Wheelchair assistance didn't turn up on time. We had to walk to baggage reclaim and to taxi.

Fast and sensible boarding was absolutely amazing. But extortionate wifi and seats that barely moved, making me unable to sleep, didn't do a lot of favors.

No food service. A sandwich at this hour would have been good. My 1st time on AL so didn't look into pre board purchase options.

Late. Taking off, landing, deplaning. Missed our connection on AerLingus to NYC. Computers down from cyber attack. Put us up for the night. Lost our luggage. Everyone was nice. But it was an awful day.

I liked the front row seats. A lot of leg room. The check-in window needs to be longer

The actual flight experience was great. The handling of my luggage was terrible. First, I had to check in at the airport and wasn’t able to check in online because they booked me with a partner carrier in the U.S. that was incredibly inconvenient. I was also told that I would have to check in again with the partner airline in the U.S., also incredibly inconvenient at a large airport. Second, when I was at the counter, they did not tell me my carryon was too big. I only found that out when I tried to board the plane. I don’t know that it actually was too big though. It’s a standard sized carry on that I’ve never had issue with on any planes before. They assured me my bag would be checked all the way to my final destination. Due to flight from Paris to Dublin being delayed, I was rebooked on a different transatlantic flight to the U.S., which resulted in a different connecting flight to my final destination. My luggage was rerouted and I was assured it would be at my final destination. When I got to Newark, I received multiple phone calls alerting me that my bag was across the airport at a different terminal and that I needed to go pick it up near the baggage carousels. In the Newark airport, every terminal has its own security checkpoint. Leaving any terminal and entering another one requires a security check. At this point, I had to go through security in Paris, then again for US customs and pre-clearance at Dublin, then a third time when I had to change terminals at Newark for my connecting flight home. It was at this point I received the call that I needed to retrieve my bag from literally the opposite end of the airport and go through security A FOURTH TIME. These was no notification that I needed to do this before I went to the gate for my final flight. It took me an hour to go do all this, after I had already been traveling for 19 hours while sick and should have been home already were it not for the delay of my original flight. I retrieved the bag. My carryon became a carryon again and fit just fine on the last plane, by the way. I would also like to mention that my TSA flight information was not included on my ticket, so once again, I had to go to the airline counter to get my ticket corrected and reprinted before I could go through security and try to save myself time. Finally, I have celiac disease and prefer not to eat meat. There was literally no food I could eat on the seven and a half hour flight across the Atlantic. When the flight attendant woke me up for dinner (I would have preferred to sleep), I asked if there were any gluten free options. I was told the only option was chicken. I begrudgingly accepted because it was the only option, hoping anything else in the meal could be eaten. There was plain rice and a few green beans. The side dish was teriyaki vegetables containing gluten. There was a piece of bread, containing gluten. There was a custard, containing gluten. I could eat literally nothing except the very small amount of rice and green beans. When the same flight attendant came around again, while I was sleeping, a sandwich was placed in front of me, again food I could not eat. And this was after I got to the flight to find that my newly assigned seat on my transatlantic flight had been given to someone else! It’s like nobody communicates over there. This airline has the worst logistics of any airline I have ever been on, and I travel frequently. Dear Aer Lingus, DO BETTER.

Conveyer belt at the check in area stopped working and check in process was significantly slowed down.

A caveat, we flew during the ransomware attack that hacked the boarding and luggage tracking systems. I wouldn't ever be angry at the employees for that, but I WOULD be (and am) angry that communication was incredibly poor, that we got few live updates, and that the employees seemed uninformed and ill-equipped to handle the situation. Clear, honest, open communication and instructions would have benefited the situation. Unfortunately, there were literally no gate agents to talk to, no airport employees to direct people, and no clear signage (the app pretty much said "we don't know what gate your flight is."). Beyond this nightmare, the security was the usual dehumanizing circus of "Security Theater" which is... as we all know... only for show and completely useless. All three airports on this journey dropped the ball so hard. The flight industry can do so much better. Aer Lingus can do so much better.

I was pleasantly surprised and enjoyed the services of the airline since flying is not my favorite thing. My goal was to be with my brother's family in Manchester after his death. All staff was helpful, the food appreciated since I selected an overnight flight. Every aspect of the experience was comforting. I plan to return to Manchester in order to attend my brother's funeral in October and hope that I am able to find a reasonable priced flight. Thank you

The worst Terrible Late for connecting flights. Made flight without luggage! I am still waiting for my luggage to be returned! I paid premium for this flight. My luggage should have been flown to Hartford instead they keep telling me it was put on a jet blue flight and is in New York! I flew Hartford to avoid New Yofk! The flight over was also unpleasant. We were stuck in a bus at Edinburgh airport for 30 minutes then our luggage again could not be found! Very poor service. Very disappointed . I need my luggage to be returned.

Take off was great but landing is always with a bump.

Staff were very professional. Much better than the outgoing flight from Dublin. Seat cushions were practically non existent. Making for a very uncomfortable flight.

Flight was delayed by 1 hour 45 minutes. Aircraft was cramped, dirty and uncomfortable. Boarding staff more interested in charging you for oversize baggage than getting you on board. Overall not a pleasant experience.

They were extremely unprofessional and unhelpful at check in. They did not understand laws related to Spanish residents flying with family It was very discriminatory the way we were treated.

A delay of almost 3 hours. It was evident that the staff wanted us to board urgently, to the point of rudeness, to avoid paying compensation

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

On time arrival but the aircraft had seen better days and needed a deep clean.

It was appalling, full of young people who were drunk and disobeying instructions to sit down. Crew did nothing to enforce. There was a Ryanair pilot sitting in the aisle opposite me who talked through out the safety briefing so loudly I couldn’t hear. Whole thing felt unsafe

Delayed for 2 hours lack of communication no refreshments as promised and the drinks on board were not as ordered and refused to refund

Flight was fine, crew were good, cabin director spoke far too much; disembarking at Dublin Airport and entry into the terminal building was just dreadful, like entering the back door of a neglected factory building. What an awful impression it must give to first time visitors to Ireland.
