From the BBC:
"Fresh BA strikes look set to go ahead after a High Court judge overturned a ban on industrial action.
BA was granted an injunction on Monday after a judge ruled that the Unite union had not reported results of its strike ballot correctly to members.
But Unite appealed against the decision and a judge ruled in its favour.
The first strike had been scheduled to begin on Tuesday, ending on 22 May, with the three further strikes planned to begin on 24 May, 30 May and 5 June."
The chaos and irrevocable damage to the BA brand is set to resume.
