Fosun, which held an 18% stake in Cook when it collapsed just shy of a year ago, acquired the Cook brand last November.
The CAA has now granted London-headquartered Thomas Cook Tourism (UK) Company Limited an Atol for an initial 364 passengers.
The OTA’s operations look set to initially span the UK, Netherlands and Belgium, with three domain names affixed to the Atol – thomascook.com, thomascook.nl and thomascook.be.
The three websites feature a holding page, offering interested parties an email sign-up field for more information.
