The Vancouver Sun reports in its Tuesday edition Air Canada says capacity on its domestic services will increase more this year than previously forecast and that the airline's cost containment efforts have done better than expected in the second quarter. A Canadian Press dispatch to The Sun says the revised guidance was issued early Monday ahead of a presentation to investors in Toronto. Air Canada now expects 2013 domestic capacity will grow by 1.5 per cent to 2.5 per cent over 2012 levels -- a full percentage point above the levels announced last month, when Air Canada issued its first quarter results. Air Canada said Monday the expected increase to domestic capacity this year will be possible due to schedule changes. The company also says it has been doing better than expected on cost-containment during the second quarter, which ends June 30. Air Canada's adjusted cost per available seat mile will decrease by between 0.5 per cent and 1.5 per cent compared with the second quarter of 2012, a full percentage point better than the previous estimate. It also projected that seating capacity in the second quarter will be between 2 and 3 per cent above the comparable period last year.
