The worst outcome I think would be a last minute deal between WW and BASSA.
He needs to let the strike go ahead, then destroy the union's leadership once and for all. Only then will people start to trust BA again.
That's the opinion of several frequent flyers from outside the industry that I've chatted to anyway.
As long as BASSA sit in the background with their finger still on the IA trigger, people will book elsewhere.
Let's hope it goes well for all the hardworking and conscientious crew members out there.
