There might only be a handfull (I see a bit more than that though) of pilots "bitching" about the worlds most admired airline (ohhh yes!) - but those "few" represent a hole lot more, mate.
About walking the walk.. There a many ways to do that 2. Some guys, and more than a few, has already done that - dont think anybody want to refuse that fact anymore - other are about to do (knowing thats relative). Hot air.. well for some - sure - for others - dont think so. A bunch dudes simply havnt got the guts and are too stuck into walking behind Nigel, and have become to dependent on the money thing, most just dont admit it or have become ignorant to the fact, that thats what they actually do. Mate, I see them all to often, and its nasty!
The greener paths are out there - thats a fact! Good luck to the ones who are still free.. Walk the walk
