RE:Moody's Changes Air Canada's Outlook to Positive; Affirms B1Works for me! All I see in the grand scheme of things is the 5 year chart correlated with how well this company has done to improve it's business and balance sheet over the past 5 years while maintaining a reputation for being one of the best airlines in the business. Profits are always going to be volatile to the up and downside. Sustainability is key and from here on it's all about the balance sheet.
