As of next year we have to pay the newly introduced aviation tax on our reduced tickets as well, which makes commuting more costly.
Actually up to 2400€ of fringe benefits per year it is tax free, however everything above will be taxed.
And of course our retirement age is 67, which begs the question how a pilot will survive the two years between forced end of contract at 65 and retirement age, after all we are not allowed to fly commercially past 65.
