Everything was fantastic. My trip was short and sweet. No problems. Just remember. My paid checked in was i belive 2 to 3 lbs overweight. I believe I could have been given a discretionary pass rather than paying or unpacking. Especially as flight was probably half full only. Thank you

Everything was fantastic. My trip was short and sweet. No problems. Just remember. My paid checked in was i belive 2 to 3 lbs overweight. I believe I could have been given a discretionary pass rather than paying or unpacking. Especially as flight was probably half full only. Thank you

I really enjoyed the good hot tea and biscuits. I loved the tartan plaid head-rests on each seat and the fact that there were all different. The crew’s uniforms are very sharp looking, too.

I booked this flight thru Kayak and then had to cancel within 24 hours of booking. They only refunded part of the fare, saying that was the usual practice. I was not pleased.

Everything! Not sure if there's really anything that could make it any better

Very quick trip from Southampton to Edinburgh Arrival a long way from baggage and up 3flights of stairs no lifts or escalators

The folks and flights were fantastic. I unfortunately wasn’t able to order a meal that I could eat (I’m gluten free) because I got my ticket through kayak, but they tried their best to find something to help me get through the long flight and I’ll forever remember their kindness.

Flight takeoff was delayed an hour, but arrival time was not updated at the same time as departure time, so those picking me up at the other end were not alerted to the change in my arrival.

Seats are terribly cramped. I’m only 5’2” and my knees were practically in my face. No room to put a normal size bag under the seat and when the person in front of you reclined their seat your tray table was in your lap. This is the airline’s way of cramming more seats into the plane to make more money. I’ll think twice about taking Aer Lingus again since there are a few other options from Boston to the Emerald Isle.

Couldn’t check In online, message was couldn’t check in until Sunday morning though plane left Saturday night. Checked in okay at airport but caused slot if stress.

It all went very well, except for the ramp coordination upon landing in Boston. That, however, was resolved in fairly short order.

NOTE. Aer Lingus does not accept American Express. I was denied boarding because I could not pay the fee for my oversized bag. I did not have another credit or debit card. Moreover, at CDG, I needed to check my bag at one location, go to another location to check my oversized bag and a THIRD location to pay for my oversized bag. Hence, once I was denied boarding, my bags were already en route to the plane. To retrieve them I needed to go to a FOURTH location in another part of the terminal. Last, Aer Lingus will not reimburse me for any portion of my ticket. I lost $1000 bc Aer Lingus doesn’t accept American Express at the CDG counter even though I paid for my ticket through the Kayak link with Amex. Kayak should remedy this situation if they want to continue to partner with Aer Lingus.

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

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.

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.

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