The Wyvern Wingman standard, which has recognised Sterling Aviation once more, provides a safety benchmark that allows air charter customers to assess performance expectations against best practices.

Wheels Up has acquired aircraft management and charter company Gama Aviation Signature, the exclusive operator of its fleet of King Air 350i, Citation Excel/XLS and Citation X aircraft.

Newcomers to Gama Aviation Signature's charter fleet feature amenities such as wi-fi and Airshow, and are outfitted with seating for eight to 15 passengers. It now offers more than 200 aircraft in the United States.
