Sony,
You have only made two posts on PPRuNe and are a relative newcomer.
Your first post was most insistent that there was no evidence to suggest a big announcement was to come from GB/BA. Your second post now states that there was a meeting (somewhere), that you are privy to, and that the outcome of that meeting is that GB is to go it alone.
I certainly hope you are sure of your facts because suggestions like this can have a major and unsettling impact on employees of both these companies.
Perhaps you would elaborate further on this meeting, who attended, where it was held and how you know about it!
