San Luis Valley Regional Airport/Bergman Field

San Luis Valley Regional Airport/Bergman Field (KALS) is a medium airport in Alamosa, CO. Pilots and dispatchers reference it by ICAO code KALS or IATA code ALS. It sits in North America.

San Luis Valley Regional Airport/Bergman Field is a regional commercial airport that doubles as a busy private-aviation base. Operators benefit from full instrument approaches and an FBO infrastructure scaled for regular jet traffic, often without the congestion of the nearest major hub.

The longest runway measures 8,521 ft (2,597 m), a heavy-class field. Representative aircraft that operate comfortably here include the Gulfstream G550, Falcon 7X, and Bombardier Global 5500. In practice this most heavy and super-midsize jets operate here without restriction.

San Luis Valley Regional Airport/Bergman Field sits at 7,539 ft above sea level. At this elevation, density-altitude effects are significant year-round. Operators should plan for reduced engine performance and longer takeoff rolls on warm days, and many flight departments require runway-analysis software for departures.

Local operations run on America/Denver. Scheduled airline service is light enough that it rarely interferes with charter movements, though planners should still expect to coordinate with the handling agent for international turnarounds.

SkyAccess inventory for KALS updates continuously as operators publish new empty legs and one-way repositioning trips. Pricing on each leg is available with a free account, and an inventory alert will email you the moment a leg appears on the route you care about.

Regional fields like KALS are a meaningful share of US private aviation — closer to the trip's actual origin or destination than the nearest major hub, with shorter ramp-to-cabin times that are the main reason owners and brokers prefer them.

San Luis Valley Regional Airport is two miles south of Alamosa, in Alamosa County, Colorado, United States. It sees one airline, subsidized by the Essential Air Service program. The airport reached 10,000 enplanements for the first time in its EAS participation with Boutique Air and is now classified as a non-hub primary airport.
