85,
I could stand corrected but I'm not sure salary is a negotiating point for an interview for an apprenticeship; I started on £25 week (before stipend referred to above) and managed digs with three meals day (packed lunch), washing etc for the full 7 days and had £9 left for Marathons (Snickers) and other tooth rot (all pre-beer drinking days). Moved soon after to other digs that were not as good and more expensive.
Anyway, good luck to all would-be apprentices; for all the moaning you may read - some of it from me - it is not a bad job. You'll get to work on A300, A330, A320, 757/767 and soon 787s; I had Bristol Britannias, 707/720, 737etc to contend with (and I loved it).
