UKinbound and seven other organisations, including Airlines UK and the Tourism Alliance, have signed the letter designed to highlight the importance of international visitors to cities across the UK.
The letter says that UK hospitality businesses, theatres, attractions and inbound tour operators will “struggle to remain profitable and viable if international visitors do not return this year”.
It also points out the disparity between what an international traveller spends during a trip to the UK (£696 on average) compared with a domestic tourist (£239).
