The four airlines that banned stand-up comedian Kunal Kamra for alleged 'unruly behaviour' during a Mumbai-Lucknow flight invited severe brickbats on Wednesday. While DGCA chief Arun Kumar told mid-day the airlines were right, experts said Kamra has a good chance of winning if he were to sue.

On Wednesday, IndiGo, GoAir, SpiceJet and Air India banned Kamra from flying for six months, while Vistara said, "Vistara stands firm with its zero-tolerance policy against any behaviour or act that compromises the safety, security and dignity of its customers and staff. We will review and follow due process in such cases."
