Well I'm buggered if I know any. Rarer than rocking horse s%&*.
Come off it - it is totally ridiculous to suggest that as you don't know any decent managers, that there aren't any.
There are whole swathes of the organisation that are vital, but that those at the front line never meet (whether they should know about them and meet them is a different matter however...cohesion of the organisation would suggest you should know them).
Who for example manages GDS relationships & infrastructure? Outstation safety audits? Lease financing?
Last time I heard, those areas were all working very well and were essential to the operation. Chopping 3 layers of management out totally is simply living in cloud cuckoo land.
None of which rules out the benefit of the blank sheet of paper option...aside from the fact that running an airline is not simply processing passengers, loading the aircraft and flying it from A to B with customer-facing staff (which some people on here seem to believe IS the sum total of what an airline does).
