of travelers choose nonstop flights. However, during peak holiday periods or last-minute bookings, one-stop options through hubs like Phoenix (PHX) or Salt Lake City (SLC) may occasionally appear. These connecting flights can extend your travel time to 4 or 6 hours and are generally not recommended unless the price difference is substantial. Stick to the direct DEN to LAS route to maximize your time on the Strip.
Distance and typical aircraft
The great circle distance between Denver and Las Vegas is approximately 607 miles. This short hop is primarily serviced by narrow-body aircraft. You will most frequently fly on the Boeing 737 family (common with Southwest and United) or the Airbus A320 family (common with Frontier and United). These planes are optimized for quick turnarounds and efficient short-haul performance.
Airlines, Alliances and Aircraft on the DEN-LAS Route
Several major carriers dominate this route, ensuring that passengers have a variety of service levels to choose from. Whether you prefer a full-service experience or a no-frills budget seat, the Denver to Las Vegas market has it all.
United Airlines (Star Alliance)
United maintains a massive hub in Denver, offering numerous daily frequencies to Las Vegas. As a member of the Star Alliance, United provides seamless connectivity for international travelers. Their fleet on this route typically features Economy, Economy Plus, and First Class cabins. For those seeking cheap flights from Denver to Las Vegas, United often provides competitive basic economy fares, though these come with stricter baggage rules.
Southwest Airlines
Southwest is a dominant force at both DEN and LAS. Known for their unique boarding process and two free checked bags, they are a favorite for travelers who do not want to worry about hidden fees. They operate multiple flights an hour during peak times, making them the most flexible option for schedule changes.
Frontier Airlines
Headquartered in Denver, Frontier offers ultra-low-cost carrier (ULCC) service to Las Vegas. While their base fares are often the lowest in the market, they charge for everything from carry-on bags to seat assignments. This is an excellent choice for light packers looking for the absolute lowest DEN to LAS airfare.
Cabin classes and seat tips
On this 2-hour flight, seat selection can impact your comfort. If flying United, Economy Plus offers extra legroom which is helpful if you are tall. On Southwest, there are no assigned seats, so checking in exactly 24 hours in advance is crucial to securing an aisle or window. For the best views of the Rocky Mountains and the Grand Canyon (visible on clear days), try to sit on the left side of the aircraft when flying westbound from Denver.
Departure Airport Guide: DEN
Denver International Airport is famous for its iconic white peaked roof, resembling the snow-capped mountains. It is one of the largest airports by land area in the world, so allow plenty of time for transit.
Terminals and check-in
DEN consists of the Jeppesen Terminal, where check-in and security are located, and three airside concourses: A, B, and C. United Airlines primarily operates out of Concourse B, while Southwest is centered in Concourse C. Frontier and other carriers typically use Concourse A. You can reach the concourses via the automated train system located after the security checkpoints.
Getting to the airport
The most convenient way to reach DEN from downtown is the A Line commuter rail, which runs from Union Station every 15 minutes during peak hours. The journey takes about 37 minutes and costs approximately $10.50. If you are driving, the airport is located about 25 miles northeast of downtown Denver via I-70 and Pena Boulevard.
Parking and rideshare pickup
DEN offers several parking options, including the Garage (closest but most expensive), Economy lots, and the Shuttle lots (Pikes Peak and Mt. Elbert). Rideshare services like Uber and Lyft pick up on Level 5 of the Jeppesen Terminal, specifically at Island 5. Ensure you check which side of the terminal (East or West) your airline is located on to minimize walking.
Arrival Airport Guide: LAS
Arriving at Harry Reid International Airport is an experience in itself, with slot machines greeting you the moment you step off the jet bridge.
Terminals and baggage claim
LAS has two main passenger terminals: Terminal 1 and Terminal 3. Southwest and United typically arrive at Terminal 1, while Frontier often uses Terminal 3. Note that these terminals are not physically connected behind security, so ensure your ground transport knows which terminal you are arriving at. Baggage claim is located on the lower level of each terminal.
Ground transportation into the city
The Las Vegas Strip is only about 2 to 5 miles from the airport, making for a very short commute. Taxis use a flat-rate zone system to the Strip, typically ranging from $20 to $30. Rideshares have designated pickup zones in the parking garages (Level 2 in Terminal 1 and Valet Level in Terminal 3). For a budget-friendly option, the RTC bus system serves the airport, though it is less convenient with heavy luggage.
Cheapest Time to Fly and Fare Trends
Timing is everything when booking flights from Denver to Las Vegas. Because Vegas is a leisure-heavy destination, weekends and major holidays see significant price spikes.
Best days and months to book
Generally, Tuesday and Wednesday are the cheapest days to fly. Mid-week travel can often save you 30-50% compared to Friday afternoon departures. The cheapest months are usually January, February, and August, when the weather is either at its coldest or most extreme heat, leading to lower hotel and flight demand.
Typical fare ranges by season
| Season | Typical one-way fare | Notes |

Baggage Information and Fees
Baggage policies vary significantly between carriers on the DEN to LAS route. Always check your specific fare class before heading to the airport.
| Airline | Carry-on | First checked bag | Second checked bag |
|---|---|---|---|
| United | Included (except Basic) | $35 - $40 | $45 - $50 |
| Southwest | Included | Free | Free |
| Frontier | $50+ (varies) | $55+ (varies) | $70+ (varies) |
| Delta | Included | $35 | $45 |
How to avoid baggage fees
The easiest way to avoid fees is to fly Southwest Airlines, which remains the only major carrier offering two free checked bags. If you fly United or Frontier, consider using a co-branded credit card that offers free checked luggage or packing everything into a personal item that fits under the seat. Always prepay for bags online, as airport counter fees are significantly higher.
Weather in Las Vegas Through the Seasons
Las Vegas is located in the Mojave Desert, meaning it is dry year-round, but temperatures vary wildly.

Best months to visit
For the best balance of weather and price, April, May, September, and October are ideal. During these months, you can enjoy the famous Las Vegas day clubs and outdoor dining without the oppressive heat of July or the surprisingly cold winds of December.
Where to Stay in Las Vegas
Choosing the right neighborhood depends on your goals for the trip.
The Las Vegas Strip

Downtown Las Vegas (Fremont Street)
For a more vintage feel and often lower hotel rates, Downtown is the place to be. The Fremont Street Experience offers a massive LED canopy, zip-lining, and lower-minimum gambling tables compared to the Strip.

Beyond the gambling, Las Vegas is a global hub for entertainment. Major events like the Formula 1 Las Vegas Grand Prix in November and the Super Bowl have transformed the city into a sports mecca. Music lovers flock to the Sphere for immersive concerts or catch long-running residencies from superstars like Adele or Usher. Foodies will find the highest concentration of Michelin-starred chefs in the country. For those looking for nature, a short drive leads to Red Rock Canyon or the Hoover Dam.
