Questions raised as India plans to take action against IndiGo over flight cancellations

Thousands of passengers have been left stranded over the past week, after India's largest domestic carrier IndiGo failed to make adequate preparations for new rules governing pilots' flying hours. Pilot unions and the public have raised questions over how the issue has been handled. The civil aviation watchdog, which has taken steps to cap airfares, has asked IndiGo to explain why it shouldn't face regulatory action. Meanwhile, opposition leaders have raised concerns about a lack of fair competition, with IndiGo dominating a 65% share of the growing domestic market. Rebecca Bundhun reports from Mumbai.
