Airline reviews

Seats were less comfortable and tight from Newark to Dublin, than my second flight ( small segment from Dublin to Lyon). Movie audio was with frying sound overall. Yet the worst was as follows: one male, (dark hair , glasses on) from the crew member was so cold and rough, while I remained with constancy polite and kind. Per exple with the noise level I could not hear him at first for beverages, he rolled his eyes at the third times I finally heard him. From the start, loading my small hand bags , he directly spoke to me and said “ I had to keep my shopping bad by my seat, under , while there was sufficient room and I was among the last to sit. I show him the space , his face was always dull, stoic, not welcoming as the usual crew members from any airline companies are. When I think of my experience I liard w Aer Lingus, this is the image that gets back to me. Needless to say that as a passenger and client, I felt belittled since all this happened in front of the surrendering passengers. It s an affront and not a pleasant feeling especially when being traveling which oftentimes involves stress with carrying, and making it on time. I m not happy with the experience I had to be honest and I fly four times a year. Thank you for allowing me to share this statement with your company.

I like Aer Lingus so that is why I’m writing this critique so they can become better. The boarding gate was too small to board properly. Our seats were toward the back of the plane knowing we would be boarding after business class, we moved to that area after business class boarded. An Aer Lingus employee told us we couldn’t stand there. We explained we were the next group to board and wouldn’t even be able to hear when our boarding was called. She didn’t care and was not very professional. The cabin was freezing. I wouldn’t feed my dog the food. We were over an hour late coming into chicago because of weather which can’t be avoided. I asked the crew if they could make an annoucement for before whose final destination is chicago to wait and allow the people with connecting to deplane first. He said there are a lot of people with connecting flights. He said, it doesn’t matter. Well, yes it does. He could have been more considerate of his passengers.

Really helpful staff at the airport and the flight was comfortable with good entertainment options and food service

The flight was delayed by about an hour, but the staff and signs at the airport never actually said it was delayed. We were told we'd be boarding in about 10 minutes, then 20 minutes passed, and were told again that we would board in about 10 minutes. That happened multiple times, such that "10 minutes" turned into an hour.

The seat spacing was good. The food, not so good... typical airline food. 😕

I would face like to have more selections for entertainments overall it was very good. .

At check-in the unmanned machines said QR code was invalid so had to queue for over an hour to check in bags

i used to fly aer Lingus regularly but due to price - poor seating etc i have been using other carriers - i now have aer lingus in my state and the price is always the highest - i have flown to Ireland 11 times in last 24 months and have not used Hartford because of price

Nicest staff I’ve experienced on a plane! Good food, great entertainment, and they gave out little blankets that my kids loved. All in all, great experience.

Unfortunately the flight was delayed for 50 min. Just as we were about to board so that was a drag. The boarding was average. The bag check in process was new to us and efficient. And the flight itself was smooth- basically no turbulence.

Flight was over an hour late. Boarding was really messy with long queues at the plane.

Cabin crew couldn’t be less interested. Cabin manager was the most arrogant and the rudest I’ve encountered in many years.

Good but both flights were delayed by nearly one hour making boarding tedious. We had to wait with no information

The worst flight ever. Sitting in plane for 4 hours delay and then they change crew. No water or food offered to any passengers including children in that time. Only 2 toilets out of 3 operating for flight with 200 passengers. Only enough food available for about 7 rows of seats depending where you sat you might be lucky. Cabin crew very unfriendly.

Unnecessarily delayed and remarkably inefficient boarding contributed to a significantly delayed departure. Seats/legroom astonishingly uncomfortable even by Ryanair standards (minimal legroom plus reinforced plastic seat backs ensure you get punched hard in the knees every time the person in front moves, and as a 6-foot passenger I had nowhere else to put my legs. Upon late arrival at the gate in Luton we were kept waiting another 20 minutes before being allowed off the plane. Both Easyjet and Wizzair are currently a better bet.

Awful as usual the air stewardess loved her own voice and would not stop talking on coms for 2hrs please please please shut up I can’t hear my headphones and don’t want to buy juty free

Big delay on run way not much explanation why, missed a important meeting in Dublin, maybe if they did nt persist measuring everyone bag over 2 cm we would have got off on time.

The lady at the boarding gate was so rude. She was challenging people being in priority and looking them up and down as if they weren’t dressed for first class. This was Ryan air priority. We all sit in the same seats. She loudly called out to embarrass a man who she believed had cheated and got in the priority line. He had a valid priority ticket and even worked for Ryanair. Also challenging visas insisting people download them until they proved on the government website it wasn’t required to print. The Ryanair employee who was challenged said she is always like this. She also pulled people from regular boarding as they were fashionably dressed and upgraded them to priority and changed their seats. That was comical. I think she felt she should be working for Emirates first class, although they would t have stood for her rude behaviour

On time boarding, on time departure and early arrival. As it should be. Yes, the comfort and benefits are very poor, but therefore the ticket is 6 times cheaper than with a flag carrier. So I am not complaining about it. You get what you pay for.

The punctuality of f the flight was super: we left on time and arrived about 20 minutes early - and the cabin crew were both friendly and efficient. The only downside was that Ryanair appears to have resumes its old obsession with sizing cabin bags again after a long and welcome absence.
