The Belgian subsidiary of Lufthansa is cancelling close to 700 flights over the summer holiday period, around 6% of its scheduled flights, to reduce workload and avoid strikes, Belgian media Belga and L'Echo reported on Monday.

Pilot and cabin crew unions of Brussels Airlines planned a three-day strike last month, after complaining that work pressure was too high and that the company has been aware of the situation for around a year, without providing a solution.

No one at Brussels Airlines was immediately available for comment. (Reporting by Charlotte Van Campenhout, Marine Strauss; Editing by Toby Chopra)
