Short flight so not much to rate. Surprised I had to pay for a soda.

Short flight so not much to rate. Surprised I had to pay for a soda.

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

Very good need to offer better choice of food for business

They should. Heck planes more often not when they are suppose to be leaving causing delays

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Great hospitality and service! Seats could always be cushioned better.

Excellent long haul experience really enjoyed using Dublin pre-immigration

Due to long security check and no last call announcements from Gate staff, my family and 12 other passengers missed the flight.

Perfect timing, perfect departure, lovely crew on the ground and in the air.

Good flight. Take off a little late but make up the time

Everything’s went straight forward, no issues, good service and friendly crew

Left on time and arrived on time both ways, thank you

Ryanair is the worst airline in Europe and easily one of the worst in the planet

The flight was 45 mins delayed but the crew provided water and necessities like tissues

Cheap flights as you expect with Ryanair. I would take cheaper flights over entertainment and comfort for short haul travel. Main issue is usually delays at airports. In this case we landed roughly 2hr30 later than planned due to earlier delays with the plane. Not the worst I imagine

While this flight from Dublin to Venice boarded on time, its departure was delayed by about an hour because, apparently, there were no demonstration kits on board, and we couldn't depart until the safety demonstration was completed. We were informed that we were in danger of losing our delayed slot if Ryanair engineering didn't provide the kits 'soon', which would have resulted in an additional two-hour delay. Thankfully, we didn't incur that additional delay. It's not clear where the source of this problem lies but it needs to be addressed to ensure it does not recur for other flights in the future.

We each paid for 10kg checked in luggage. Flying out there were no issues sharing one case (20kg). Not so coming back. Additional £48 charge and unable to provide an explanation of why it was ok on one journey but not the other, or indeed what material difference it makes between 2x10kg cases vs 1x20kg case. Scam, and appalling from Ryanair.

- OK plane. Basic accommodations. OK food. The digital window shade wasn't working.

- OK plane. Basic accommodations. OK food. The digital window shade wasn't working. - Expect to be woken up more than an hour before landing when they start dinging the bell and making announcements and turning on all cabin lights to serve a snack. I would prefer they remain quiet and only serve people who want to wake up.

Great!!! The first flight was a little painful because the chair wasn’t reclining and my back was destroyed by the time I got in London. But the second flight was perfect!! Super comfortable, the food was amazing, the crew super polite and helpful. Overall, I had a good experience

Better food and more space in the seats. Also when doing the web check in both times I was going in to your site the minute you open it and there is not really many seats to choose only to buy!!!

It was ok, not as good as it used to be. The Heathrow connection was a disaster - complete anarchy, unknowledgable and skimpy assistance and signage. Gate crew at next flight was great, held the flight while my wife struggled through security.

It was great! The seats were comfortable, and they fed me during the transatlantic flight, something which I have been missing out on for the past 3 years as I travel to and from school.

The seats were uncomfortable. It was an old plane. The crew could have been more hospitable.

This flight was cancelled at the last minute. We were rebooked on another flight but a day later. We lost a day of our vacation and paid for a night in a hotel we couldn’t use. The flights we were rebooked on (both American) messed up our seating on both flights-we didn’t get the seats we had paid for. All in all, a terrible experience.

I declined a wheelchair in Vienna as I was told it was a short walk. However, though I "boarded" the bus first, I was at the back when we got to the plane. There were steps up to the plane and no-one helped except the stewardess as I was near the top of the stairs. She found a better seat for me also.

Horrible connection in Heathrow on flight to destination. Flight missed due to delay on incoming flight. They did rebook us, and then that flight was delayed 2 hours. They don’t post gate info until 45 minutes to departure time which can cut it close if you have to take a tram to your terminal gate area. Then our return flight was completely cancelled. They notified us at 4:30AM. They rebooked us on a different airline and a different fare class. We were completely screwed. Travel day ended up being 30 hours. I will never fly them again.
