well ATCO's have not traditionally paid much attention to the revenue side of the business......coupled with a desire to get traffic from A to B as efficiently as possible. Operators will continue as long as the loophole exists.....ATCO's will continue until someone tells them not to.
Speaking as an engineer, superb comment! We've been pressed for years to find revenue streams and plug leaks - didn't realise we had potential revenue gushing out at the coalface and everyone ignoring it!
