Wheels Up Experience today announced that it has closed the previously announced investment by Delta Air Lines, Certares Management LLC, Knighthead Capital Management LLC and Cox Enterprises.

The new investment structure combines the experience of Delta, the No. 1 premium airline, with the travel and tourism focus of Certares and turnaround and restructuring experience of Knighthead. It includes an agreement for a $500 million credit facility to Wheels Up, with funds contributed by Delta and CK Wheels LLC, which is co-managed by affiliates of Certares and Knighthead, and Cox. The announcement follows last week’s selection of George Mattson as the company’s new CEO.

“This investment represents both an important source of capital for Wheels Up to support our strategy for financial stability, future profitability and long-term growth on behalf of our members and customers, as well as a vote of confidence in our path forward from a group of investors with deep experience in the premium travel space,” Mattson said. “We look forward to working closely with Delta and our other investors to deliver best-in-class operating performance and an exceptional customer experience which, as we deepen our commercial partnership, will also enable us to provide a one-of-a-kind seamless connection between private and premium commercial travel.”
