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...
