There was an Airport PUC until c.2006. I think paying DAA was suggested by the unions. It was originally PPJ, when I first worked there it was 40p and you charged the passenger £1.20, that increased to 50p/£1.30 before the annual subscription was introduced. Airport PUC was €1.50 when abolished.
What we have now is drivers driving to the airport empty to join the rank and drivers who drop off passengers driving back to the city empty... which makes little sense. Added to that, DAA refuses to facilitate passengers who don't want to use the rank (often due to bad/unpleasant experiences), practically telling them that they must pay whatever the licensed driver demands or fukk off and walk.
