Wheels Up, a major private aviation supplier, has acquired Mountain Aviation, an operator of charter flights with bases in Denver; Teterboro, New Jersey; and Southern California. The acquisition, according to an announcement, accelerates Wheels Up's platform to better serve increasing flight demand from its rapidly growing membership and charter marketplace.  Mountain Aviation's wholesale charter operations and Super Mid fleet, said the announcement, are a perfect complement to Wheels Up's previous acquisition of Travel Management Company, which operates the industry's largest wholesale floating fleet of light jets.  With the acquisition, Wheels Up will add 59 planes, most of which are Citation X aircraft, to its fleet. It also plans to further expand the Citation X fleet in 2021 to enable a consistent experience for Wheels Up members and customers and drive efficiencies in aircraft maintenance. Kenny Dichter, founder of Wheels Up, said the deal “further strengthens the Wheels Up suite of products and services that we offer to our members and customers and enhances our unique total aviation solution positioning."
