We use air coach 4-6 times a year to and fro Belfast / Dublin and have always been happy with the service. Our recent trip on the 12th Dec from Dublin, however, didn't feel up to the same standard. There was no WiFi on the coach and it felt somewhat uncomfortable in the wet weather as the driver for some reason only used his wiper blades from time to time with the large windscreen more often covered in spray. At Dublin airport the staff were quite brusque when asked where and when the coach was - after a long flight and early in the morning, this wasn't the best of customer service.
