Membership fleet access program Wheels Up now has 750 members and is on track to have 1,000 to 1,200 members and 37 aircraft by year-end, CEO Kenny Dichter announced this week at NBAA 2014. The fleet, operated by Gama Aviation, currently consists of King Air 350i turboprops and pre-owned Citation Excels/XLSs–with 27 and 10 of these aircraft, respectively, in the fleet by January–as well as Bombardier Global 5000s owned by Switzerland-based VistaJet and operated by Jet Aviation Flight Services.

Concurrent with its membership and fleet growth, Wheels Up has been expanding its geographic reach, establishing bases in Houston and Dallas. Dichter said the company is now “making a big push out west” into the California market, where it has five King Airs and two Excels/XLSs.

Wheels Up co-founder and president David Baxt said Chicago would likely be the next base for the company’s national expansion, followed by the Pacific Northwest, with expansion into Western Europe with its King Air 350is by the middle of 2015.
