Air Deccan has stopped its flights on the Pune-Nashik route owing to non-availability of slots at Pune airport, an airline source said. The flight was launched in December last year under the government's regional air connectivity scheme UDAN (Ude Desh ka Aam Nagrik). "The defence ministry had given us landing rights at Pune airport only for three months, which expired in February, following which our services on the Pune-Nashik route have been suspended for nearly two months," an airline source told PTI here.
