I'm trying to visualise an airport run as a low-cost operation. Just imagine things such as paying an extra £5 to go to the front of the security queue, £1 to have your shoes x-rayed, £2 to use the little train between terminals (seeing as those terminals would be used by the competition), £1 to have your passport checked at arrivals, £2 for a baggage trolley, 50p to stand at the best part of the baggage carousel...
....£5 an hour to consume a 79% Nitrogen/21% Oxygen mix during the time you are in the terminal, 8p per step in the terminal to compensate for floor erosion, £5 per visit to the toilets....
If MOL really wants to own an airport and play at being god/baa then let him build a new one. Can I suggest somewhere in Ireland?
