It has happened again. A passenger on an IndiGo flight, Aditya Narayan, son of Bollywood playback singer Udit Narayan, abused a woman staff member of IndiGo at the check-in counter and then abused the Duty Manager. It has been caught on cellphone video with Aditya Narayan clearly threatening the Duty Manager. In the end, IndiGo allowed him to fly between Raipur and Mumbai yesterday after he apparently apologised. On The Buck Stops Here, we look at the Indian air traveller. What gives anyone the right to be uncouth, rude, abusive and threatening to anyone on any airline? And are the government's new rules specific to its no-fly list strong enough?
