Lufthansa announced record profits and revenue for 2007.
The German national carrier said post tax profits for the year were 1.7bn, more than double the 2006 figure.
During the year, it said that revenue rose by 13% to 22.4bn while its operating profit shot up by 63.1% to 1.4bn.
The figures include, from last July, those of Lufthansa's fully-owned subsidiary SWISS.
The airline group said the consolidation of SWISS has led to synergies of 233m, which "surpassed all expectations."
The consolidation and the expansion of the group had led to a 19.8% rise n operating costs to 22.5bn.
Fuel costs had also risen to 3.9bn, the equivalent of a year on year increase of 505m.
Wolfgang Mayrhuber, chairman and ceo of Lufthansa, said: "It is especially worth mentioning that we have achieved this record result at a time when fuel prices are at their highest, financial markets are full of uncertainty and competition is harder than ever. The course that we have set is one of sustainability."
He said that purchase of a 19% stake in the US carrier JetBlue was to position Lufthansa for when "further liberalisation" of air traffic came about through the EU-EC Open skies agreement.
The airline also had a current order for 170 new aircraft.
Mr Mayrhuber said that despite of the "current uncertainty in the financial markets", the perspectives for the aviation industry were "full of promise."
He said Lufthansa was confident it could continue in 2008 where it left off in 2007.
