Airline Flights Denver — Updated Tips

How Much Do Flights to Denver Actually Cost?

Denver International Airport (DEN) handles over 100 airlines daily, cementing its status as a major travel hub. Score a roundtrip from New York (JFK) for just $110 if you book 60 days ahead—last-minute bookings can surge past $350. United controls 45% of DEN departures, followed by Delta (20%) and American (15%). A typical one-way Chicago (ORD) to DEN flight costs $135 outside peak seasons. Southwest occasionally drops tickets to $99 on Tuesdays, but you’ll need to search hard and book early.

Top Airline for Denver Travel

United’s DEN operations are unmatched for efficiency, with 25+ daily flights to major cities like Los Angeles (LAX) and Atlanta (ATL). Domestic routes offer 32 inches of legroom—more than Delta’s 30 inches—and their app updates gate changes instantly, a lifesaver during Denver’s frequent weather delays. Avoid Frontier for short trips: a recent 2-hour DEN to Dallas (DFW) flight cost $120 with a $35 fee for a 10kg carry-on (like a laptop bag). United includes free standard carry-ons with no hassle—your sanity’s worth more than $35.

Best Time to Book Flights to Denver

September delivers the lowest fares: expect $140 roundtrip from Boston (BOS) versus $220 in July. This dip happens when summer crowds fade and airlines cut prices to fill seats. I’ve booked client trips in early September and saved $80 per person. Skip weekends—Friday and Sunday flights cost 30% more due to vacationers. If you must travel Friday, book Tuesday or Wednesday: a Tuesday flight from Philadelphia (PHL) to DEN was $155 versus $215 on Friday—real savings for your Rockies adventure.

Alternative Airports Near Denver

Denver (DEN) is the primary airport, but Omaha’s Eppley Airfield (OMA) is a budget-friendly backup if you’re flying Southwest (they serve OMA). A one-way OMA to DEN flight costs $65, but factor in a 3-hour drive or $70 shuttle ride. Only worth it with Southwest and a rental car ready. For international arrivals, Colorado Springs (COS) is 65 miles south. It’s a minor hub with just 5 weekly flights to DEN. A COS to DEN trip costs $110 but requires a 45-minute shuttle wait—only practical if you’re already in COS for an event.

Fastest Routes from Denver to Major Cities

Nonstop flights from Denver to Los Angeles (LAX) take 2h 15m on United or American. The cheapest window? Tuesday mornings—$125 roundtrip is common. Avoid Wednesday afternoons when business travelers push prices to $250. For Chicago (ORD), United offers 14 daily nonstops (2h 10m, $130 off-peak). Delta flies the same route but adds 10 minutes. Connecting flights add over 2 hours and cost $40 more—skip them. Direct flights save time and money, which clients appreciate.

FAQs

Can I find a Denver flight under $100 roundtrip?

Yes, but only in January-February with budget carriers like Frontier or Spirit. I spotted a $98 roundtrip from Austin (AUS) in January 2024—but it required booking 90 days early with zero baggage included. For consistent value, $110 is the practical starting point.

Do any airlines cover checked bags on Denver routes?

Only Southwest (on 15 Denver routes) and JetBlue (select routes like DEN to Boston) include free checked bags. Southwest offers two free bags; JetBlue provides one. All other airlines charge fees—don’t assume otherwise.
