LONDON/MONTREAL—Nikoleta Dodova is among a growing number of dissatisfied airline customers. Having bought her mother and niece airline tickets from Sweden to Macedonia last year, their flight was cancelled and they ended up at an airport over two hours away. She is still waiting for compensation.
Official data from regulatory agencies shows complaints against airlines have reached, or neared record levels in countries like Canada and Germany over the last year since COVID-19 restrictions lifted and travel restarted.
