National events — e.g., Coachella (April, near LAX), New York Fashion Week (September), and Austin’s SXSW (March) — also affect connecting-route pricing from Denver (DEN). When planning, search targeted phrases like "cheap flights to Denver during Great American Beer Festival" and book early to avoid price spikes.

The best time to fly from Denver International Airport (DEN) for cheapest economy fares is typically during shoulder seasons — January (post-holiday), late April to early May, and September. Midweek travel (Tuesday–Thursday) and late-night or early-morning departures often provide the best economy pricing. Avoid peak holiday windows (Thanksgiving, Christmas/New Year) and major local events unless booked well in advance. Use search queries like "best time to fly DEN cheap" and set multi-month calendars to pinpoint low fares.

Choosing between direct (nonstop) and connecting flights from Denver International Airport (DEN) depends on priorities: nonstop flights save time and reduce missed-connection risk but can cost more in economy fares; connecting flights often provide the cheapest economy options due to competition and routing flexibility. For travelers aiming to minimize price, search for one-stop itineraries or alternate hubs (ORD, DFW, LAX) that frequently offer discounted economy seats. Weigh total door-to-door time, baggage transfer risk, and potential savings when deciding.

Major carriers serving Denver International Airport (DEN) include United Airlines (hub), Southwest Airlines (high frequency), Frontier Airlines (ultra-low-cost), Delta Air Lines, and American Airlines. For cheapest economy fares, compare base fare differences plus ancillary fees (bags, seat selection). Frontier often has the lowest headline fares but higher add-on fees; Southwest includes two free checked bags and can be better overall value for families. Legacy carriers may offer better reliability and more flexible change policies — use search queries like "United vs Frontier DEN economy" to compare total costs.

Seasonal travel around Denver (DEN) changes significantly: winter demands rise for ski areas (December–February), spring and fall shoulder seasons (April–May, September–October) offer cheaper economy fares, and summer (June–August) is high for family travel. For cheapest economy fares, travel in shoulder seasons, fly midweek, and remain flexible on times and airports. Pack appropriately for season-specific weather (layers in spring/fall, heavy-snow gear in winter) and pre-book ground transportation to ski resorts or mountain towns.
