With so many of the National Airlines going bust, It's not really much wonder Bloody Awful is playing hard ball, it's trying to keep itself going. It employs many thousands, and the cabin crew are paid better than many other airlines, so I reckon they should suck it up and be thankful they've got jobs in this economic climate.
But as Hugh says, it's gotta watch it's back, plenty of other carriers wanting their blood.
Cheers, HG.
