Aspen Airport closes April 23 – May 21, 2026.

For 28 days starting April 23, 2026, KASE is offline entirely — not weather-affected, not slot-restricted, closed. Every Aspen-bound aircraft files an alternate at flight-plan time. For private aviation, that's KEGE 90% of the time, KRIL for smaller jets wanting Atlantic Aviation continuity, GJT for parties already routing in from the west, or DEN for the commercial-connection cohort.

The ground-transport problem is geography. KEGE handles its normal Vail/Beaver Creek volume plus the entire diverted Aspen demand. KRIL is a small Garfield County airport that on a normal day sees 46 aircraft; during peak closure days it has historically run far higher. Local rideshare is effectively unavailable. Taxi capacity is limited. The vehicles that move without friction are the ones that were already routing toward the right airport before the aircraft began its approach.

JetSet monitors aircraft tail numbers — not schedule data, not airline ETA feeds. Your block covers all four alternate airports under the same flat rate. If your charter operator changes the alternate at flight planning, the vehicle repositions automatically. No call to your desk. No rebooking. No renegotiation of price.

For executive assistants briefing principal travel during the closure window: hand off the tail number, the expected airport, the destination, and a contingency contact. That's all we need. The principal lands somewhere and is in the vehicle ten feet from the airstair, regardless of which airport "somewhere" turned out to be.
