Air Transat is a Canadian leisure airline based in Montreal, Quebec. As of my last knowledge update in September 2021, it was a subsidiary of Transat A.T. Inc., and it primarily focused on providing vacation and leisure travel services. Air Transat operated scheduled and charter flights to over 60 destinations in 25 countries.
However, please note that the airline industry is subject to changes, and there may have been developments after September 2021. For the most current and accurate information about Air Transat, I recommend checking the latest news or visiting the official Air Transat website.
