Secret to Getting a Cheap Flight Ticket From Denver (DEN) to Las Vegas (LAS)

about_img

The Denver to Las Vegas route is primarily used for vacationing, which is why the flight prices tend to be highest on the weekends, during the holiday season, and during major events in the Vegas region.

  • Instead of clicking through to each airline's website, search on a fare comparison website like CompareMost for each available airline. 
  • Try to avoid flying on Fridays and Sundays. Tickets on those days usually command higher prices, because the majority of people want to visit Vegas. 
  • Travelers often find competitive fares when booking several weeks in advance, it's always recommended to book your flight tickets 3-5 weeks ahead.
  • If you're on a tight budget, make sure that you have an fare alert set, because ticket prices could go up or down dramatically throughout the year

Seasonal Pricing

There is a large number of visitors flying from DEN to LAS throughout the year, but many travel patterns can be expected to affect the ticket prices on these flights.

January: Affordable Post-Holiday Travel

January typically has fewer visitors and is one of the cheapest months to visit. Travel pricing usually comes down after the first 2-3 weeks of the year.

February-April: Convention Season Begins

At the beginning of the year, Las Vegas hosts several large trade shows and conventions. Booking tickets for those particular days and around those events will typically be pricier as those visiting for business are willing to pay more.

May-August: Summer Vacation Demand

Summertime brings many people to Las Vegas on vacation, so demand rises. Similar to weekends, fares in summer tend to be much more expensive at the end of the week.

September-October: Lower Demand Window

This period marks the start of the colder seasons as summer vacationers head back home, resulting in lower prices overall. The second half of this period of the year will start to increase more when considering the holidays that are coming up!

November: Holiday Travel Begins

Starting at the beginning of November, many will start traveling again due to a large variety of holidays happening in December. Flights to and from Las Vegas at this point in time will see more people booking.

December: Highest Fares of the Year

Because New Year's Eve is in Las Vegas, prices will generally be the highest they are all year, around the holiday. If you are flying to the area for a specific reason, book early; it's usually recommended to book 6-8 weeks in advance!
