I take the air coach all the time (30x a year) because unfortunately they have a monopoly on south Dublin airport transportation. They’re ridiculously stringent and rude, and wont let you on a different line/time if your flight is delayed. There is “flexibook” at extra cost, but air travel is inherently unreliable re timing and you should not have to pay extra just in case something happens with your flight. Today the driver forced me to put my backpack under the bus citing “safety reasons” which were invalid. He singled me out, with all of the explanations and “rules” given being broken by the vast majority of other passengers with no comments. He also made very passive aggressive statements to me while trying to solve the problem HE created. It is also ridiculously expensive for no reason (18.50 for a return to Leopardstown is daylight robbery) and I’ve rarely had a driver without an unnecessary attitude. Unfortunately I do still have to use the service due to its monopoly, but begrudgingly so.
