Colorado Springs Airport (COS) is a compact, easy-to-navigate airport serving the Pikes Peak region. It sits about 12 miles southeast of downtown Colorado Springs, with an estimated drive time of about 20 minutes under normal conditions. The airfield has operated since 1927, while the current three-level, 12-gate terminal opened in 1994.
Quick Answer
Colorado Springs Airport (COS) is served by five commercial airlines: Allegiant Air, American Airlines, Delta Air Lines, Southwest Airlines, and United Airlines. Together, they offer nonstop service to major hubs and leisure destinations, although several routes operate only seasonally. Always confirm dates and availability with the airline before booking.
Key Takeaways
- The current COS airline roster includes Allegiant, American, Delta, Southwest, and United.
- The airport’s published route map shows 17 U.S. nonstop destinations, but some routes are seasonal or operate only on selected days.
- American, Delta, and United provide useful connections through large hubs, while Southwest has the widest published nonstop network from COS.
- COS currently lists no year-round international nonstop route; limited seasonal Cancun service has operated in the past.
- The airport offers free Wi-Fi, food and retail, family care rooms, charging, accessible facilities, parking, rental cars, taxis, ride-app pickups, and public bus service.
At a field elevation of about 6,187 feet, COS operates in a high-altitude environment that airlines account for when planning aircraft performance. For passengers, the more noticeable advantages are the airport’s short walking distances, single commercial terminal, and simpler layout compared with a major hub. According to the airport’s official quick facts, the farthest gate is less than 1,000 feet from the ticket counters or baggage carousels.
Colorado Springs Airport handled 2,448,001 total passengers in 2025, showing that a relatively compact terminal can still serve substantial regional demand.
Major Airlines Serving Colorado Springs
The official Colorado Springs Airport airline directory lists five passenger airlines. American Airlines, Delta Air Lines, Southwest Airlines, and United Airlines provide a mix of hub connections and point-to-point routes. Allegiant Air focuses mainly on leisure-oriented service.
American Airlines
American Airlines flies nonstop from COS to Dallas/Fort Worth International Airport (DFW) and Chicago O’Hare International Airport (ORD). Dallas/Fort Worth is especially useful for connections across the United States, Latin America, and other international markets.
Delta Air Lines
Delta serves Atlanta (ATL), Salt Lake City (SLC), and seasonal Minneapolis–St. Paul (MSP). These routes give travelers access to Delta’s larger domestic and international networks without first driving to Denver.
Southwest Airlines
Southwest has the largest published list of nonstop destinations from COS. Its route map includes Chicago Midway, Dallas Love Field, Denver, Houston Hobby, Las Vegas, Phoenix, San Diego, and seasonal San Antonio. Flight frequency and operating days vary by route.
United Airlines
United operates nonstop flights to Denver, Houston Intercontinental, and Chicago O’Hare. Denver usually offers the greatest number of connection choices, while Houston and Chicago can be useful for trips that would otherwise require an extra stop.
Regional Airlines and Low-Cost Carriers
COS does not currently list a separately marketed regional airline in its public passenger-airline roster. Some flights sold by American, Delta, or United may still be operated by regional partners or regional aircraft, so travelers should check the “operated by” line on the booking page.
Allegiant Air is the airport’s primary ultra-low-cost carrier. The published route map includes Phoenix/Mesa (AZA), Santa Ana/Orange County (SNA), and St. Pete/Clearwater (PIE). Allegiant routes often operate only a few days per week, and the lowest advertised fare may not include seat selection, a carry-on bag, or a checked bag.
Pro Tip: Compare the final trip cost, not only the base fare. Add baggage, seat, boarding, change, and airport-transport costs before deciding which airline is cheapest.
Destinations and Routes from Colorado Springs
The airport’s current nonstop route map shows the destinations below. This is a route overview, not a promise that every flight operates daily or throughout the year.
| Airline | Published nonstop destinations from COS | Route notes |
|---|---|---|
| Allegiant Air | Phoenix/Mesa (AZA), Santa Ana/Orange County (SNA), St. Pete/Clearwater (PIE) | AZA is seasonal; other schedules may pause or change. |
| American Airlines | Chicago O’Hare (ORD), Dallas/Fort Worth (DFW) | Both are major connecting hubs. |
| Delta Air Lines | Atlanta (ATL), Minneapolis–St. Paul (MSP), Salt Lake City (SLC) | MSP is seasonal. |
| Southwest Airlines | Chicago Midway (MDW), Dallas Love Field (DAL), Denver (DEN), Houston Hobby (HOU), Las Vegas (LAS), Phoenix (PHX), San Diego (SAN), San Antonio (SAT) | SAT is seasonal; operating days vary on other routes. |
| United Airlines | Chicago O’Hare (ORD), Denver (DEN), Houston Intercontinental (IAH) | All three provide broad connection options. |
Warning: Airline schedules can change with demand, weather, aircraft availability, and seasonal planning. Confirm the exact operating dates on the airline’s website before paying for hotels, rental cars, or other nonrefundable travel.
Seasonal Route Timing
The airport’s April 29, 2026 schedule update said Allegiant’s Phoenix/Mesa service was scheduled to return October 17, 2026; Orange County service was expected to pause from August 8 through October 1; Delta’s Minneapolis–St. Paul season was scheduled for June 7 through September 30; and Southwest’s San Antonio service was scheduled to return November 21. These dates can still change, so use them only as a planning reference.
Can You Fly Internationally from COS?
As of July 26, 2026, the airport’s current route map lists U.S. destinations only. Southwest previously operated limited seasonal nonstop flights to Cancun on selected dates, including dates through April 4, 2026. That means COS has handled international passenger service, but travelers should not assume a nonstop international flight is currently available without checking the latest schedule.
Note: International trips are still easy to arrange with one connection through hubs such as Dallas/Fort Worth, Denver, Houston, Atlanta, Chicago, or Salt Lake City.
Which Airline Is Best for Your Trip?
The best airline depends on destination, total price, schedule, loyalty benefits, and connection risk. The following comparison can help narrow the choice.
- Choose Allegiant when it offers the only convenient nonstop to a leisure destination and the final price remains competitive after optional fees.
- Choose American for connections through Dallas/Fort Worth or Chicago O’Hare.
- Choose Delta for access through Atlanta, Salt Lake City, or seasonal Minneapolis–St. Paul.
- Choose Southwest when its broader nonstop selection or point-to-point schedule best matches your trip.
- Choose United for frequent Denver connections or trips that work better through Houston Intercontinental or Chicago O’Hare.
When two itineraries are close in price, compare the complete travel time. A nonstop flight from COS may be worth more than a cheaper itinerary that requires driving to Denver, paying higher ground-transport or parking costs, and allowing extra time for a much larger airport.
Amenities and Services at Colorado Springs Airport
COS offers food, retail, connectivity, family facilities, and accessibility services in a compact terminal. Hours may change according to the flight schedule, so late-night travelers should not assume every concession will remain open.
Food and Retail
Current options listed on the airport’s food and retail page include Atrevida Beer Co., Peet’s Coffee, and The Atrium before security. Post-security choices include Pikes Perk, Mountain View Food Court, Colorado Craft, Hudson Nonstop, and Hudson Evolve.

