I don't doubt the figures for a moment, but I guess, and I haven't checked, so if I'm wrong, my apologies, that these are the "published rates".
They are, and I clearly stated that in my post. My point is that it's a monumental task just to make up an extra £1m in revenue even at list prices. By the time you factor in discounts and expenses, it becomes even harder to overturn the current £1m a month in losses the airport is making.
