Cabin crew was one of the worst in memory. Poor in delivering service - in some cases skipping it altogether. Someone in baggage handling managed to steal my electronic bag tracker from Apple.

Cabin crew was one of the worst in memory. Poor in delivering service - in some cases skipping it altogether. Someone in baggage handling managed to steal my electronic bag tracker from Apple.

I buy ticket from you and when I go to the airport aer Lingus they tell me you need travel visa for Ireland for one hour travel so when I buy tickets there no requirement I need transit, visa or not so when I try to cancel my ticket or change my ticket, you guys say there is no refund so you u guys take all my money which is very disappointed

The aircraft was clean and relatively comfortable- for an aircraft seat. The entertainment was good. The food was terrible, especially the “breakfast “ which was a cereal bar, and just not good. The crew were amazing, professional and no complaints there. The food was so bad, I know for my return, it will be inedible.

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.

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!

The flight was delayed leaving Philadelphia due to “catering” and consequently arrived in Dublin some 75 minutes later than scheduled. Consequently this caused me to miss my connecting flight to Glasgow and I had to spend the night in Dublin.
