Atlanta-based Delta Air Lines is concerned that Canada’s plans to bill foreign airlines for the right to use its airspace may translate into higher fares, according to an airline spokesman.  The US charges no such fees.

“Anything that places an additional financial burden on a carrier is not good for the customer,” said Todd Clay, whose company has offered non-stop flights from Atlanta to Toronto and Montreal since March.

A US-Canada pact opened new routes this spring, but ValuJet Airlines announced June 28 that it will drop its service from Washington DC to Montreal because the flights are losing money.  Air Canada, however, will offer daily nonstop flights from Atlanta to Montreal starting Wednesday, July 5.

Canada reportedly will start the new policy November 1, leading to the privatization of the Canadian air traffic control service. Airlines have until the end of July to raise objections to the proposal.
