Trouble is, the production/refit line set up costs are pretty much the same wether you're buying seven, seventy or seven hundred.
Let's say set up is £50 million and your cabs have a standalone price of £25 each.
10 cost £30 mil each.
50 cost £26 mil each.
500 cost £25 mil each.
Airframes get cheaper the more of 'em you buy. So the quoted figures are apples and oranges comparisons.
As for wether AW are giving us value for money....
