I booked an aircoach around around 4am on Westmoreland st Aug 19th; coach was 10 mins early and drove off as I arrived. I hopped into a taxi that drove me to the next stop on O'Connell st where the driver was struggling with telling about 15-20 people they couldn't get on the bus and only people who had prebooked could get on the bus. If a bus is due to be at a stop at 03.57 am, it shouldn't be pulling away from the stop before that time. I could have been late for my flight had a taxi driver not take pity on me when he saw me chase after the bus. I would be reluctant to book aircoach again. Too few buses running before 6am.
