His departure comes after the Marseille-headquartered line celebrated its best-ever month in terms of bookings and passenger numbers in the UK in February.
Maillard has led a UK-based trade sales team, which currently includes business development manager Danny Giles and Vladislav Saveliev in recent years after joining the line in 2018.
International sales director Stephen Winter hailed Maillard’s effort and passion, saying: “Nabil has been that bridge between the UK and the French markets. Where Ponant is today in the UK is down to Nabil’s presence in the field – but he wants to try something new.”
