I've just started with EJ and wont have a full months sector pay until the end of next month, I think around £750 per month before tax wont be far off the mark.
And your on 90% of your basic salary for the first six months, and you wont get paid until you have passed the type rating course if your TRSS, six weeks without salary is the best part of another £4000 on top of the £23,000
Ouch it finantially hurts!!
