This could very well be part of BASSA and the militants plan to use "guerilla tactics" against BA and its customers as threatened earlier.
I have no doubt that BA and its employees will be anticipating these sorts of actions and will take immediate, firm and appropriate action.
The militants would serve themselves well to simply return to work as professionals and not draw attention to themselves. Unfortunately I believe there are a few who will find that sort of reasonable behavior quite impossible.
The majority of Cabin Crew and BA management will have no tolerance as BASSA may soon discover.
