My money is on the surcharge rising again to pay for the fine!
As a BA worker I can see the company got what it deserved. "We" broke the rules and as such were punished. Shame the fine was at the expense of any employee reward scheme we were due - mistakes of a few cost a lot of us a lot of money.
I'd just like to see the money go to good use, perhaps in aviation safety research or airport safety improvements. Can't see that happening though.
