I flew out from Dublin Airport last week and the queue for security was nuts. Both security queues were starting back in the check in area.
It certainly used to, just shy of O'Connell bridge before heading to busaras, but it's a few months since I've been on it. There's nothing mentioned on the dublin bus website about it stopping there.Does the 748 bus from Heuston to the airport stop for pick-up on the north quays?
Or Luas to Connolly and get the 747 (or 748 which may also pick up there). But if you're doing this then you may as well just get the 748 for €6.You could in theory hop on the LUAS at Heuston Station, get off at O Connell Street and take the 16A or the 748 or the Aircoach bus to the airport.
