Porter Airlines says the Federal Court of Appeal has denied an appeal by larger rival Air Canada related to the allotment of tarmac slots at Billy Bishop Toronto City Airport.
Air Canada had challenged how takeoff and landing slots were awarded at the island airport just south of Toronto's downtown core, saying they were unfairly handed out.
But the Federal Court ruled in July 2010 that the Toronto Port Authority acted fairly when it handed out 44 of 90 new slots to Porter.
Air Canada was allotted 30 slots and U.S.-based Continental Airlines got 16.
Porter says the court also ruled that Air Canada must pay the smaller regional airline's legal costs, as well as those of the port authority.
