Cummings will bring 35 years’ travel industry experience to her new senior worldwide travel expert role with the tailor-made specialist.
Her experience spans agencies, hotel groups and DMCs, with Cummings spending the last 20 years working with luxury operators.
The move also marks her return to travel after an enforced career change owing to the pandemic.
"I really missed the travel profession so I am thrilled to be back, and I cannot wait to share my experience," said Cummings.
Neil Sealy, Exsus head of trade sales, added: "We have been incredibly fortunate to be able to welcome a number of very talented people to the Exsus team over the past few months, and it is with great pleasure that we now welcome Christine.
"We have seen a tremendous increase in enquiries and bookings as the world opens up again, almost all of these from travel agents, and it is paramount that we remain ‘ahead of the game’ and ensure that we are in a strong position to handle these enquiries with the level of service that would be expected from Exsus.
"The recent additions to our excellent team have helped us ensure that we can continue to live up to the high standards that our valued travel agents expect and deserve."
