Apparently it is not possible to give zero stars here- what a pity. The bus arrived this morning, apparently at the right time, but the driver told me that his was an earlier bus running late and that my pre-purchased ticket was for the next bus, a few minutes behind, and so he refused to take me. He took two other passengers that did not have tickets at all and who had arrived after me. I waited a further 50 min before giving up and getting a Dart train and then a taxi, which was the only sure option left by that time. There is no live info available at the stops for Aircoach, unless you have their app (but what traveller wants an app on their phone for every bus company they ever use?) and my stop was not even indicated by a clear sign. Difficult to use even for locals, let alone tourists and non-English speakers. Please try to find any other option than Aircoach- only use them if you're desperate, would be my advice.
