Aircrew was very very supportive helpful funny and accommodating. The flight itself was very smooth the pilot was very informative and we were very comfortable with all of the accommodations and concessions that were given. Really liked the Hub in Dublin that allowed us to do US Customs before getting back into the US to eliminate extra hassle and Rush their staff was always accommodating and very informative with signage every step of the way

This was the worst experience I've ever had with an airline. For the first wing of our international flight, we were stood in a boarding line for an hour, which was taxing because I am disabled, and then my husband and I were split up, and I was placed at the front of the plane. A flight attendant took my bag from me, which contained much needed medicine, and placed it in the overhead compartment. Because I am disabled, I needed my medicine accessible, and without my husband to reach it for me, I was stranded. My husband had previously communicated this at the gate, and they moved his seat closer but still several rows away from me, and in a center seat where he couldn't easily get up and assist me. We would have even paid extra to select our seats and to sit together, but there was no option for this. Luckily another passenger gave up her seat so that I could be with my husband for assistance, but the flight was deeply uncomfortable due to the delay in my medication and the overall conditions of the plane. For the second wing of our flight, we had the same lengthy boarding line, and somehow my husband and I ended up in adjoining center seats, which were exceptionally uncomfortable. Additionally, my husband is 6'5'' and we were both placed in broken seats - mine was stuck in a reclined position, and my husbands was stuck in a cramped upright position, with our shared armrest being broken as well. Much of the front of the plane was completely empty, and another passenger had been moved up on request, but when I requested that we be moved up to empty seats, the flight attendant I spoke with declined, leaving us in broken seats and extreme physical discomfort for the duration of a transatlantic flight. Other services throughout the flight were spotty, including simple food and beverage service and trash pickup. Flight attendants routinely forgot my husband and I and only offered items to folks on the aisle seats, and when I requested water on one occasion (to take with my medicine) I was ignored. At the end of our flight, I was barked at by a flight attendant to put my seat back up - enraging because I couldn't as my chair was broken, and because my earlier request for an unbroken seat was ignored! If my seat needed to be up for safety reasons, then Aer Lingus' staff placed me at risk by refusing to move me to a seat where this was possible. It took us several days to recover from the physical strain of this trip - not at all what we had hoped, coming back from our honeymoon. Overall, this was a deeply unpleasant experience and my husband and I will be avoiding Aer Lingus as well as encouraging all of our friends and family to avoid Aer Lingus as well

It was poor overall. They cancelled our flight and changed it without notifying us. So we incurred extra costs by having to book a hotel for our layover. They say it's Kayak/Underpricer's responsibility to reimburse us. But Kayak/Underpricer have said it's Aer Lingus' responsibility because they are the ones with our 'booking information.' I find this situation confusing and unacceptable.

Staff was generally friendly and helpful. Attendants collecting trash were somewhat inattentive though.

It was my first transatlantic flight with Aer Lingus. Very enjoyable. Thank you for making international travel enjoyable again.

Everything went well. I made my connection which is always a concern.

The flight was delayed by about an hour, but the staff and signs at the airport never actually said it was delayed. At the expected boarding time, we were told we would be boarding in about 10 minutes, then 20 minutes passed, and were told again that we would board in about 10 minutes. That happened multiple times, such that "10 minutes" turned into an hour.

Both flights were delayed due to maintenance issues. Because they where late boarding all four of our bags where left behind on our last connecting flight.

Staff are so nice and friendly, plane was very clean and plenty of leg room

It has nothing to do with Aer Lingus and everything to do with Frankfurt airport. There eere no visual displays of the flight destination at the gate. They kept changing our gate with semi audible public announcements and eventually I was at the wrong gate and my flight departed from the other gate.

It was ok no problem on flight after the ordeal with passport control. Long line and nasty officers not very helpful.

roomiest flight in economy I've taken in years. Excellent experience!

I was disappointed that paying nearly $5000 more for business class for two didn’t really get me any more than a larger seat which as the last row in cabin reclined only mildly and the foot supports were of minimal help and left no room under seat ahead for carton bag. Second, our checked luggage was lost and took us two long days and we’ll after midnight each of them and multiple calls and 30 euro trip to airport in person to finally get them. Would you do this again?

I bought premium economy tickets with a fully flexible fare, and made seats selection for me and my son: window and aisle. After checking in online, Lufthansa cancelled the seat assignment without informing me. As a result, my son and I were assigned mid-center row seats, in different rows. This ruined the trip.

That was the last time I booked Kayak. The connecting flight got canceled and the trouble shooting terrible. Next times, I will book the airlines directly. Good bye

I want to highlight the crew members and their excellent work and professionalism. They work hard to make a long trip the most comfortable as possible, the food and drinks they offer are pretty good. And they are always asking if you need something else. I have had experiences with other airlines where you have to basically beg for a bottle of water. This is not the case. Highly recommended!!!

Way too crampled. Charge more and put in less seats.

I was first assigned a seat that could not recline fully and was at the back of the craft. I was not able to select another seat during check-in even when opting to pay for selecting a different seat. I had to contact the airline and spent 25min with a chatbot and was then transferred to an agent who was very helpful and could change my seat (free of charge). The entire process took me one hour. If I happened to not have that hour available this would have been a problem. And that was only to check in. The next problem is that the airport lounge I had access to is located landside. How strange. So it means that you need to allow time for security check and passport control and boarding time when leaving the lounge, which makes it almost pointless having lounge access unless you have a very long layover or arrive 5 hours before the flight. Inflight service was okay. But not up to par with the likes of QA, SQ or CX, even though the price is the same or even more. It was much better than the domestic flight where Lufthansa is actually a low-cost airline with legacy airline prices.

One of the best airliner in the world But airport was very poor

Overall excellent service and Frankfurt Airport was very efficient and clean
