Find Cheap Flights from Dallas (DFW) to Denver (DEN): Your Mile-High Guide

1. When arriving at DEN, remember that the airport is located about 25 miles from downtown, so factor in at least 45 minutes for the A-Line commuter rail or a rideshare to reach your hotel. 2. To avoid the worst of the Texas heat and the Colorado snow delays, aim for mid-morning flights which typically offer the best balance of on-time reliability and comfortable boarding temperatures. 3. Drink plenty of water before and during your flight to help your body acclimate to Denver’s high altitude, which can cause dehydration or mild headaches for those arriving from sea-level elevations like Dallas. 4. If you aren't checking bags, DFW’s Skylink train makes navigating between terminals incredibly fast, so don't worry if your gate changes at the last minute.

Airfare for the DFW to DEN route tends to peak during the winter months, specifically between December and March, as Dallas residents flock to Colorado for premier skiing and snowboarding conditions. Conversely, you can often find the most competitive rates during the late spring and early autumn shoulder seasons. Mid-week departures, particularly on Tuesdays and Wednesdays, generally offer significant savings compared to the high-demand Friday and Sunday evening time slots.
