These months tend to offer the best combination of good weather at your destination and lower airfare demand.

About Denver International

Denver International is United Airlines' second-largest hub after Chicago, which means consistent domestic capacity and surprisingly good international options for a mountain-west airport. It's the fifth-busiest airport in the US by passenger count, serving as the main gateway for Colorado's Front Range. The airport sits at 5,431 feet elevation — higher than most US airports — which occasionally affects flight operations in winter but rarely causes delays. DEN has undergone major expansion since 2025, with new gates opening for international routes. If you're based in Colorado or the Rocky Mountain region, DEN is your primary option; it's 23 miles northeast of downtown Denver and surrounded by high plains, making it windier than coastal airports but generally reliable year-round.

Terminals & Airlines

Denver has one unified terminal building (technically Terminal A/B/C in sections) with no separate terminals like major East Coast hubs. United dominates with 60+ daily flights and occupies the north gates (primarily gates A1-A50). Southwest operates from mid-terminal gates (B20-B65). All other carriers — American, Delta, Alaska, Frontier, Spirit, JetBlue, and international carriers — operate from south gates (C). TSA PreCheck and Clear lines are in the main security checkpoint; the north security checkpoint near United gates is usually faster during morning waves. International flights depart from gates C42-C90.

Getting to the Airport

RTD Airport Train (A-Line): $11.50 one-way from downtown Union Station, 37 minutes, runs every 15 minutes peak hours. This is the best option — direct, predictable, no traffic. Uber/Lyft: $35-55 from downtown during off-peak, $50-85 during 6-9 AM rush. Takes 25-35 minutes depending on traffic on I-270. Rent car agencies are at ground level with typical Denver prices ($45-70/day for economy). Parking at DEN: $18/day in surface lots (Pena Lot), $28/day in covered Garage 1-2. For trips under 5 days, Uber is cheaper than parking; beyond that, park at Garage 1 (closest, $28/day) or use covered Pena ($25/day, further walk).

Parking

Garage 1 is most convenient but fills first ($28/day). Economy lot parking ($18/day, Pena Boulevard) is a 10-minute walk but much cheaper for week-long trips. If you're departing early morning, pay for valet ($35-40) to save the walk and avoid the pre-5AM lot rush. DEN's lots are outdoor-heavy; winter snow removal is solid but icy conditions happen January-February. Don't leave valuables visible — the long-term lot has occasional break-ins. For frequent travelers, United Club membership includes discount parking.

Pro Tips for Flying from Denver

1

United dominates Denver with cheap connecting fares through this hub. If you're flying transatlantic or to Central America, check United's DEN connections — they're often $100-200 cheaper than booking direct from coastal cities.

2

The A-Line train has a two-hour window before departure; if you're cutting it close, take the 15-minute earlier train (it's packed but reliable). Uber during peak hours (6-9 AM, 3-6 PM) can add 10-15 minutes.

3

Frontier, based in Denver, has aggressive sales from DEN to Mexico and the Caribbean in off-season (May-June, September). Set a price alert for DEN-CUN, DEN-PVR, DEN-SJD routes in spring.

4

Winter storms (December-March) occasionally ground flights for 2-6 hours. Check snow forecasts, not just flight status, the night before. Tuesday-Wednesday departures in winter are most reliable; avoid Friday evening travel.
