Despite everything that's gone wrong, and what seems to be gaping holes in the preparation of the staff for the move to T5, I think Willie Walsh deserves some positive recognition for being honest in his statements rather than trying to gloss over what's become a serious issue, and openly admitting that responsibility for some of the chaos has to lie with BA management, which ultimately means him.
Sure, some of it is dressed up in optimism about how great T5 *should* be, but it's a clear admission that BA did not handle this as well as it could have done: 'British Airways has not delivered... the buck stops with me, and I'm determined to make this work.'
Kudos to WW for standing up, being honest, and taking the flak.
With the benefit of hindsight, I wonder if BA should have sought assistance or consultancy from Lufthansa (or the Munich Airport Company) to make the T5 move go smoothly. LH are one of the few European airlines of a similar scale to go through a similar terminal switch in MUC in 2003.
I remember LH moving their entire hub from T1 to T2 at Munich, this a very similar move BA are doing (into a brand new, dedicated terminal), and my recollection is that it went very smoothly.
