Singapore Airlines plans blockchain tech for frequent flyer spending

Singapore Airlines plans to use blockchain technology to give its frequent flyers a new way to spend their accumulated miles, it said on Monday. The company said a digital wallet app for its KrisFlyer loyalty programme would be launched in about six months and it would be signing up retail partners in the Singapore market to begin with. "I think we are the first airline to do it," Chief Executive Goh Choon Phong told the Singapore Airshow Aviation Leadership Summit, a gathering of aviation leaders on the eve of Asia's largest air show.
