8.0 Very good
The biking process was confusing and I was called for a seat assignment from I number I repeatedly though was spam, but the flight itself was great
A
4.0 Mediocre
The same as I stated prior. We incurred extra costs that should be reimbursed, given we were not communicated with about schedule changes.
A
4.0 Mediocre
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.

4.0 Mediocre
My experience with Aer Lingus was not too good. First, because of the last minute delayed flight from Amsterdam to Dublin we almost missed our flight from Dublin to Philadelphia. Secondly, the flight from Dublin to Philadelphia had very uncomfortable seats especially it was a very long flight. My buttocks were constantly in pain for sitting on these seats for this long. Lastly, the service in the plane was also slow. I asked for a second cup of water and the hostess told me he'll be right back with that where it took him over an hour to come back with water. It was warm in the plane and I was very thirsty. Overall this airline needs much improvement in their services.

No leg room. Warm beer and soda

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

2.0 Poor
This flight left about 45 minutes late, and arrived about 45 minutes late, which was enough to make us miss our next flight and trap us in Dublin for 24 hours!!

8.0 Very good
A complimentary cup of water would have been appreciated

8.0 Very good
I think the extra charges for seating with no added advantage and the added charges for baggage are excessive compared to other airlines.
N
8.0 Very good
I had zero issues with the flight. I did have issues with the staff at the airport. We missed out flight due to a delay with another airline. Talking to the staff and trying to get a new flight arranged was challenging. One guy was able to try to help us and got us on a new flight, but other staff was dismissive and clearly let us know it wasn’t their problem. All I kept thinking was… this is why air lingus has such a poor customer service reputation. I will be avoiding this airline in the future.
