On the 30th January 2024 I travelled on the 5.50 AM coach from Derry to Dublin Airport. The bus was extremely cold and the driver said he had the heating on but this certainly wasn't the case. The bus pulled in to Belfast Airport at 6.14 AM and didn't leave until 6.55 AM. A few points on this stop....1. The length of time sitting at Belfast Airport is an unnecessary waste of time, other company's have a quick stop of 10 minutes. 2. Advised by the second driver that the heat was broken. 3. This second driver showed no consideration to me being on the bus (alone), turned up the radio quite loud and stood outside smoking so he could hear the radio, whilst I'm inside trying to get some sleep as I had an early start and had 2 flights to get that day. When I asked both these drivers any questions (i.e. heating, when we are leaving Belfast Airport, etc.) they were both extremely rude. These drivers both had English accents. It was only when we arrived in Belfast centre that we meet our third driver - the lovely Summer. I asked her why we were so long at Belfast Airport, she inform me it was for a tea and toilet break. I told her the second driver mentioned nothing of this to me. She was quite shocked!! She kindly gave me the time to use the toilets at the Belfast bus station, turned on the heat in the bus even though the other 2 drivers said it was broke and came out of the bus at Dublin Airport to wish me a safe onward journey...She was truly an angel and an excellent driver...I wish she had been driving the full journey, her customer service is exceptional. The male drivers are an absolute disgrace....rude, unhelpful, inconsiderate. This was my first and last experience with Aircoach and I certainly will not be recommending your company to anyone in the future. (I would hope that Summer in Belfast Centre will receive my praise because she is excellent at her job).
