Unite is to continue its legal battle with British Airways this week, as it lodges an appeal with the High Court over the withdrawal of travel perks from striking cabin crew.
Some 7,000 cabin crew members who went on strike earlier this year have had their travel concessions removed.
The union also plans to return to the courts on October 11 and 12, when Unite will claim at the Court of Appeal that a reduction of crew levels was a breach of contract.
The cutting of the number of staff on board was the initial trigger for the dispute.
In a third stage of the legal wrangle, Unite is also planning to head to the European Court of Human Rights this month, over the UK government's interpretation of ballots on industrial action.
