World Cup passengers and a string of takeovers have helped boost Lufthansa's operating profits by 17% in the first six months of 2006.
Germany's national carrier made a 297m euros ($373.9m; £203.3m) profit on sales of 9.6bn euros.
The firm flew thousands of football fans in and out of Germany for the month-long tournament.
It has also taken over Swiss International Air and added to its Eurowings group.
Lufthansa's net profits were 85m euros, compared with just 200,000 euros a year before.
But although the performance was better than had been expected, shares in the firm dropped 1%.
Lufthansa said it now expected its operating profit for 2006 to beat last year's 577m euros.
The announcement came despite expectations that fuel costs would rise by 22% over the year.
The carrier is targeting operating profit of 1 billion euros by 2008.
It is in the process of expansion as it fights the threat from low-cost rivals in Europe such as Ryanair.
