Here are some hpothetical figures
An airline pilot flies ~850 hrs per year, ie that is the amount of time that they are producing income for the company.
If said pilot got a $20,000 pay rise, this is an extra ~$23.50 paid per flying hour. So with two crew getting the same payrise lets say an even $50 per hour more.
One a typical Aussie flight of say 2hours that is an extra $100 so less than $1 per passenger to pay for the payrise of $20,000 for every pilot.
I am sure a lot of pilots would love a $20K payrise and the $1 per ticket would not even be noticed...
Very simple analysis and yes it does ignore some other costs but, as a passenger, an extra $1 on my ticket to have happy pilots is more than worth it!
Just my worthless 2 cents...
(Don't shoot me down for the figures, they can be out by a factor of five and it means nothing to the average passenger).
