CL give the travel industry a bad name. Their lack of customer service, terrible attitude and greed during COVID has resulted in a lot of unhappy customers, who I am sure will do their best to discourage others from booking with them. When booking through Skyscanner there will be a number of travel agents offering competitive prices like CL. In my experience a number of these competitors have handled COVID refunds in a far better way. If there is a chance that anything could go wrong with your flight, do your research and book with one of their many competitors offering a similar price. CL will do everything they can to retain any money spent with them, regardless of whether it breaks their T&Cs.
