Flight was on time, staff are friendly and helpful onboard.

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

First of all we couldn’t check in online, then we learn at the airport we were on stand by for KLM’s mistake of overbooking. The seats were not comfy at all. Our luggage got lost.

Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

The baggage drop-off in Stuttgart is bad: after online check-in you cannot use the automated baggage drop off as indicated on the website. You can use the terminals but have to cue to 1 of three open and slowly working counters to drop the bags. took about 45 minutes wait time.

Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

My flight was delayed by 6 hours then I missed BOTH of my connecting flights, I then had to stay in the AIRPORT at JFK because soooooo many people also suffered from missing flights and there was no hotels available. I would like to be compensated for this experience! I had to stay in the airport for over 16 hours!

The staff was amazing, so friendly and responsive. Check in was tedious as the online service was not available and the desk understaffed. It took a full hour in line to check in. The seats, in economy, where quite spacious until the people in front of us reclined their seats which then meant the seat was touching our knees. The inconsiderate people who were seated in a bulkhead kept their seats reclined for 80% of the flight and then got annoyed when we bumped their seats while shifting positions. It was highly unpleasant..

The connection time between the regional flight (from Newcastle) to an international flight (to The States) was too short. To require as second security scan and customs clearance within an hour and 20 mins is not enough time to make the actual connection. We had a final boarding call the minute we walked out of US customs and had to sprint (with two small children) through 20 gates to make it in time before the door closed. The concept is great in theory to clear customs before leaving Europe, but the timing needs to be adjusted. We travel abroad frequently and won’t be using this route again. Thanks.

Canceled my flight couple hours before takeoff. They could not find a decent re-routing and refused to pay for when i subjected alternative with Lufthansa.

Seats a little to soft on the SFO DUB flight

I was not admitted to the flight!!! I need a refund for this

Well, I think we left close to on time. Crew was “eh”.

This is a bit of a rant, but I'll try to keep it civil. The flight was delayed for 2 hours with almost ZERO updates from agents. Just "there's technical issues, we don't know if or when it'll be resolved" once an hour maybe? And the gate signs, and app never updated to show the delay until it was finally resolved. So when I called Aer Lingus to see if I could rebook, I had literally the dumbest conversation with the person on the phone there where he says "It's showing your flight departed at 11:10. So it's already departed!", where I responded, "Well, it's 12:45 and I'm on the phone with you, standing in the airport, staring at the plane. So...I'm not sure what your system is saying, but we aren't in the air right now.". He said "Nothing I can do. Since it doesn't show delayed in my system, you would be charged to reschedule." Once we finally departed 2 hours late, things were going smoothly as I would expect, except in another very strange way. The stewardesses were rolling the cart down the aisle offering drinks and I asked for a water, to which they said "Sure, you can buy a bottle". I'm not sure if this is an Aer Lingus thing. Maybe something I'd expect from Ryan Air, but for a 3 hour international flight, to not have complimentary water available for customers is an absolute first, in 15 years of flying for me. I'm not upset with the plane staff at all. They were very friendly, but Aer Lingus' policies, how they handled the delay, and the unbelievable conversation with the customer service representative, leaves a lot to be desired in those areas. Also, I'm not upset about the delay. Things happen. Technical issues. But this is a place where airlines really need to clearly communicate with their customers. They also changed gates from 12N to 13N and there was no notification on any app, or announcement over the PA. End of rant. I hope they get some feedback on how to improve communication, because otherwise, they were great. And the second leg of my trip was incredibly smooth - no nickle and diming water, no communication issues. Very professional and efficient and even landed early

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.
