The group on Wednesday (14 May) reported a pre-tax loss of €207 million (£174 million) after taking into account the late Easter, which did not fall during this period.
Tui said this shaved €32 million (£27 million) off its second quarter result. This compares with a loss of €189 million (£159 million) during the same period last year.
The late Easter meant 2.6 million guests travelled with Tui in the second quarter, 200,000 fewer than in the previous year.
In Tui’s Northern Region, which comprises the UK, Ireland and Nordic countries, underlying losses amounted to €182 million (£153 million), compared with a loss in the previous year of €165 million (£139 million).
Tui Group chief executive Sebastian Ebel said: "The environment was challenging. And the second half of the year will also remain demanding for the overall economy in Europe.
“Our focus is now on the important summer business. We are offering more and more products in more destinations for existing and new customers.”
Ebel added "travel agencies remain an important partner and distribution channel", and said Tui was expanding its tour operator business and travel agency sales, as well as sales through its own app, with its "dynamically compiled product offerings”.
Tui closed winter 2024/25 with a 2% increase in bookings, with average prices up 4% and “good last-minute business”.
A total of 5.5 million bookings were received, up by 2%. The Canary Islands, Egypt, mainland Spain and Cape Verde remained its most popular short-haul and medium-haul destinations, while Mexico, the Dominican Republic, Thailand and the United Arab Emirates were the most important winter destinations.
For summer 2025, Tui said its strategy would focus on “growing dynamically packaged travel, securing margins and reducing cost”.
“Due to the later Easter business in April, a later booking behaviour can be observed," Ebel continued. "In a highly competitive environment with capacities remaining unchanged, incoming bookings are slightly below the previous year’s level at -1%. Average prices are up +4%.”
Tui stuck to its previous forecast of an increase in underlying full year profits of 7% to 10% “driven in particular by expectations for summer 2025”.
