Thomas Cook Group plc is a travel company created on June 19, 2007 by the merger of Thomas Cook AG and MyTravel Group plc.

At flotation on the London Stock Exchange 52% of the shares in the new company were held by the German mail order and department store corporation Arcandor (former owners of Thomas Cook AG) and 48% owned by the shareholders of MyTravel. On June 9, 2009 Arcandor filed for bankruptcy.

The merger, which was backed by 99.9% of shareholders, took place through the formation of 'NewCo' which effectively purchased MyTravel and Thomas Cook and was then listed on the London Stock Exchange under the name of Thomas Cook Group plc (LSE: TCG).

It is a constituent of the FTSE 250 Index.

It was announced on 8 October 2010 that Thomas Cook Group was to merge with The Co-operative Travel to create the UK's largest travel network.

The company was founded by Thomas Cook, a cabinet-maker, in 1841 to carry temperance supporters by railway between the cities of Leicester, Nottingham, Derby and Birmingham.
