The deal sees eSky buy the iconic brand from China’s Fosun Tourism Group after five years of ownership following Cook’s collapse in September 2019.
It was confirmed earlier this month Cook had more than doubled the size of its Atol to 215,000 authorisations.
eSky said its existing technology “will allow Thomas Cook to significantly expand its flying capabilities, leading to the integration of 560 airlines, enhancing the available travel options for customers and strengthening the company’s competitive pricing position”.
