LAS to DEN Flight Guide: Find Deals from Las Vegas to Denver

When preparing for your trip from Las Vegas to Denver, timing is everything; try to book your tickets at least three to four weeks in advance to secure the lowest fares from competitive carriers like Southwest, United, or Frontier. Remember that Denver’s weather can be notoriously unpredictable due to the high altitude, so even if it is 100 degrees in Nevada, you should pack versatile layers to accommodate the cooler evenings and potential snowfall in Colorado. Additionally, since Denver International Airport is located about 25 miles from the city center, consider taking the RTD A-Line commuter rail for a cost-effective and scenic $10.50 ride directly into Union Station. Finally, always check your gate assignments upon arrival at LAS, as the airport’s layout with multiple terminals and automated trams can be time-consuming during peak holiday hours.

Flight prices for the LAS to DEN route typically fluctuate based on the season and local events. Mid-week flights in late January and February often offer the most significant savings, as the post-holiday lull hits the travel market. Conversely, prices tend to peak during the summer months and throughout the ski season from December to March. Booking during the shoulder seasons of late spring or early autumn often provides a great balance between affordable airfare and pleasant weather in both destinations.
