GoAir has joined IndiGo, Air India and SpiceJet in banning comedian Kunal Kamra from flying any of its flights till further notice, for roasting a TV anchor on a flight. Indigo has cited "unacceptable behaviour" as the reason for action, after Kamra posted a video online in which he can be seen heckling Republic TV editor Arnab Goswami on an IndiGo flight to Lucknow on Tuesday. IndiGo has put Kamra on a 'no-fly' list for six months. The comedian has said that he wanted to ask Goswami a few questions, which he pretended to ignore, so he made the video. Civil Aviation minister Hardeep Puri had advised other airlines as well to take action against Kunal Kamra.
