Grandstar Cargo International Airlines, the joint venture cargo carrier formed by Korean Air Cargo and Sinotrans is finally set to take to the skies after regulatory problems delayed their original plans to launch in middle of last year. The Tianjin- based cargo carrier will begin with a B747-400 freighter flying three times a week to Frankfurt. In addition to the B747, the airline is getting an A300-600 freighter, which KAL converted from passenger configuration a year ago. The aircraft is earmarked for regional sectors, possibly including Seoul, Tokyo, Shanghai and Singapore.
