German airline Lufthansa is to cut 3,500 jobs as it seeks to cut its administrative¹ costs by a quarter.

德国汉莎航空将裁员3500人以求降低管理成本。

The airline will cut those full-time² jobs in administrative departments worldwide over the next few years.

The news came as its loss narrowed to 379m euros ($498m; £308m) in the first quarter, from a loss of 507m euros in same period of 2011.

Lufthansa blamed higher fees and taxes, even as quarterly revenues rose by 5.6% to a record 6.6bn euros.

These included an air traffic tax imposed in Germany and Austria and the costs of carbon emissions³ trading in Germany.

"Higher taxes, fees and charges put a massive strain on our quarterly result," said Christoph Franz, chairman of Lufthansa AG. "We cannot wait until politicians also recognise the damage that one-sided taxes and charges do to aviation and to Europe's reputation as a place to do business."

Lufthansa said that fuel costs had risen by 304m euros in the past year.

Last month, Lufthansa completed the sale of loss-making UK airline BMI to IAG, the company that owns British Airways⁴ and Iberia.
