Yes but one would argue that just because it was the only airline recruiting two years ago people shouldn't have joined expecting a vast salary increase down the line. If they could have earned more elsewhere, be it away from flying then it is a free market. Again some people save before learning to fly.
Sadly the " my loan costs me £800 a month so I deserve more money" is another symptom of the buy a job quick fix craze which is destroying this industry. The chap who took the flybe job with crippling repayments may well have been better served not being in the situation were he is in so much debt. Plenty of people have qualified without these horrendous figures, but by saving and learning to fly as they go.
I can't stress enough that I am on the side of a pay increase. I just take issue with some of the reasoning I see here.
