We travelled both ways on our recent trip to Dublin. The journey to the city centre was fine! Unfortunately our return leg to the airport was disrupted by a large scale planned city centre protest. Despite us having booked our tickets two weeks in advance, Aircoach did not warn us about this and the alternative arrangements since the coaches were being diverted. In the end, with no coaches arriving we jumped on a local bus. We contacted Aircoach to complain and give them feedback about the lack of warning. They acknowledged they ideally should have warned us. Thankfully they refunded the cost of our return tickets. Hopefully they will warn folks in future.