Free Wi-Fi is available through the flyCOS network in the concourse, security checkpoint area, fireplace area, and sections of baggage claim. USB and AC charging ports are available around concourse seating, with additional mobile charging stations throughout the secure area.
Families, Accessibility, and Pets
The airport lists two family care rooms, a private lactation room, accessible parking and terminal facilities, wheelchair assistance, and a pet relief area. Passengers who need a wheelchair should request assistance from their airline when booking or before travel.

Parking and Ground Transportation
Colorado Springs Airport is located at 7770 Milton E. Proby Parkway, Colorado Springs, CO 80916. Short-term, long-term, overflow, and valet parking are available. The airport also provides a free cell phone waiting lot for drivers picking up arriving passengers.

| Long term | $1 per hour; $8 daily maximum | Free shuttle service operates during designated flight times. |
| Overflow | $8 per day | Opens when long-term lots are full; card payment only. |
| Valet | $19 per day; $22 for covered or EV-charger-capable valet | Counter is on the departure level near airline ticketing. |
These were the airport’s published rates when this article was updated; check the official COS parking page before travel because prices and lot availability can change.
Ground transportation includes taxis, hotel and private shuttles, ride-app services, rental cars, and Mountain Metro Transit Route 37. On-airport rental-car counters are in baggage claim. Taxi and shuttle services are independent companies rather than airport-operated services.
Tips for Flying Out of Colorado Springs
- Arrive at least 90 minutes before departure. COS’s official security guidance recommends this minimum. Allow more time during holidays, severe weather, or when checking bags.
- Check in online. The airport’s airline directory says its current carriers do not offer curbside check-in at COS, so online check-in can reduce time at the ticket counter.
- Confirm the airport code. Colorado Springs is COS. Do not confuse Phoenix Sky Harbor (PHX) with Phoenix/Mesa Gateway (AZA), or Houston Hobby (HOU) with Houston Intercontinental (IAH).
- Review baggage fees before booking. Policies differ by airline and fare type, especially on low-cost routes.
- Check seasonal dates twice. A route can appear on the airport map even when it is not operating during your specific week.
- Watch the weather and your airline app. Colorado weather can change quickly, and delays may begin at a connecting hub even when conditions at COS are clear.
- Plan parking before peak travel. Follow signs to overflow parking if the long-term lot is full, and allow time for the shuttle.
Future Expansion and Development Plans
Colorado Springs Airport completed a 20-year master plan in 2022 to guide long-term facility development. More recently, the airport has been finishing the multi-year ElevateCOS concourse modernization project. An official update published April 29, 2026 said the project had entered its final phase and was on track for completion on July 31, 2026.
Recent improvements have included renovated passenger areas, terrazzo flooring, updated concessions, an advanced exit-lane security system, common-use technology intended to improve gate flexibility, and a federal inspection station completed in 2025. These are confirmed projects and upgrades; they are more reliable than unsupported speculation about a major terminal expansion or new routes that have not been announced.
Conclusion and Recommendations for Travelers
Colorado Springs Airport offers a practical alternative to driving to Denver for many trips. Its five-airline roster provides nonstop access to major connecting hubs and several leisure destinations, while the compact terminal, affordable long-term parking, free Wi-Fi, and short walking distances can make the departure experience simpler.
The main limitation is schedule depth. Some Allegiant, Delta, and Southwest routes are seasonal or operate only on selected days. Before booking, compare the full cost and total travel time, confirm the exact flight dates with the airline, and review the airport’s current route map. For many travelers in southern Colorado, a convenient COS nonstop or one-stop itinerary can be the best overall choice even when the base fare is not the absolute lowest.
