I travelled last week from Derry to Dublin. The journey lasted c. 4 hours. There is no toilet facility on board the coach. I requested that I could use the toilet facilities at Belfast. I was not allowed to do so as the coach was "leaving immediately" Another passenger requested the same at Belfast (outside Europa) but was told there was no option. I desperately needed to urinate and my only option was to find a discarded drink bottle left behind by another passenger and pee into it. Hopefully I do not pick up a uti or sti from the bottle, given that another passenger had been drinking from it. Luckily I am a male and this was physically possible. The female passager did not have this luxury. I made sure I did this discreetly, this was possible as there were only about 20 passangers on the bus at the time. All other services from Derry to Dublin (Translink and McGinleys) have a comfort break halfway. Surely this is a breach of consumer rights or health and safety regulation. I will not be using Aircoach again.
