Figures quoted for flexicrew pilots are incorrect. Some months may be that much, but averaged, considering we can only fly 900 hours MAXIMUM a year, on £43 an hour = £38700. After tax, paying student loan as well this equals £2200 a month. Minus £1000 (minimum) loan repayment = £1200. Add on a couple of standbys a month at £150 a time and you may just get £1400 after tax.
Please note this is average, yes the guys you've spoken to may get more throughout the summer, but it's got to average out somewhere, so just wait for those months where you only get 40 hours.
As an SFO on the Flexicrew you take £58 per hour. This works out at £2800 a month + standbys.
Also, we have to pay for our own medicals, own LOL and term insurance, own uniform and only get £20 for a nightstop - which just about pays for a beer in CDG.
