JETRIDE ACHIEVES HIGHEST INDUSTRY QUALITY RATING

Operations in St. Louis Established.

COLUMBUS, Ohio — JetRide, a wholly-owned subsidiary of AirNet Systems Inc. (NYSE:ANS) and a premium provider of on-demand passenger charter services, has joined an exclusive group of aviation operators by receiving the Platinum rating for quality from the Aviation Research Group/US (ARG/US).

Information and safety ratings on 847 registered Part 135 jet carriers are available thru the ARG/US system, and only 29 have achieved Platinum status. Furthermore, only 270 operators have achieved the ARG/US Gold status.

“JetRide has now been formally recognized as being among the elite in passenger charter services and operational quality,” said Joe Biggerstaff, AirNet’s chairman of the board, chief executive officer and president.

In conjunction with the ARG/US audit, JetRide has added another base in St. Louis for its expanding passenger charter fleet of 10 Lear 60 jets and four Lear 35 jets. JetRide’s other bases of operation include Los Angeles, Scottsdale, Ariz., Dallas, Birmingham, Ala., Chicago, Columbus, Ohio, Lancaster, Pa. and Bedford, Mass.

“The ARG/US Platinum rating adds value for our customers, reassuring them that we engage in quality programs and business practices that ensure good service and provide enhanced safety,” said Robert Austin, JetRide’s vice president.
