The launch last November was the earliest Tui has put its summer holiday programme on sale. The operator says it will add a further 2,000 hotels bookable for summer 2020 later this month.

Tui said the move came in response to consumer behaviour, with more customers – particularly families – wanting to book earlier.

Its launch was complemented by a range of sales initiatives, including free kids’ holidays and low deposits, with a new direct debit scheme also now available.

More than 60% of Tui’s summer 2020 bookings from Britons are for mid-haul destinations such as Cyprus and the Canaries, while Florida has proved popular for long-haul Disney breaks.

Some 15,000 passengers, meanwhile, have already booked to go to Tui’s 5T platinum hotels. Greek islands including Rhodes, Kos and Zakynthos have also proved popular.

Richard Sofer, Tui commercial director, said Tui took the decision safe in the knowledge there was ready demand for beach and cruise holidays.

“People are in the market to book their perfect holiday. By booking early, customers can secure their favourite destinations and ensure they maximise value for money.

“We have seen a really positive response since launching our programme even earlier than usual and we are pleased to be adding further hotels to our 2020 summer offering.”
