The UK-listed travel firm has appointed FTI Consulting to handle its City PR account, moving it from former incumbent RLM Finsbury.
The decision comes after a tumultuous period for Thomas Cook, which appointed new chief executive Harriet Green in July last year following a series of profit warnings and an emergency bank loan of £200m before securing its future in May 2012 via a £1.4bn refinancing package.
As well as the refinancing deal, Thomas Cook also restructured its comms unit last year.
It hired Jenny Peters for the newly created role of group head of comms in November as part of a major management restructure designed to re-energise its business.
Both Peters and Green were formerly at electronics firm Premier Farnell, where Peters was head of corporate comms. FTI also handles the financial comms account of Premier Farnell.
Peters confirmed to PRWeek that the firm had appointed FTI Consulting.
RLM Finsbury previously supported Thomas Cook through its 2007 merger with MyTravel. The agency had handled the group's retained financial brief since mid 2010.
