✈️ Flight Guide: Fort Lauderdale (FLL) → Denver (DEN)

December offers festive events at both ends of the FLL–DEN route. Fort Lauderdale hosts holiday markets, the annual Winterfest Boat Parade and Las Olas holiday celebrations, while Denver features the Parade of Lights, Christkindl Market at Civic Center Park and ski-resort opening festivals in Vail and Breckenridge. These events can increase flight and hotel demand—book early and consider flexible dates to save on airfare.

The best time to fly FLL to DEN in December is midweek (Tuesday–Thursday) and outside major holiday peak windows (the week of Christmas and New Year's Eve). Early morning flights often have fewer weather-related delays in winter, and midweek departures tend to offer lower fares. For ski-season travelers, plan flights early in the week to get ahead of weekend crowds at mountain resorts.

Nonstop flights from Fort Lauderdale–Hollywood International Airport (FLL) to Denver International Airport (DEN) save time and reduce the risk of missed connections, especially important in winter when snow can affect schedules. Connecting flights may offer lower fares or more schedule flexibility but increase total travel time and the chance of weather-related disruption. If you have tight ski-resort transfers or carry sports equipment, nonstop service is often worth the premium.

Key carriers on the FLL–DEN route in December commonly include Frontier (budget carrier with many nonstop options), Southwest (bag-friendly fares with two free checked bags on some fares), and United/other legacy carriers with connecting options. Budget airlines often provide the lowest base fares but add fees for seat selection and checked skis; legacy carriers may include more flexible rebooking and broader connectivity across hubs.

Prepare for a warm departure from Fort Lauderdale–Hollywood International Airport (FLL) and winter conditions on arrival at Denver International Airport (DEN). Pack strategically: keep winter layers and boots in your carry-on if possible, confirm airline rules for skis and snowboards, and bring traction aids or insulated footwear for walking in snow. Allow generous connection times, carry a printed or downloaded itinerary and check airline rebooking policies in case of weather disruptions.

Nonstop flights between Fort Lauderdale–Hollywood International Airport (FLL) and Denver International Airport (DEN) generally take about 3 hours 45 minutes to 4 hours. Schedules in December frequently include early morning departures and late-afternoon flights to optimize connections with other hubs. Connecting itineraries commonly add 1.5–4 hours depending on layover city (Atlanta, Charlotte, Dallas/Fort Worth or Houston), so total travel time can range from 5.5 to 8+ hours.

To find cheap flights from Fort Lauderdale–Hollywood International Airport (FLL) to Denver International Airport (DEN) in December, search flexible dates (±3 days) and compare nonstop vs connecting itineraries. Book 30–60 days ahead for holiday travel, and watch for flash sales from low-cost carriers like Frontier or Southwest.

Bundle with airport parking or rental car discounts to further reduce total trip cost.
