Incredible airline experience for many reasons. Only improvement, would be to have higher quality food, such as Organic and non-dairy food items. A number of us got sick. Thank you!

Incredible airline experience for many reasons. Only improvement, would be to have higher quality food, such as Organic and non-dairy food items. A number of us got sick. Thank you!

Boarding was a bit disorganized but it was pretty quick!

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.

Absolutely horrible. We missed both of our connecting flights from Frankfort due to the new border control lines. Lufthansa had us running and walking around the airport trying to rebook. They were not prepared to offer us a hotel room for the night, but finally relented when I said I was done with Lufthansa, most were not so lucky. I also put put of the blame in Kayak. You need to update which connecting flights you are offering to allow for more time to deal with the mess that is border control in the EU.

Connecting in Frankfurt was a nightmare! Whoever scheduled our connection in Frankfurt for 90 minutes should be fired! Passport control takes 3 hours, minimum! Avoid Frankfurt airport at all costs! Never again! The airport is 3rd world. The WORST!

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.

Overall excellent service and Frankfurt Airport was very efficient and clean
