Ruth Marshall, managing director of RCL Cruises Ltd, and Garry Wilson, chief executive of easyJet holidays, join the board as directors.
Managing director of Tui’s northern region Andrew Flintham, meanwhile, rejoins the board, also as a director.
Stuart Leven, who left Royal Caribbean Group last week after eight years, and Tui commercial director Richard Sofer make way.
"We’re delighted to welcome Ruth and Garry onto the Abta board for the first time, and to welcome Andrew on his return to the board," said Abta chair Alistair Rowland.
"All three individuals have outstanding backgrounds in travel.
"RCL, Tui and easyJet holidays demonstrate the wide range of businesses within Abta membership, and are essential suppliers to many other Abta members.
"There has never been a more important time for different parts of the travel industry to work together behind a single organisation to carry our case to government, and to shape the future of the industry as we emerge from the pandemic."
Rowland added: "I would like to thank Stuart and Richard for their invaluable contributions to our board discussions over the recent years, as we have worked to steer Abta members, and Abta itself, through the biggest crisis the industry has faced."
