On 3rd September the 700 service from Leopardstown to the airport at 8.55 didn't run. The next service at 9.15 didn't run either even though there was a bus there. This bus didn't leave until 9.45 and took an hour and a half to get to the airport which meant it took nearlytwo and a half hours from the time we arrived in Leopardstown to arrival at the aiport and this resulted in us nearly missing our flight. When we arrived at the airport the driver disappeared and I had to crawl into the hold to get our cases as the bus filled up on the way to the airport. I will never use this unreliable service again.
