No snacks, drinks or coffee. No entertainment, not comfortable seats

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!

Customer service was excellent! The app was terrible, tried several times to check in without success! But the young lady that checked us in was absolutely terrific and helpful.

Horrible. I had to wait in Dublin for 4 hours for the next connecting flight which took my to London and than i had to wait 3 hours for the flight to Dusseldorf

Was not aware that Aer Lingus was like the cut-rate services in the states, with no food or beverage (other then 3.50 Euro coffee) and no screens for entertainment. Was a great flight, but not much in the way of services.

I didn’t realize Aer Lingus was a “nickel and dime” kind of airline where you had to separately buy all the amenities you wanted. The push to purchase duty-free beauty products was off-putting. And our row had the least amount of leg room I’ve ever dealt with on a flight.

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Very efficient and excellent service. Nice amenities and beautiful plane. Elevated meals. Boarding could have been more organized. We missed our connecting flight due to EU entry but Lufthansa was extremely quick to rebook us.

Aircraft had fairly roomy seats on economy. Food was good (beef dinner).

Broken seat did not recline fully, broken footrest, no air vents, no electricity for charging devices, outlets for headphones or isb did not work. Rude crew. Horrible experience. Would never fly Lufthansa again

They did not serve my special meal request after departure of airplane

It was a very smooth and on time flight experience. The crew was really friendly and polite. We were well informed about the flight, etc.

Lufthansa was horrible for disabled folks. My wife had hell of a time making it to the flight in Frankfurt. The airlines is not at all caring to the disabled. If that were in USA I would have sued the airline for not meeting the disability Act clause. No way we are going to go in Lufthansa again. Hari S Doss

The Discover flight from TPA to FRA was exceptionally unprofessional and incompetent in organization. First the entertainment system was completely nonfunctional for the entire plane and no competent IT support to fix. Than they could not serve any coffee or tea because they ran out of water - reflecting the exceptionally incompetent management at Discovery and most embarrassing for Lufthansa and a German airline, more like a third world country. The food was mediocre at best and minimalistic for Discover, particularly with the much higher standards at Lufthansa.

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

Staff was rude in business class. Luggage was damaged and nothing was done about it airlines.
