Hong Kong: New budget airline Jetstar Hong Kong said Friday it has sold a total of six of its aircraft because it is taking longer than expected to get a licence to operate. The airline, which is a joint venture between Australia’s Qantas, China Eastern Airlines and Hong Kong-based Shun Tak Holdings applied for regulatory approval in 2012 in the southern Chinese city. An airline will only be given a operation licence if its principle place of business and centre of its decision-making is in Hong Kong, according to local laws.
