Oil marketing companies have stopped refuelling Air India planes at six airports – Kochi, Pune, Patna, Ranchi, Vizag and Mohali – over non-payment of dues. That has forced aircraft flying to these cities to upload double the fuel quantity at the origin airport. That, Times of India says, increases the plane’s weight, likely resulting in passengers being offloaded on long routes. The cash-strapped airline, which owes oil companies about ₹3,000 crore, has sought an emergency funding of ₹2,500 crore from the government as debt.
