Airline Flights to Denver: Prices, Picks & Smart Savings

Denver International Airport (DEN) buzzes with activity daily, handling over 100 carriers. Planning a trip? Here's what you need to know about pricing, airlines, and avoiding headaches.

Denver Flight Prices: What to Expect

• Roundtrip deals from New York (JFK) start around $110 if booked 60 days ahead—last-minute bookings jump to $350 or higher.
• United commands 45% of DEN departures, with Delta at 20% and American at 15%. A Chicago (ORD) to DEN trip averages $135 one-way off-season.
• Southwest sometimes drops tickets to $99 on Tuesdays—but you gotta hunt for them early. Miss that window, and prices spike.

Top Airlines for Denver Routes

United’s your best bet for smooth travel from DEN. Their hub runs 25+ daily flights to big cities like Los Angeles (LAX) and Atlanta (ATL). Domestic seats offer 32 inches of legroom—Delta’s only 30 inches. Plus, their app updates gates instantly during Denver’s frequent weather delays.

Frontier? Skip it for short trips. I paid $120 extra for a 10kg carry-on on a DEN-DFW flight last month—a $35 fee just for a laptop bag. United lets you check a bag for free. Your sanity’s worth it.

When to Fly for Cheapest Deals

September’s the sweet spot for budget flights. Book a roundtrip from Boston (BOS) then? Pay $140 vs. $220 in July. Why? Airlines slash prices after summer crowds fade. I’ve booked client trips for $80 less per person by flying early September.

Avoid Fridays and Sundays—they cost 30% more. Fly Tuesday or Wednesday instead. A PHL to DEN flight I booked on a Tuesday cost $155, but the Friday price? $215. That’s $60 straight to your pocket.

Alternative Airports Near Denver

DEN’s the main hub, but Eppley Airfield (OMA) in Omaha offers cheaper tickets. A one-way OMA to DEN flight costs $65—but you’ll drive 3 hours or pay $70 for a shuttle. Only worth it if you’re flying Southwest (they serve OMA) and have a rental car ready.

International travelers might eye Colorado Springs (COS), 65 miles south. It’s not a full airport—just 5 weekly flights to DEN. The flight? $110. But you’ll wait 45 minutes for a shuttle. Only useful if you’re already at a COS conference.

Fastest Routes from Denver

Denver to Los Angeles (LAX) takes 2h 15m nonstop on United or American. Book Tuesday mornings? You might snag $125 roundtrip. Avoid Wednesday afternoons—business travelers push prices to $250.

For Chicago (ORD), United flies 14 daily nonstops (2h 10m, $130 off-season). Delta’s version adds 10 minutes. Connecting flights? They add 2+ hours and cost $40 more. Stick to direct—your clients won’t thank you for wasting time.

FAQs: Denver Flight Hacks

Q: Can I find a Denver flight under $100 roundtrip?
A: Sure—but only in January or February with Frontier/Spirit. I found a $98 AUS-DEN roundtrip in January 2024. But book 90 days ahead, and accept zero baggage. For reliable trips, $110’s the realistic low.

Q: Do any airlines offer free checked bags on DEN routes?
A: Only Southwest (two free bags on 15 routes) and JetBlue (one free bag on DEN-BOS). All others charge—like United’s $35 fee for a 10kg bag on short hops. Southwest’s the only real winner here.
