Passengers arriving on the first flight of the "seventh freedom of air" route from Prague, Czech Republic, disembark in Sanya, Hainan province, on Monday. Seventh-freedom rights allow foreign airlines to operate routes between two countries without flying to their home country. Operated by Kazakhstan's SCAT Airlines, the Prague-Sanya route is the first passenger flight under the seventh freedom of air in Hainan Free Trade Port. The new direct air connection enhances travel convenience and symbolizes a milestone for the free trade port.
