A man used a loophole in an air-miles scheme to book £40,000 worth of flights around the world for under £200. Sam Huang used credit card schemes and the absence of routing rules in the flight booking system to secure the series of first-class flights with Emirates airline that included around-the-world stop-overs for just £196. Like many other people before him, Mr Huang took out lots of credit cards with air miles and began racking up points. Using seven of these cards, he collected his miles over a few months. However, calling himself the “infrequent flier”, he explained that he didn’t accumulate his miles by booking lots of flights. The majority of banks have limitations on how often rewards bonuses can be earned, but Mr Huang found a loophole to get him stop-overs on a flight from Singapore to New York.
