http://www.bloomberg.com/news/2012-...for-jets-as-return-to-profit-is-forecast.html Air Canada is considering purchases of mid-sized jets amid growing confidence the country’s biggest carrier will be profitable next year after an anticipated fifth straight loss. Talks are under way with Boeing Co., Airbus SAS and Bombardier (BBD/B) Inc. for more than 100 aircraft, Chief Commercial Officer Ben Smith said in a telephone interview. A decision to buy planes may come “in the short term,” Smith said last week, sooner than the one-year timeline the airline gave on Nov. 8. Adding single-aisle models with the latest fuel-saving technology that can carry about 150 passengers could help Air Canada shed its status as North America’s least-efficient carrier. Its fleet is twice as old as that of discounter WestJet Airlines Ltd. (WJA), which Montreal-based Air Canada is challenging by creating a low-cost unit.
