MUMBAI/BENGALURU, Dec 6 - Crowds at Indian airports eased on Saturday but hundreds of passengers were still gathering outside Bengaluru and Mumbai airports as 385 IndiGo flights were cancelled, in the fifth day of a crisis that has hit the country's biggest airline.

Air travel across India has been in turmoil this week after IndiGo cancelled thousands of flights, prompting the government to announce special relief for the carrier and operate some trains to help clear the backlog.
