Caron, who has held senior leadership roles across product, purchasing, cruise and distribution during her 24-year Tui career, left the group at the end of September, Tui confirmed.
It came a day after it was announced Tui UK and Ireland managing director Andrew Flintham would succeed British Airways Holidays managing director Claire Bentley next month when she retires.
Tui said Caron had been “a key member” of its markets and leadership team over the past seven years.
