As a regular user of Dublin Airport - and of course buying a travel 90 ticket - to get me all the way to Drimnagh for 1.90, I have in the past directed tourists onto the 41 instead of boarding the Airlink, and have also pointed out that it is cheaper to buy an unlimited travel 90 minute than a single fare into town. They are going to get ripped off on their visit to Dublin anyway, and it should not start with the Airlink, or indeed Aircoach for that matter, when they can get into town for a quarter of the price, the 41 only takes about ten minutes longer.
