The Globe and Mail reports in its Saturday edition that Air Canada is suspending flights to New York's John F. Kennedy airport as surging jet fuel costs prompt the airline to pare back its travel offerings. The Globe's Nicolas Van Praet writes that the airline will stop its four daily flights from Montreal and Toronto to JFK starting June 1 and plans to restart them Oct. 25. Customers affected will be offered other travel options. "Jet fuel prices have doubled since the start of the Iran conflict and some lower-profitability routes and flights are no longer economic," Air Canada said. JFK is the biggest serving the New York metropolitan area but it's not as key a hub for Air Canada as Newark Liberty International or LaGuardia. The airline said it will maintain its 34 daily flights from six cities in Canada to those two other New York airports. Airlines around the world have cut back their flight schedules, raised seat fares and taken other steps in response to war in the Middle East. Canada is largely self-sufficient in jet fuel, producing 80 per cent of its needs and importing much of the rest from refineries in the northeast United States, but Canadian airlines could see their routes affected by shortages overseas.
