Disembarkation at Dublin Airport especially arrival at the terminal building was very difficult, protracted passageways that were dirty

Everything is good, but my luggage was damaged. How are you guys gonna pay for my luggage?

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.

Boarding was chaotic and unhelpful for a mobility assist passenger. Flight was fine. No food or drink offered for a three hour flight other than water.

The second leg of the trip was ok. I had a premium economy ticket and that was not touched by the airline.

Proximity of the the gate to the lounge could have been better but overall a nice experience. The lounge was exceptional. Getting from the Schengen side to the international side was also pain free. Boarding the plane, service on board , disembarking at Heathrow and quick delivery of bags all made for a good overall experience.

Again another extremely chaotic boarding for the flight. Could have easily opened up more automated gates and the staff could have proactively managed the queues as they're forming rather than sitting behind the counter, waiting for the boarding to start.

My flight to Frankfurt was a very pleasant experience. The food was good, but what really stood out was the cabin crew, who were exceptionally friendly, attentive, and professional. The service was excellent—honestly, better than on some much more expensive flights I’ve taken. A wonderful experience overall!

The flight from FRA to SFO was uncomfortable. The crew allowed people to change seats after boarding finished, but then made some people move back to their seats but not others, which resulted in my wife and I having to sit in two middle seats for an 11 hour flight. The entertainment system was not working well throughout the flight, and stopped working completely around hour 8.

Review what was entered already in the same booking. Not sure we will use Arrant Grant, given what happened!

Great service food was very good and overall experience was great !!

When I fl with Bulgarian air, I am greeted with a bottle of water and a packaged cleaning wipe. There is a hot sandwich and a drink offered afterwards. Towards the end of the flight, there is a piece of chocolate and per request an additional water bottle. For the price that Lufthansa charges per ticket, it is embarassing that other airlines can offer better customer service quality on board. Also, some of the Lufthansa flight attendants act very entitled instead of being customer focused. Regularly the mobile lift for diabled passengers is missing... Every time when I fly with my 89 year old mother, she is being questioned multiple times whether it is okay to use the stairs ( she walks with two canes). Most of the times when we arrive in Frankfurt, the mobile lift is missing and she is urged to use the staircase. When I refuse to allow this, the flightattendants look at me scornfully. This is not WW2 where disabled people should be treated as second hand people... Then we all have to wait another 30 to 40 minutes on the airplane, while waiting for the mobile lift to arrrive. Does Lufthansa have enough money to waste on an airplane waiting for (on the average) 30 min for the mobile lift to come? I fly frequently and have experience mostly with Delta, United, Southwest and other American Airlines. Lufthansa needs to pick up their game on board, if they want to stay competitive and in the game...

Overall excellent service and Frankfurt Airport was very efficient and clean
