The Financial Post reports in its Tuesday edition that Flair Airlines has the highest number of complaints per 100 flights of all the major airlines in Canada, according to the Canadian Transportation Agency. A Canadian Press dispatch to the Post says that between April 1, 2022, and March 31, 2023, Flair saw an average of 15.3 complaints per 100 flights according to the report published in late April. Sunwing Airlines came second at 13.8 complaints per 100 flights, and Swoop was third at 13.2. Meanwhile, WestJet had 6.6 complaints per 100 flights, Air Canada had 4.3 and Air Transat averaged 3.3 complaints. Flair saw four of its leased planes seized in March because of overdue payments, causing hundreds of cancelled flights. John Gradek, a lecturer at McGill University's aviation management program in Montreal, theorized that the debacle for Flair was a symptom of cash-flow issues. He said Flair had overcommitted itself and passengers were complaining about issues related to compensation. This dealt a blow to the airline's reputation, he said. However, as demand has crept up, Prof. Gradek said Flair is charging higher fares and therefore is likely generating more revenue.
