The Globe and Mail reports in its Friday edition that an executive at the International Air Transport Association, which represents 370 global airlines, has some advice for Prime Minister Mark Carney as he privatizes Canada's biggest airports: Don't do it. The Globe's Eric Atkins quotes IATA's Nick Careen saying the plan unveiled this week to transform airports in Montreal, Toronto, Calgary and Vancouver into for-profit companies would drive up fees paid by the airlines, which would be forced to pass on the higher costs to travellers. "We're against what they're doing because it is primarily done to extract cash," said Mr. Careen, whose members include Air Canada, WestJet and most other major carriers in the world. "We've got lots of examples of how that's failed." Examples around the world show fees paid by airlines and passengers go up when investment funds seeking returns of 8 or 12 per cent become owners of airports, he said. "Everybody wants a return on their investment. They're not doing this for free," Mr. Careen told The Globe. Air Canada said in a statement that it wants to ensure "that costs for passengers remain the same or lower, and reinvesting in aviation infrastructure, which is in dire need of it."
