From booking to airport arrival, find tips to help you plan your flight with more confidence.
  • For the best chance at a low fare to Denver, aim to book around 5 weeks before you fly. That window historically saves about 31% versus last-minute pricing based on KAYAK booking data over the last 12 months.
  • For flights to Denver, recent KAYAK data shows that stronger deals tend to land around $199 round-trip. If you see a fare below that threshold, it's a strong deal – book before the price climbs back up.
  • If you can choose when to go, time your trip to Denver around January. Round-trip fares historically average $246 that month – typically the cheapest month to travel based on the last 12 months.
  • Before you book:

    • Check the route's typical price range so you can spot a deal.
    • Confirm baggage fees and seat-selection costs on budget carriers.
    • Verify whether you need any travel documents beyond ID.
    • Pick a departure airport, since your nearest may not be the cheapest origin.
  • Shift your departure to evening to save up to $49 per round-trip. Evening flights to Denver average $283 compared to $332 for morning flights. See the time-of-day chart above for the full breakdown.
  • Bag allowances vary by airline, fare type, cabin class and route. On flights to Denver, some airlines may include bags at no extra cost. For example, United Airlines includes a cabin bag and a checked bag in Economy Class, Frontier includes a cabin bag and a checked bag in Economy Class and Southwest includes a cabin bag and a checked bag in Economy Class.
