Very quick flight, efficient boarding, and clear and thorough instructions and attention from staff.

Amazing, not too crowded, great temp and the meal was good

The crew was good. The flight was not overly crowded so we had some additional space.

First time flying airline. Great experience. Clean plane, comfortable seating, great service.

They lost my bag so that is unfortunate.. still waiting for it

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 😊

Pretty bad. No welcome drink (the Lufthansa signature drink they advertised but did not serve). No 2 round of beverages. No coffee to end your meal. No snack before landing on an overseas flight. Mediocre everything and unattentive staff. Munich and Frankfurt as connecting flight airports are terribly big (20 min walk for transfer!) and confusing. Will not fly again.

No food available for purchase on a 2:30h flight around lunchtime… Lufthansa hand luggage policy and behaviour makes you feel you’re on Ryanair but paid three times as much

My premium economy experience did not live up to my minimum expectations. I've taken this flight twice in the last three weeks, and each experience was the same. The premium economy seat was worn and extremely difficult to recline. It took two people to return it to its takeoff and landing position. The food was OK, but for the premium that a premium economy seat cost, I expect a satisfying meal. Years ago, I looked forward to the experience of flying transatlantic on Lufthansa (I especially enjoy the hot towel before the meal), but this is not been my experience recently. I'm not going to use Lufthansa again.

If was mostly my own fault. I booked and paid for a window seat. That was a mistake for a long flight. It was hard to get up and use the bathroom. The entertainment system seemed primitive for a modern aircraft.

It was a safe and smooth flight. Members of the crew at the second level, business could have been more polite and engaging.

Our seats were not together - one on upstairs business class, the other nicer downstairs business class. Terrible!! A very nice agent worked hard with other passengers & got us upstairs together. Not ideal experience. Check in agent should have caught that! Asked about upgrade to first class for additional $2500 each. Refused upgrade saying we upgraded once already. We booked on business class to begin with so we’re NOT happy!!

Everything was good except the seats we originally picked we did not get when we paid for extra leg room. Had to wait till last minute to get assigned our seats which was nerve racking

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.
