Tui's airlines business swung to a €17 million loss in the six months to June, reversing a €50 million profit recorded in the same period a year earlier, as the Iran war continued to disrupt global tourism routes and drive up fuel prices. For carriers, fuel ranks among the largest single operating expenses, meaning even modest increases in oil prices can quickly erode thin airline margins.

The Frankfurt-listed group, the world's largest travel and tourism company, said the decline reflected "weaker demand as a result of geopolitical developments and increased price pressure in a market environment characterised by higher fuel costs and additional capacity on the market."

Tui's airline revenue fell eight per cent to €4.9 billion over the period, although turnover increased across its hotels, resorts, and cruise operations. That divergence underscores the advantage of Tui's vertically integrated model, which spans airlines, hotels, cruises, and experiences, allowing stronger-performing divisions to partially offset weakness in others. Group-wide revenue declined six per cent to €5.8 billion, while underlying group profit dropped 27 per cent year on year to €235 million, falling short of analyst expectations of €274 million.

Tui 'Holding Its Own'

"The quarter continued to be characterised by a challenging market environment and ongoing geopolitical uncertainties, in particular the war in Iran, economic weakness in Europe's core markets and consumer caution evident across many sectors," Tui told shareholders.

The group's 'musements' division, which offers tours and activities, was a standout performer, posting a nine per cent increase in underlying profit to €22.7 million.

Chief Executive Sebastian Ebel insisted that Tui had "held its own well in a difficult global environment," citing multiple headwinds affecting consumer behaviour.

"Wars and geopolitical tensions, consumer caution, economic weakness and rising inflation in Europe's core markets – all these factors have influenced consumer sentiment and the timing of purchasing decisions," Ebel said.

He noted that booking activity has been "picking up again" in recent weeks, though holidaymakers are increasingly purchasing tickets at the last minute in an effort to navigate travel disruptions stemming from the Iran conflict.

Shares in Tui fell three per cent to €7 in early trading, leaving the stock down 21 per cent since the beginning of the year.

Investors 'May Need a Holiday'

Derren Nathan, head of equity research at Hargreaves Lansdown, remarked that Tui's investors "may feel they need a holiday" following the disappointing results.

"The weak quarter adds more pressure for a clean landing in the final stretch of the year, and while the runway still remains relatively wide, management is likely to be buckling up for a tricky approach," he said.

The broader travel sector is feeling the strain. On Tuesday, Holiday Inn owner Intercontinental Hotels Group (IHG) disclosed that a decline in Middle East revenue is weighing on its overall growth. The hotel group, which also operates the Crowne Plaza and Vignette Collection brands, reported a 19 per cent year-on-year drop in revenue per available room for the three months to June.

The FTSE 100 company told shareholders it is confronting "ongoing impacts from the Middle East conflict, including some wider disruption to international travel flows."
