Kat Hulatt becomes trade support executive having previously worked in the line’s call centre, while Janna Thomson returns to the role of inside sales manager.
She has past experience of the role having provided maternity leave cover as inside sales manager last year.
Thomson leaves her former customer services manager role with Celebrity for the full time world of sales "due to popular demand from agent partners", the line said.
On the road, Michael Young-Richards is now the regional sales manager for the North West and joins from Do Something Different where he was a business development manager for more than two years.
The score of recent appointments also saw Valerie Murphy join as strategic account manager in Ireland earlier this year.
Nicola McNeish, head of sales, Celebrity Cruises UK & Ireland said: “These appointments demonstrate our continued investment in talent. As part of our ongoing commitment to agents we’ve increased the amount of office-based support available, in addition to new energetic sales team members throughout the UK and Ireland.
“I’d like to wish Michael, Valerie and Kat the best of luck in their new roles, and warmly welcome back Janna to the team. With the launch of Celebrity Edge at the end of this year, our sales team are looking forward to working closely with agents to showcase modern luxury cruising at its best”.
