I booked the transfers through my Ryanair flight booking. I discovered that AirCoach had booked non refundable travel arrangements dates / times on reverse dates and non-matching times with my Ryanair dates/times. Although I emailed Aircoach to question and possibly remedy this I received no acknowledgment or response from AirCoach until after I had returned from my weekend visit to Dublin. To avoid not being able to use the transfers I had paid for with Aircoach I took the precaution of booking transfers on the Dublin AirPort Express Service and this worked reliably and well. So I’ve wasted booking by Aircoach they failed to respond to my email query in a timely and useful manner and I lost the money I paid them. Of course I will never book with Aircoach again and recommend travellers to use the Dublin AirPort Express service instead. The worst of it is Aircoach failed to respond or even acknowledge my email in a timely manner.
