ASPEN – Pitkin County could receive at least $3 million in annual rent from a proposed new private jet center—a sum that is 16 times more than what the current fixed-base operator pays at Sardy Field. Airport finance consultants explained the situation to the Pitkin County commissioners during a mid-August meeting on the airport master plan, which the county is expected to adopt this fall. The current draft airport plan includes building a new fixed-base operations facility—a terminal and services for private planes (or general aviation, as it’s officially called)—on the west side of the airport. The current fixed-base operator, Atlantic Aviation, leases a facility on the east side, and is expected to pay the county $167,000 in rent this year. The current lease was signed back in 1993 by Atlantic’s predecessor, and at that time was probably a fair deal for the county, airport director Jim Elwood told the commissioners.
