Thomas Cook launched the Cook’s Club and Casa Cook brands shortly before it collapsed in 2019; Cook's then largest stakeholder, China's Fosun Tourism Group, initially acquired the brands, along with the main Thomas Cook brand shortly afterwards.
Goldman Sachs Asset Management then took them on for an undisclosed sum in 2023. Fosun, meanwhile, relaunched Cook as an OTA before selling the brand to Poland's eSky Group in September 2024.
