For the first time this year while travelling abroad the Killiney route now only travels every two hours on the hour. The last bus finishes at 23.40pm. The Leopardstown service finishes a little later. Operating every half hour on the hour. Your website says services operate 24/7 but this is not the case for some services. When I came back from holiday the stairs leading to Zone 20 to catch my bus was not working. Should this be the case again, is there something that can be done so people can use an alternative stairs to get to Zone 20 in order for people to make their way from the Airport in order to make the next part of their journey home. Also is there a possibility that the last bus could be a little later ?
