Best Time to Book Denver Flights

Denver flights drop 22% in price when booked 55 days before departure, per 360businesstour.com’s analysis of 12,000 bookings. January sees the lowest rates at $179 average (compared to $292 in July), but avoid the first week of January due to ski season demand. Booking on Tuesdays yields 8% cheaper fares than weekends, based on January 2025 data.

Hidden Fees to Avoid on Denver Flights

Frontier Airlines (ZV) charges $35 for a 10kg checked bag on DEN routes—not included in the $129 base fare. I discovered this when booking a March 2025 trip to Orlando (MCO) via DEN; my $129 ticket became $164 at checkout. Always verify baggage fees on the airline’s site, not third-party aggregators. Delta’s premium economy adds $58 for extra legroom, which competitors don’t require for similar comfort.

For alternatives, Dallas-Fort Worth (DFW) offers 17% cheaper flights to Europe but adds 90 minutes to travel time.
