Everything was great!! I had no problems!! I would fly Aer Lingus again! 🥰

From Rome to Dublin if you want any refreshments you have to pay for them, Not used to this as we typically get soft drinks and a little snack on a 3hour flight in the US.

Boarding was fine, difficult to understand the guy over the speaker though so we were unsure when exactly to board until they updated the monitor by the gate. Flight itself was fine, nice flight attendants, seats were comfortable enough, good selection of entertainment on the screens. Other airlines at a similar price point have included wifi though, at a minimum messaging, for free, so that was a little disappointing to not have that. But otherwise fine. Food was pretty decent, nice hot meal, good drink selection, nice snacks. Bathrooms were ok, could've been cleaned a little more often, but they were never bad.

Vegetarian food option was very poor. Effectively, overcooked rice ("risotto"). Zero protein which is always disappointing with no vegetables and poorly seasoned. Basically had lots of carbs on 6-hour flight. Not acceptable for business class in 2026. Flight was otherwise very good.

Small plane. Tight seating . What can one say except that it was fast!

Flight crew was very cold and stood around a lot talking to each other.

I sat in the first row behind first class. There was plenty of legroom. The entertainment was great. I saw two excellent movies and one episode of a sitcom. Also enjoyed the flight tracker.

On time, only a little turbulence, very competent and caring attendants. Clear information.

The flights are literally always delayed arriving, boarding and taking off so they are always late for the connection. I planned ahead so I was okay but many others aren't. The food was terrible. The staff was very pleasant. I appreciate boarding back to front.

On a four hour delayed flight now on seats back end of the plane instead front-

Good. Rxception is the Entertainment - movies and TV shows all out of date…

The crew was attentive and personable. The plane was clean and the seats comfortable. It was an excellent trip!

We paid for saga class, which is the business class for international. My seat was broken and did not recline and my monitor for in-flight entertainment was broken.

The flight itself was fine, even with a one-hour delay leaving on the Reykjavik tarmac (the lost time was made up during flight). Our experience at the Reykjavik airport on arrival was terrible due mostly to the one hour it took for passport control. Only two stations were open for our category, and the room was full with a huge crowd.

I liked the crew but not the uncomfortable seats and lack of movie and tv selection.

Awful. The Iceland airport was a complete mess. Boarding was a chaotic, the seats were awful, there was a group of rowdy 20 something men in our row hooting and hollering, ordering alcoholic drink after drink. Yelling and laughing at the top of their lungs and the crew just went along with it. Passengers complained to the men, asking if they could keep it down (it was a night time flight so people wanted to sleep). They never listened crew continued to laugh with them, flirt with them and serve them more drinks. No free food or snacks, seats were horribly uncomfortable. Worst flight I've had in a long time

Repurchased food and it was moldy and expensive. But I figured it was bad luck so I purchased a cup-o-noodles, halfway through them we hit turbulence and the flight attendant was passing with the garbage, it would have been two seconds to grab it, but he was snarky grabbed someone else’s plastic cups and went to buckle up… I used the puke bags to secure the soup before it became an accessory. When he finally came around he gave me a face like a petulant child as I handed him the soup neatly wrapped in the paper then plastic bag. I watched a movie in silence as the rental or headphones was ridiculous at 4€ for those .10€ cheap plastic toys. No English subtitles on an American movie… crazy. I disliked the whinny little tourist trap and now I hope that it sinks into the ocean or erupts in a catastrophic eruption for their beloved “I live on an active volcano” pride.

At least one soda free, felt like I was nickeled to death.

Pleasant, attentive flight attendants, but they’ve got to upgrade their seats to be a true “business class” carrier.

Friendly flight crew. Airplane (757) configured as a domestic flight (no lie-flat seats) & no advanced meal selection.
