Service worked perfectly on the journey from Dublin airport to Drumcondra on Sunday 29th October but the return bus journey was very disappointing. We arrived 15 minutes early to the bus stop for our 17.53 booking. A bus flew passed without stopping at 17.45 (presume this was an earlier bus that was late??) and then another bus did not arrive until 18.15 so no bus at 17.53 or 18.00. It is stressful when you are going to the airport for a flight and you don't know how long to wait or pay for a taxi. There was no number to call as they are closed after 5.30. I think an app with realtime arrival times would improve the service. I would question whether to use this service again.
