Passengers should expect flight delays and cancellations at Berlin's two airports Thursday due to a ground crew strike strike over pay, union officials announced.

Lufthansa, Germany's largest airline, warned passengers that up to 30 flights could be cancelled. Air Berlin, the second largest, said departures at Berlin-Tegel airport would be "delayed or cancelled due to the Verdi trade union strike".

Verdi called the strike ahead of new pay talks on Friday. The union wants a salary increase of one euro per hour. Ground crew are currently paid 11 euros per hour.

A similar strike last Wednesday at the airports in Berlin and the one in Hamburg forced airlines to cancel up to 100 flights.
