Like getting a bus. No great luxury but will get you there

Got us to destination alive, albeit a bit late. Luggage was left behind. No live tracking app available (available on some other airlines). Supposedly going to be delivered in next couple of days.

Flight takeoff was delayed an hour, but arrival time was not updated at the same time as departure time, so those picking me up at the other end were not alerted to the change in my arrival.

I had zero issues with the flight. I did have issues with the staff at the airport. We missed out flight due to a delay with another airline. Talking to the staff and trying to get a new flight arranged was challenging. One guy was able to try to help us and got us on a new flight, but other staff was dismissive and clearly let us know it wasn’t their problem. All I kept thinking was… this is why air lingus has such a poor customer service reputation. I will be avoiding this airline in the future.

I liked that I went thru customs in Dublin instead of having to do that in LA.

Baggage fees are deceptive! When I booked this flight, I purchased two tickets and had indicated that I wanted one checked bag. That increased the ticket price by about $100 PER TICKET!. When we went to check in, I was told that I could only check ONE bag, even though I had purchased TWO tickets. I had to pay an additional $50 each way for my wife’s bag. In my opinion, I paid twice for her bag.

Delays resulting in missed connecting flight. Attendant failed to arrange special assistance as promised to get us on connecting flight. Robyn was the particular attendant.

This was the most expensive economy flight per minute of flight time ever. But the quality was lacking. Extremely Aer Lingus rude staff at LHR said that the flight from London to Dublin (Ireland) was “NOT international.” Horrified at the colonial and imperial perspective. Seats were dirty with trash in seat pockets. Airline doesn’t clean or care about hygiene and safety.

The ease of boarding was good. I wish they had something to eat on the plane.

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

Great flight just took some time to board even when lining up early for the flight, even taking off took longer then expected.

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.

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

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

We were diverted to warsaw and there was zero information. We were just forced to disembark and off we go good luck the reat of the way. We all had to go our ways to find a way home!!!! Horrible horrible and it cost us alot of money to get a hotel and trains 4:30 pm next day.

Blood contaminated tissue was stuffed to the back of the seat in front of us.

My flight was delayed 1 hour. My Mood was not great

This time round it was very good, flight delayed by 30mins but capitan put his toe to the floor and made some time up!!

Ryanair is always shite. Slowest boarding possible in the most uncomfortable way. It’s like they are are tad sadistic.

Waiting area not big enough for all the passengers, no airport lounge.

People were nice. Seats are so cramped my knees had to be pressed into the seat in front of me.

Dreadfully long wait for bags at Dublin coming off an already late flight.

Flight was delayed and there was boarding pass and flight information errors resulting in confusion and stress

Aer Lingus was the actual airline so they handled everything professionally.

Excellent service smooth flight f or the most part food was right now.I'm expectedly good.

The flight was delayed, and delayed some more. But there was more room on this plane than the one that flew oversees! There was no food or entertainment, but that’s ok, it’s a short flight

Was delayed for checks after evidence of bird strike, good call

The plane was delayed. That was only downside to flight. Crew was very nice

It was truly amazing. I will do it again! Excellent!
