Apparently 76% of crew turned up to work today.
And latest from BA:
May 30-June 3 schedule
We will be increasing our flying schedule during Unite’s threatened five day strike (May 30, 31 and June 1, 2, 3) after more cabin crew than expected decided to work as normal during this week’s industrial action.
Our Heathrow longhaul schedule will be increased to more than 70 per cent of flights (up from more than 60 per cent this week). Our Heathrow shorthaul schedule will increase to more than 55 per cent of flights (up from more than 50 per cent this week). We will continue to fly to every shorthaul destination on our network.
Services from Gatwick and London City airports will continue to operate as normal.
