Route Overview: Denver to Phoenix
The journey from the Mile High City to the Valley of the Sun is one of the most popular corridors in the Western United States. Whether you are traveling for business, a golf getaway, or to visit family, cheap flights from Denver to Phoenix offer a quick transition from the Rockies to the Sonoran Desert. This route is characterized by high frequency, competitive pricing, and a short duration that makes even a weekend trip feasible. Travelers can find all the latest schedules and book their next adventure through all Faresterminal route guides.
Flight duration and schedule
A typical DEN to PHX nonstop flight takes approximately 1 hour and 55 minutes to 2 hours and 15 minutes. The actual time spent in the air is often closer to 90 minutes, with the remainder of the block time accounted for by taxiing at two of the nation\'s busiest airports. On any given day, there are dozens of departures starting as early as 5:00 AM and continuing until nearly midnight. This high frequency allows for maximum flexibility when planning your itinerary.
Nonstop vs one-stop options
Given the proximity of the two cities, nonstop flights are the standard. However, travelers looking for ultra-low fares or those booking last minute might occasionally see one-stop options through hubs like Las Vegas (LAS) or Salt Lake City (SLC). Unless there is a significant price difference, the nonstop flights from Denver to Phoenix are highly recommended to save nearly 3 to 4 hours of total travel time.

Distance and typical aircraft
The great circle distance between Denver International Airport and Phoenix Sky Harbor International Airport is roughly 602 miles. Most airlines deploy narrow-body jet aircraft on this route, such as the Boeing 737 family or the Airbus A320 series. These aircraft are well-suited for the short-haul mountain-to-desert hop, providing a stable and efficient flight experience.
Airlines, Alliances and Aircraft on the DEN-PHX Route
Several major carriers dominate this route, ensuring that prices remain competitive throughout the year. From full-service legacy carriers to budget-friendly options, travelers have a wide array of choices.
Southwest Airlines
Southwest is a major player on this route, offering the highest frequency of daily flights. Known for their two-free-checked-bags policy, they are a favorite for families and golfers heading to Phoenix. They primarily operate Boeing 737-700 and 737-800 aircraft.
United Airlines
As Denver is a massive hub for United, they provide seamless connectivity for passengers coming from the East Coast or Midwest. United operates multiple daily nonstops, often using Airbus A319 or Boeing 737 Max aircraft. They are a founding member of the Star Alliance, making this a great route for earning MileagePlus miles.
Frontier Airlines
Based in Denver, Frontier offers some of the lowest base fares on the market. For example, a live one-way Economy fare found today for 2026-10-30 is $156 on F9 (nonstop, about 2h 3m). Keep in mind that while the base fare is low, they charge for both carry-on and checked bags. Prices change daily based on demand and availability.
American Airlines
American Airlines also serves this route, frequently connecting their Phoenix hub with Denver. They offer a range of service classes and are a part of the Oneworld alliance. Their schedule is particularly robust for those needing to connect through Phoenix to Southern California or Mexico.
Cabin classes and seat tips
Most flights offer a two-class configuration: First Class and Main Cabin (Economy). United and American also offer \'Economy Plus\' or \'Main Cabin Extra\' which provide additional legroom. On the short 2-hour flight, a standard aisle or window seat is usually sufficient, but if you are flying Frontier or Southwest, remember that seating is either assigned for a fee or based on boarding groups respectively.
Departure Airport Guide: DEN
Denver International Airport (DEN), often referred to as DIA, is famous for its iconic white peaked roof resembling the snow-capped Rocky Mountains. It is one of the largest airports by land area in the world, so arriving early is essential.
Terminals and check-in
DEN has one main terminal, the Jeppesen Terminal, where check-in and baggage claim are located. After security, passengers take an automated train to one of three concourses: A, B, or C. United Airlines primarily operates out of Concourse B, while Southwest and Frontier are typically found in Concourse C. American Airlines usually operates from Concourse A.
Getting to the airport
The A-Line commuter rail is the most efficient way to reach DEN from downtown Denver. The train departs from Union Station and takes about 37 minutes. Many travelers also utilize the RTD bus system or private shuttle services from the suburbs.
Parking and rideshare pickup
DEN offers several parking options, including the Economy lots and the Pikes Peak shuttle lot. For those using Uber or Lyft, the pickup and drop-off zones are located on Level 5 of the Jeppesen Terminal, specifically on the terminal\'s east and west sides depending on the airline.
Arrival Airport Guide: PHX
Phoenix Sky Harbor International Airport (PHX) is known as America\'s Friendliest Airport. It is located just a few miles east of downtown Phoenix, making for a very short commute once you land.
Terminals and baggage claim
Sky Harbor currently operates two main terminals: Terminal 3 and Terminal 4. Southwest and American are the primary tenants of Terminal 4, while United, Frontier, and Delta operate out of Terminal 3. Both terminals feature modern amenities and efficient baggage claim areas located on the lower levels.
Ground transportation into the city
The PHX Sky Train connects the terminals to the Valley Metro Rail at the 44th St/Washington station, providing an easy link to downtown Phoenix, Tempe, and Mesa. Taxis and rideshares are readily available outside each terminal. If you are heading to Scottsdale, a rideshare is typically the fastest method, taking about 20-30 minutes depending on traffic.
Cheapest Time to Fly and Fare Trends
Understanding seasonal trends is key to finding cheap flights from Denver to Phoenix. While Phoenix is a winter hotspot, Denver travelers often head south to escape the snow.
Best days and months to book
Generally, booking at least 21 days in advance yields the best results. Tuesdays and Wednesdays are statistically the cheapest days to fly. Avoid Sunday afternoons and Monday mornings if you are looking for the absolute lowest fares. For personalized assistance with group bookings or complex dates, call 1-800-518-9067.

Baggage Information and Fees
Baggage policies vary significantly between carriers on this route. Always check the specific fare rules before purchasing.
| Airline | Carry-on | First checked bag | Second checked bag |
|---|---|---|---|
| Southwest | Free | Free | Free |
| United | Fee (Basic Eco) / Free | $35 - $40 | $45 - $50 |
| Frontier | Fee applies | Fee applies | Fee applies |
| American | Free | $35 - $40 | $45 - $50 |
How to avoid baggage fees

March is particularly popular due to MLB Spring Training, though this is also when hotel prices are at their peak.
Where to Stay in Phoenix
Phoenix is a sprawling metropolis, so choosing the right neighborhood is vital for your trip.
Downtown Phoenix
The urban core has seen a massive revitalization. It is home to the Phoenix Suns (Footprint Center) and the Arizona Diamondbacks (Chase Field). Stay here if you want easy access to the light rail, museums, and a vibrant nightlife scene.
Old Town Scottsdale
Located just east of Phoenix, this area is the hub for luxury shopping, high-end dining, and art galleries. It is the best place for those seeking a resort-style experience with plenty of walkable entertainment options.
Biltmore & Arcadia
These upscale neighborhoods offer a mix of historic charm and modern luxury. Nestled near Piestewa Peak, they provide excellent access to both hiking trails and some of the city\'s most acclaimed restaurants.
Events and Reasons to Visit Phoenix
Phoenix is a major hub for sports and culture. Each February, the city hosts the Waste Management Phoenix Open, the most-attended golf tournament in the world.

Travelers often search for other major US routes like New York to Los Angeles (JFK-LAX) or Chicago to Miami (ORD-MIA) when planning their seasonal travels, but the desert Southwest remains a top-tier domestic destination.
