Andy Harrison
He's a good man with a solid record of achievement at RAC where people I know rated him as a boss.
Sure, he doesn't have an airline background, but did Branson in '84, or Stelios in '95?
He is a good leader, a decent manager, City friendly, and because he's not an aviation man, he probably doesn't have too many fixed ideas and will have to listen to the experts around him. So it's up to those experts to brief him properly.
