HONG KONG (AFP) - Virgin Airlines is to offer frequent-flyer "Space Miles" that passengers can put towards flights in space with the company's soon-to-be-launched Virgin Galactic, boss Richard Branson revealed.

The British tycoon, in Hong Kong to promote new Virgin flights to the city, said customers who collected two million points would be entitled to be among the first commercial astronauts when his space plan takes off in two years.

"There are already 30 people in the world who have collected enough air miles to fly into space," Branson said Tuesday.
