I was pleasantly surprised. I've never flown this airline and the seats were comfy, I couldn't select my seat but luckily got aisle and was able to comfortably sleep the whole trip except when they came around with an in flight free meal, drinks then snack at the end. I'd fly with Aer Lingus again. The only annoying thing is you had to pay for WiFi for different hours of usage but luckily I didn't need it

This was a great flight. I love the way they had general boarding board from the back first by seat row and in general the flight was very comfortable. The seats were actually comfy, and the food served was surprisingly good.

A seat was broken There was a delay of 45min A checked bag was missing in Boston

The service was some of the worst I have experienced on an international flight. The service was rude, the quality of the food was very low. The speed of service was insanely quick. You couldn’t finish your pretzels before the meal came before the coffee came before trash collection came. Then they never came back for 5 hours. They rushed everything so they could get it over with.

A special shout-out to one of the check-in staff at DUB yesterday noon. We had to use the "Closing Flights" counter and we met, hands down, the most efficient person - able to resolve several issues in the matter of minutes, while remaining polite and calming everyone down. Great job, Aer Lingus!

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.

Terrible. So upset either way this flight. We scrambled to make it as it was delayed an hour.

Great customer service. Frequent updates from the pilot. Smooth flight. Good entertainment. Meal service.
