Hawke said Cosmos and Avalon would use the UK government’s traffic light system to inform its decision making, taking into account its plans to review the green, amber and red lists every three weeks.
"Our intention will be to operate our tours and cruises, where operationally viable, to destinations on the green and amber lists which are accepting international visitors," said Hawke.
Hawke said the brands were studying "a range of criteria" to inform decisions on which tours and cruises are viable, and which may have to be delayed.
