The Unite union is taking legal action against British Airways over the removal of travel concessions for cabin crew who engaged in strikes.


Unite said the airline’s action was a breach of European Human Rights legislation.


In a a statement, Unite also said it would provide support to members who had suffered financial hardship


Last week, the union rejected a “final” offer from BA. Union leaders are planning to meet BA executives next week at the conciliation service Acas for further talks to resolve the still unsolved dispute, which has cost the airline £150m and disrupted 22 days of service.


The union has threatened a fresh strike ballot that would be likely to see strikes resume in September following 22 days of action in March, May and June. But the union has seen support for strikes among cabin crew diminish over the course of several votes.


The latest ballot saw 3,419 crew vote against BA’s offer and 1,686 in favour, out of about 11,000 Unite members.
