Had booked aircoach for 12.16 from Drumcondra to airport. We booked train to plane on Irish Rail. We were on time and waiting for bus at 12.08. At 12.10 we could see aircoach approaching and flagged down but it speeded past us, so we thought that it wasn't our bus and went into live app and our bus was on the way. It was still on the way ar 12.56 !! so we took the next local bus that came along, and it took over 40 mins to get to airport and we had to book fast security to guarantee getting through security quickly and just made boarding with 5 mibs to the gate closing. NEVER AGAIN !
