Aspen-Pitkin County Airport has one runway, Runway 15/33, oriented along the river valley, roughly northwest to southeast. The runway is named for the magnetic bearing of the centerline, rounded off to the nearest ten-degree interval, with the third digit dropped. For example, an airplane approaching Runway 15 for arrival has a final course bearing of 148 degrees relative to magnetic north. In 2007 Runway 15/33 was rehabilitated removing the porous friction course (PFC) surface replacing it with grooved asphalt, and installed a runway weather information system (RWIS). The runway is 8,006 feet long by 100 feet wide. The pavement is rated at 80,000 pounds for single wheel (landing) gear aircraft and 100,000 pounds for dual wheel gear aircraft. Aircraft that have a wing span of 96 feet or more are restricted from the using the airport per County Ordinance. Wind coverage, or the amount of time that crosswind components are within acceptable levels, is 97.6 percent at 12 miles per hour and 99 percent at 15 miles per hour. According to Air Traffic Control Tower personnel, 99 percent of all departures are to the north, while 85 to 90 percent of arrivals are to the south.
A partial parallel taxiway, whose centerline is 221 feet from the runway centerline, measures 6,400 feet long by 50 feet wide and is paved with asphalt. The taxiway parallels the runway from the south end to Taxiway "A-1"
Runway 15/33 is equipped with a Medium Intensity Runway Lighting (MIRL) system. In addition, there is Runway End Identifier Lights (REIL) at the approach end of Runway 33. A Medium Intensity Approach Lighting System with Sequenced Flashers (MALSF) and a Precision Approach Path Indicator (PAPI) system are at the approach end to Runway 15. The edge of Taxiway A is marked with edge reflectors to provide guidance to pilots during nighttime operations. There is also a rotating beacon to assist pilots in locating the airport facility at night and during periods of inclement weather. There is no precision instrument approach to the airport. The local airport airspace is controlled by the FAA Air Traffic Control Tower and the airport is surrounded by Class D airspace. The Control Tower is operational daily from 7:00 am to 10:00 pm. The airport is closed to general aviation Stage II turbo jet operations between 30 minutes past official sunset and 11:00 pm. The airport is closed to all traffic between 11:00 pm to 7:00 am.
The airport is served by two airlines operating daily, year-round scheduled service. The airlines serving the airport are United and American Airlines. The airlines occupy ticket counters, baggage facilities and offices at the airport for full services to the flying public.
Passenger services inside the terminal building include: full service restaurant and bar; courtesy phones; rest room facilities; gift shop; public telephones; vending machines; newspaper racks; lockers; airport administration offices; various ground transportation providers; and five rental car agencies.
