In its latest three-weekly operational update, Tui has revealed it will not operate to Turkey until 30 September and will not reinstate some destinations in Spain until 31 October.
The operator’s Lakes and Mountains programme, meanwhile, will not resume in Italy, Austria and Slovenia until the end of October.
Some winter sun destinations like Sharm el Sheikh are provisionally set to resume in October, but Tui has said it will not operate to those countries that remain on the red list.
Tui added: “We won’t take any customers to red destinations or those which require quarantine on arrival, unless this can be foregone by a Covid test.”
