The Globe and Mail reports in its Thursday edition that Air Canada's share price hit a one-year low Wednesday as the airline navigates higher fuel costs, competition and interest rates. A Reuters dispatch to The Globe notes that the airline slipped 62 cents to close at $17.13, marking its lowest price since Oct. 12, 2022, and a one-third drop from its recent peak in July. Shares of major U.S. airlines also fell Wednesday, after a disappointing fourth-quarter forecast from United Airlines a day earlier spooked investors and raised concerns rising costs are denting profits for carriers. United's shares were down as much as 8 per cent, hitting their lowest in a year, dragging peers Delta Air Lines, American and Southwest down 4 per cent each. On Tuesday, United forecast adjusted profit for the current quarter in the range of $1.50 (U.S.) to $1.80 (U.S.) per share, well below analysts' average expectations of $2.06 (U.S.), taking a hit from costs associated with higher jet fuel prices and expensive labour contracts. Profits at U.S. carriers have come under pressure as jet fuel prices jumped during the July to September quarter on tighter crude oil supplies. The Israel-Hamas conflict is also weighing on airline stocks.
