Finding cheap flights from Denver doesn’t have to be complicated — with the right tools and timing, you can save hundreds on airfare. This guide walks you through the best tools and tricks to find cheap flights from Denver — whether you’re planning a weekend getaway or a big international trip.
1. Use Google Flights as Your Starting Point
Google Flights is the most reliable tool for comparing fares.
Search flexible dates instead of fixed ones — big savings appear midweek or shoulder season.
Pro Tip: Track prices on routes you care about and get email alerts.
2. Be Flexible with Dates & Destinations
Cheapest fares are often on Tuesdays, Wednesdays, and Saturdays.
Consider flying 1–2 days earlier or later than your original plan.
For destinations, check Google’s Explore Map to see the lowest fares from Denver across the globe.

3. Compare Denver’s Airlines Strategically
Frontier: Ultra-low fares, but watch for baggage/seat fees.
Southwest: 2 free checked bags, no change fees.
United: Nonstop international routes and a Denver hub.
Delta & American: Often pricier, but good for certain international deals.
4. Book at the Right Time
Domestic flights: book 2–3 months in advance.
International flights: book 4–6 months in advance.
Avoid booking at the last minute unless you’re flexible with dates.
