Aircoach is an excellent service and drivers are always nice... but I didn't give it 5 stars because when I booked 4 of us on Ryan Air, I had the choice at that moment to purchase return Aircoach tickets from Belfast to Dublin. I knew my arrival time in Dublin, however, at the time of booking Ryan Air and Aircoach, I did not know what time I would be leaving Belfast to come back to Dublin. I had to, unfortunately, purchase 4 more return tickets as no one at the Aircoach could help me with the already made purchase and told me when booking Ryan Air and Aircoach I should have put the return time... and therefore there was nothing they could do?!?!?!?!? Lesson learned.... when that opportunity comes up again, I would not purchase Ryan Air and Aircoach tickets on the Ryan Air site. Ryan Air said it was Air Coach and Air Coach said the return time was supposed to be done when I purchased it. I was able to put a return date.... just didn't know a time, as it was months away. But a month before I traveled I tried , and I, unfortunately, lost the 4 return tickets!!!
