You cannot take average salaries like that chart shows and compare that with new starter rates. You are comparing apples with pears. Plus virgin figures do not show the allowances they are paid as at Virgin they get paid those in cash. Trust me the starting pay for Virgin is more than £11000. The allowances are more than 2.40 ph.
If you take a quick look at the average pilot salaries on the other side of your chart you will see exactly how misleading these figures are.
