NEW DELHI: For the past two months, Joel Fernandes had been counting days to a leave on Scottish holiday this summer. They had bought Mumbai-London-Mumbai tickets on Jet Airways and were supposed to leave on Monday. But now with the flight cancelled, Fernandes is wondering what to do as he had paid for the stay, internal travel and made other bookings in UK. “Jet is not responding. If nothing works out, may have to cancel this ticket and buy a new one at exorbitant spot fare,” Fernandes (name changed on request) said.This couple is not alone. There are thousands of people supposed to fly on Jet’s international tickets. While the airline has so far said it is not operating international flights till Monday, a question mark hangs on its survival. Jet’s three slots at London Heathrow have been returned to estranged partner Etihad. With UK hosting the ICC world cup this summer and expecting a surge in travel from cricket-crazed India, the cancellation of UK flights could not have come at a worse time.“Air France and KLM are trying to accommodate Jet’s passengers of its own cancelled flights to Amsterdam and Paris. Etihad may or may not accept our passengers. While some clarity in the airline’s future may emerge on Monday, passengers like Fernandes couple who are leaving early next week may consider cancelling Jet tickets, seeking a refund and buy new tickets on other airlines,” said a Jet official.The crisis has led to a rise in international fares on some sectors. Asked about the impact, travel portal Yatra ’s COO Sharat Dhall said: “Fares to Europe and North America are about 10-15% higher than they were last summer, however, other key India outbound sectors are not seeing a significant increase, with fares to Asia and the Middle East being almost flat as compared to last year. Fares to the UK have started rising and are already over 36% higher for travel to the UK on June 1 (which is close to the start of the Cricket World cup) than they were at the same time last year.”John Nair, travel major Cox & Kings’ head of business travel, said international “airfares would rise by at least 15% (as some capacity has been reduced). Other carriers, namely Gulf and others like Turkish have enough capacity to cater to the growing demand of Indian travellers as they have a deep network across Europe and the USA.In Far East, Indian carriers and LCCs (have) increased capacity and destinations such as Thailand, Malaysia and Singapore have enough capacity to take care of the present situation. Though we feel there could be price rise on specific dates, especially the peak periods of May and June, from North India.” India-UK fares could rise by 15% and closer to the date of the ICC world cup, he added.Jet partner Delta said in a statement: "Delta is aware of Jet Airways’ financial situation and its inability to operate its normal schedule. Delta is assisting Delta customers booked on Jet Airways flights to support their reaccommodation via alternative travel options. We apologize for any inconvenience caused to Delta customers impacted by Jet Airways.”
