KATHMANDU, March 7: The airline operators of Nepal have decided to proportionately ground their aircraft as the demand of air service is likely to decline due to the impact of the global coronavirus crisis. Yog Raj Kandel, spokesperson at the Airlines Operators Association of Nepal (AOAN) said that, the decision comes in the wake of the need to minimize the flying cost of aircraft. “Our proposition is to use aircraft as per the requirement to control the operating cost,” he said, “This time of the year is already an off-season for tourists and with the fear of coronavirus, aviation industry has been hit hard.”
