Earlier this year leisure and tourism company TUI confirmed it would phase out the Thomson and First Choice brands and bring them together under one roof.
The rebranding follows the merger of the group's UK and German operations last year.
PRWeek understands that TUI is looking for a PR agency to cover a range of services.
Lisa Jones, general manager of external comms TUI UK & Ireland, is believed to be overseeing the process.
TUI declined to comment.
