Awful customer service. What you are told 100% depends on who you talk to.

I love flying with them, the long-haul was fantastic. The short flight from Dublin --> Switzerland was horrible though. Most narrow seats I ever had, first and only time in my life I couldn't even close the seatbelt in seat 1A which was very embarrassing so I had to sit in the middle, because that seatbeld was 20cm longer. No idea why seat 1A would have a much shorter belt, it's just ridicilous. Also I hate the fixed seats, way too narrow.

Food was mediocre, but as expected in economy class on an airline. Wrap was ice cold , my son’s served by a steward on the next aisle was warm . As expected, but at least heat the food up a bit. No frills, but it’s economy. Excellent free WiFi was a bonus

I flew Aer Lingus Business class for the first time. Having flown economy a few times, I was familiar with the airline, and happy enough with economy. I’ve certainly been in nicer economy airlines before, but Aer Lingus is usually very reasonable, and I find the staff to be kind and have an Irish sense of humor and accommodation. The business experience was good, in that you got superior service to the back, lay down seats, better food and drinks, and more attentive service. However, the plane was a bit older, the WiFi was slow(not Starlink) and the pods were too close to one another for privacy, or function. When the Oder lady to the left of me fell asleep(fully reclined) there was no way for me to escape without having to wake her and put her seat all the way up. That lead to me being stuck with luggage I couldn’t put away in a cramped(for business) space, and no way to use the restroom for almost the whole 8 1/2 hour trip. I ended up trying to sleep with a large backpack blocking my feet. The food was good for plane food, but not great. The drinks were great, shame I couldn’t have had more, but I’d have peed myself. I love a window, but next time maybe an isle seat. Overall, the experience was good, not great, but an expensive good experience during which I got zero sleep. I’d do it again, but it’d have to be a deal.

The direct flight was a superb idea; please continue. The seats were less than comfortable for such a long flight.

We missed that flight, and I am hoping that we will got the refund. It was very confusing to figure out about Aer Lingus operated by American Airlines. Then we bought another more expensive ticket to travel.

The check in and boarding process was smooth, and the flight was fine.

The free WiFi was great so I could stream movies during the flight. I would like to have movies available instead of on my device. Thanks!

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

Flight was ontime, clean, staff was friendly - there was turbulence but can’t avoid that (it’s a flight 😉)! The staff were attentive but would be nice if Aerlingus didn’t charge for coffee ☺️ but overall I enjoyed my flight experience and will travel with them again (Ireland’s Four star airline
