Lufthansa cabin crew have marched at Frankfurt airport as their 24-hour nationwide strike continues.
All German regions and all types of flights have been affected, with 900 cancellations causing disruption for thousands of passengers.
The UFO union, which represents about two-thirds of Lufthansa's 19,000 cabin crew, argues that its members have had no pay rise for three years.
A Lufthansa spokesman said that the airline had offered to stop fixed-term contracts and halt the use of temporary staff, and a 3.5% payrise.
