Deutsche Lufthansa AG is reporting a net loss for the first half of the year due to factors including a strike by pilots and airspace closures caused by ash from an Icelandic volcano.
Lufthansa said Wednesday it had group losses of euro104 million ($135 million) in the January-June period -- compared with a loss of euro178 million a year earlier.
Lufthansa didn't give second-quarter net earnings ahead of its full report Thursday. But it reported a quarterly operating profit of euro159 million -- triple last year's euro52 million.
The company says second-quarter revenue was up to euro6.9 billion from euro5.2 billion. First-half revenue was up to euro12.6 billion from euro10.2 billion.
The Lufthansa Group also includes Swiss International Airlines, Austrian Airlines and Britain's BMI.
