British travel company Thomas Cook Group said a summer heatwave kept holiday-makers from booking last minute trips overseas and warned that annual profit would come in at the lower end of expectations.
But Thomas Cook said its airline business was growing strongly, particularly in Germany where it had added capacity, as it continues to benefit from the demise of Air Berlin last year, a trend also seen by German airline Lufthansa.
The company denied a report in a British newspaper that it was considering splitting off its airline and selling a stake to an outside investor to reduce debt.

"We have no current plans to sell our airline," CEO Peter Fankhauser told reporters on a call, although he did not rule out a future move.
"We have consistently said that we are open to play our part in the consolidation when it makes sense for our business," he said.
Thomas Cook makes all its profit in the summer when its customers in northern Europe, including Britain, Germany and Scandinavia go on holiday, mainly to warmer destinations in southern Europe, such as Spain, Turkey and Greece.
But a heatwave has affected the company's ability to extract higher margins from late bookings.
"Because of the weather, we have now in the market more capacity to sell for the late business," Fankhauser said.
Thomas Cook said that as a result, full-year underlying operating profit would now be at the lower end of market expectations, from a £323 million to a £355 million range. In its last financial year, the 12 months to September 30, 2017, it made £330 million.
Jefferies analysts, who rate Thomas Cook a "buy", cut their forecasts for annual earnings per share by 10 percent, but said the story remained positive in the longer term.
"This year's abnormal weather does not affect our longer-term investment thesis, which remains unchanged," they said.
