WW is addressing the troops as we speak, no doubt appraising them of the seriousness of this situation.
BA should have 1,000+ volunteer replacement cabin crew fully trained within the next week or so.
800 out of 1,100 LGW cabin crew have signed up to work over any industrial action.
30 wet lease aircraft are available to BA with cabin crews to cover a significant amount of short haul without touching the volunteers.
I really don’t see any strike having significant impact on most operations. The Union is powerless.
