Jet Airways cancelled at least 14 flights to various destinations on Sunday after some of its pilots reported “sick” over non-payment of their dues. The jet employees are protesting against non-payment of salary, dues and the indifferent attitude of the National Aviator’s Guild in taking up the issue with the management. The fragility of this sector are at times beyond the airline company’s control. When the price of fuel goes up, Indian airlines make losses; when the rupee depreciates, Indian airlines make losses. And, of course, the aviation worldwide is famously crisis-prone. Over the past four years, passenger growth in India has been rapid and the number of flights taken has increased between 15 to 20% per year. And the demand this year is likely to be the highest in the world. Yet the industry itself hasn’t benefited. And not only Jet but almost every Indian airline is struggling with it.
