TUI Group has agreed to sell its French scheduled carrier Corsair to a German airline investor for an undisclosed sum. The German tourism giant has been looking to offload the airline for years as it doesn’t fit with the rest of the company’s business. Intro Aviation is buying a 53 per cent stake, TUI will initially retain a minority stake of 27 per cent, while Corsair’s employee benefit trust will take a 20 per cent stake.
