Willie will never resign, he will have to be pushed. Martin Broughton, as chairman of BA, ought to have, to justify his own huge salary, someone in reserve at all times who he can replace the CEO with should things not work out.
And with everything (including an inch or two of snow, gone within 12 hours) seeming to bring the complete BA operation grinding to a halt, it is obvious that every week WW stays on instead of someone more effective, it's another few tens of millions more down the drain. And this includes someone who can tell BAA, as a BA supplier, nothing more, exactly what they have to do (preferably in words of one syllable and 100 db), rather than wiffle-waffling along with their excuses.
As I've said before, does MB not have Barbara Cassani's phone number ?
