The Globe and Mail reports in its Wednesday edition that Air Canada notched the worst on-time performance among large airlines in North America in 2023, even as the carrier surged back to profitability. A Canadian Press dispatch to The Globe says that the country's biggest carrier landed 63 per cent of its flights on time last year, placing it last among the continent's 10 largest airlines. That means roughly 140,000 planes rolled up to the gate late -- more than 15 minutes after scheduled arrival. The score was five percentage points below the second- and third-lowest carriers, JetBlue Airways and Frontier Airlines, respectively. Canada's other major airline, WestJet, placed seventh in North America with a score of 69 per cent. Meanwhile, Delta Air Lines came first at 85 per cent, followed by Alaska Airlines at 82 per cent. Other, smaller airlines in Canada and the United States may have had worse on-time records than Air Canada's, but were not included in the report due to their size. Air Canada did not reply to Canadian Press's requests for comment. In the past, the Montreal-based company has pointed to a shortage of air traffic controllers, bad weather and a network running at full capacity amid high demand.
