Lufthansa's catering subsidiary LSG said Wednesday it plans to slash 2,400 jobs across Europe as it seeks to trim its operations to cope with falling prices and a rapidly changing market.

Some 1,700 of those cuts would be made in Germany, with the restructuring to be completed by 2021, a spokeswoman said.

"The market has changed very quickly and very dramatically," she said.

In a bid to cut costs, airlines are increasingly looking to other options for their meals.

At least three sites in Germany would be closed as part of the planned restructuring.

Besides supplying Lufthansa, LSG caters for international carriers including American Airlines, Thai Airways and Emirates.
