Generally management salaries are low and topped up with bonus/share options if challenging targets are met. Don't forget your pension is linked to your pensionable pay, just the basic element. Many nights are spent burning the midnight oil, sometimes for nothing. Plans and business cases put forward have more chance of not coming to fruition than be accepted, sometimes demoralising all concerned.
Compare that to someone who collects a basic wage up to £140,000pa and has a final salary pension of £80,000pa. It is incomprehensible how a carrier can continue to fund this in the present climate. Whilst you would like a comparison between management/flight/cabin crew, lets not ignore this is the big elephant that really needs tackling - the feather nest you're going to lay in when your wings are mantle piece ornaments.
Freeze the final salary scheme as of tomorrow for all and revert to a money purchase scheme - that's what would truly make us a world beating airline in the profitability stakes.
