If I were you, I wouldn't be worrying.
Firstly, there is the court date on 1st February over whether or not the 'imposition' was a breach of contract. I personally suspect that BA will win.
Secondly, we are a long way from BASSA having a strong enough 'yes' vote to be able to conduct any meaningful strike action. The propaganda campaign to instill a sense of understanding that this is not a game and hence a sense of personal responsibility and understanding of what a 'yes' vote will mean to the individuals has only just started. The kid gloves that the company has been using to daet are only now starting to be removed - there will be more to come, hence my comment about a strong 'yes' vote being a long way off.
Thirdly, any strike call that may be made would in all likelyhood be in the first week of March, and over within a week tops, meaning any mid March booking should be secure.
Hope that helps - all imho.
