I would not worry about the salary too much, at the end of the day you will have served a proper hands on apprenticeship with a well respected aircraft engineering company, that will put you way above the droves of chaff being churned out by the numerous aeronautical colleges that deliver so called engineers that are neither use nor ornament, they may have the paper qualifications but they are to be brutally honest unemployable in the real world, yout taking the right route, best of luck.
