MONTREAL — After five years at the helm of Air Transat, President and General Manager Jean-François Lemay will be leaving the airline.

The announcement was made by parent company Transat A.T., which confirmed that Lemay will be leaving his role in a few month’s time following more than seven years in total at the company. Lemay will continue in his current role until Transat announces a successor.

“We respect Jean-François’ decision to take on new challenges,” said Annick Guérard, Transat’s Chief Operating Officer. “I wish to acknowledge his significant contribution to the development and growth of our air operations in recent years, and express my deepest appreciation for his commitment and for the tremendous work he has accomplished.”

During his tenure, Lemay oversaw a number of structure-enhancing projects for the air carrier, including reducing its air costs, establishing a new senior management team, driving growth through the insourcing of Air Transat’s narrow-body fleet, operating the so-called double flexible fleet, and transforming the fleet, which will consist entirely of Airbus aircraft by 2022.
