The original question was "Value for money?"
That's a subjective judgement on the part of the customer. A round of golf with a top professional for a hundred quid might be seen as excellent value by someone keen on golf, but not by me.
If you're selling goods you need to offer them at a price which your customers see as value for money or they won't buy.
Stelios knows the answer. He doesn't charge everyone the same price, he markets his product and sets his prices so he gets good load factors. Some people will have paid a lot and some a little for exactly the same product. If the airports were somehow able to take a leaf out of his book they could up their revenue. They know when the scheduled traffic is due in and out so why not fill in the gaps? Cardiff manage it, they got me in 15 minutes before Concorde! Can't remember how much it was, around 13 or 14 quid? In my book that was good value for money.
