Airport Breakdown

DEN

Denver International Airport

Best for

International flights, Caribbean/Central America routes, and anyone flying anywhere except Mexico. DEN has 6x the airline competition and nonstop options COS can't touch. Use this if you're going to Europe, Asia, or anywhere beyond North America.

Not ideal for

Flying to Cabo, Puerto Vallarta, or Cancun (COS often undercuts by $50-150). Also skip DEN if you live south of Colorado Springs—the drive kills any savings.

Cheapest for: Western Europe (London/Paris often $400-550 cheaper than COS), Tokyo, Australia, and Central America when flying off-peak. Economy pricing 15-25% lower than COS for most long-haul due to competition.

Getting There

RTD light rail from downtown Denver: $11 round-trip, 37 minutes to terminal. Uber/Lyft: $18-28 depending on surge, 25-40 minutes. Parking: $3.50/hour, $21/day uncovered or $29/day covered. From north Denver metro, light rail beats driving.

Pro Tip

Watch DEN prices on Tuesday mornings—United and Southwest drop competing fares here, and DEN's liquidity creates flash sales other airports never see. Set price alerts for Tuesday-Wednesday releases.

COS

Colorado Springs Airport

Best for

Mexico-bound trips (Cabo, Cancun, Puerto Vallarta, Los Cabos). COS has direct Southwest flights with $80-150 lower fares than DEN. Also ideal if you live in Colorado Springs, Pueblo, or the military communities—saves the 90-minute drive.

Not ideal for

Europe, Asia, or Caribbean (except specific Mexico routes). You'll connect through Denver or Dallas anyway. No nonstops internationally except Mexico. International inventory is thin and overpriced.

Cheapest for: Mexico all-inclusive packages (resort bundles cheaper here by $200-400 total), domestic Southwest routes (Dallas, Houston, Las Vegas, Phoenix are strong).

Getting There

Free parking (10-minute walk or shuttles from lot). Uber/Lyft: $12-18 to terminal, 8 minutes. Only 20 minutes from downtown Colorado Springs; 90 minutes from Denver metro. No public transit option—you drive or rideshare.

Pro Tip

COS Southwest flights to Mexico include 2 free checked bags; compare total cost vs DEN even if base fare looks higher. For Cabo/Puerto Vallarta, COS often wins by $300+ per person after baggage fees.

Our Verdict

Fly DEN for international travel outside Mexico, Europe, and long-haul (it's 20-25% cheaper with nonstops). Use COS exclusively for Mexico trips and if you live south of Castle Rock—Southwest's baggage policy and direct flights often beat DEN's total cost. If you're in Denver metro and going anywhere else, DEN is non-negotiable.

Frequently Asked Questions

Which Colorado airport is cheapest overall?

DEN for 85% of trips (Europe, Asia, Caribbean, domestic). COS only wins for Mexico—Southwest's Mexico routes and 2 free bags often save $250-400 per round trip to Cancun/Cabo compared to DEN carriers.

Which has more international flights?

DEN by a massive margin: 40+ nonstop international destinations vs COS's 6-8. DEN is a United hub; COS is a Southwest leisure airport.

How much time do I save flying from COS instead of DEN?

If you live in Denver metro, none—the 90-minute drive south erases any time savings. If you're in Colorado Springs/Pueblo, you save 2-3 hours total. The math only works south of Castle Rock.

Do I need a car rental after landing at either airport?

DEN: No—light rail and rideshare cover 80% of travelers. COS: Yes, almost always. COS has no rail, limited rideshare, and you're stuck without a car unless your hotel has a shuttle.

Which airport has cheaper parking?

COS: Free (10-minute walk). DEN: $21/day uncovered, $29/day covered. But if you're driving 90 minutes to COS, gas kills the parking savings.
