I was advertised a free seat selection for a "Smart" fare through BusinessClass.com. I was never able to select a seat. I thus paid extra for a bill of goods I was never provided. would love to speak with a representative of Kayak

The boarding time for this flight was ridiculous, longest in all my time flying. There was a problem with the original plane so it was switched at the last minute. Not a good substitution. We were delayed in departing. The bathrooms for economy were not adequate. The crew were pleasant but not present in the economy section, in an ~ 8hr flight only twice did they come through offering water, easy to get very dehydrated. I had to go and ask every hour for more water. The seats were cramped, and I have no idea what they did to the coffee but it was undrinkable. The food, was disgusting, utterly inedible, I am stunned by the lack of care and quality with the inflight service, very disappointing, I had expected better from Aer Lingus.

We traveled with my 90 year old mother and she was well cared for by everyone from the wheelchair attendant to crew. Greatly appreciated!

Very comfortable flight. Great service, food options, and entertainment options. With Wi-Fi!

On time departure and arrival at LAX - good inflight entertainment - all basic seats on every airline right now begin to feel small after 10 hours!!

I was pleasantly surprised. I've never flown this airline and the seats were comfy, I couldn't select my seat but luckily got aisle and was able to comfortably sleep the whole trip except when they came around with an in flight free meal, drinks then snack at the end. I'd fly with Aer Lingus again. The only annoying thing is you had to pay for WiFi for different hours of usage but luckily I didn't need it

This was a great flight. I love the way they had general boarding board from the back first by seat row and in general the flight was very comfortable. The seats were actually comfy, and the food served was surprisingly good.

A seat was broken There was a delay of 45min A checked bag was missing in Boston

The service was some of the worst I have experienced on an international flight. The service was rude, the quality of the food was very low. The speed of service was insanely quick. You couldn’t finish your pretzels before the meal came before the coffee came before trash collection came. Then they never came back for 5 hours. They rushed everything so they could get it over with.

Dublin airport is big and US Customs and Immigration screening officers are is part of the process there. This eliminates screening upon arrival to US, however should be taken into consideration when playing your transfer. After all, pleasant experience enhanced by draft Guinness and Irish coffee at the buffet area near the gate. We loved boarding by the row, back of the airplane first.

The flight itself was excellent, but getting to the plane was literally an exercise in pain. My wife needs a wheelchair and can only stand/walk for short periods before having extreme pain. We had to take a bus to a loading platform and use a terrible elevator to get up to the plane. Meanwhile the rest of the bus were using the stairs. This meant the people who needed to sit down were stuck standing at the end of the line while everyone else boarded. My wife was in agony.

It was amazing. I sat in First Class as a Saga Premium member, and my service was top notch. It was wonderful. I only recently joined Saga Club since I do travel to Scandinavia often and enjoy flying through Reykjavik on Iceland Air versus other ways of travelling to Europe. This was my first trip sitting in first class, which I honestly wasn’t expecting!

There were no places to sit at the gate. Most people had to sit on the floor or stand waiting for the gate to open and board. We were told we needed passport and the person hardly looked at them. Maybe for 2 seconds. No announcement made asking to board by row or group. On a 5.5 hour flight the crew only came through the cabin 2 times offering water and buy everything else. For the price of the ticket at least offer free soda! The airliner was very comfortable

How can the airline deploy the oldest 757-200 with a broken down entertainment system and no WiFi for a cross Atlantic 7:50 hr torture chamber experience?? My seat 3A couldn’t be reclined. The footrest was flimsy and useless. And there’s no leg support unlike their newer 737-Max which they lavish on intra-Europe routes. Shame!!

We paid for saga class, which is the business class for international. My seat was broken and did not recline and my monitor for in-flight entertainment was broken.

Friendly flight crew. Airplane (757) configured as a domestic flight (no lie-flat seats) & no advanced meal selection.

The most uncomfortable seat i’ve ever had on a flight

Best smelling onboard bathrooms ever. Even after use the whole flight. Biggest overhead bins. Most legroom in economy class. Great Icelandiic music. Really nice staff. Icelandair is awesome! (Don’t fly Air Canada! During the strike they lied about no flights available (I booked this flight myself) and hid the process to get money back on their website by obscuring menu titles, then made it difficult and time consuming to fill out. I’m Canadian. Don’t trust Air Canada!

Boarded with no problems. Sat on the tarmac for an hour before taking off. We were the last ones on our connecting flight. Didn't think we were going to make it. Our flight to Iceland was similarly delayed. When we've flown other airlines, pilots have tried to make up time while in the air. This doesn't seem to be something that Icelandair does. We made all of our flights, but it was stressful and we didn't think it was going to happen based on the time we arrived.

Did not like last minute change to our itinerary that made us spend the night in the airport

We loved our flight attendant (Emma, from Scotland), the meals were perfectly spaced out, and the in-flight entertainment was super generous and delightful.

Why don't they board from the back of the plane to the front. We have to move by all the people and their luggage to get to the seats.

The boarding call announcements versus the Staff announcements versus the digital signage board on the out-going and returning flights WERE NOT IN SYNC. I was sent through check and re-checks 3 times. WHY?

With three empty seats across the aisle from me I politely asked the crew if I could sit in one of those seats. They initially told me I couldn't do it for my safety. When I pressed them again they blamed the captain. So which was it? I didn't appreciate either nonsense explanation simply because they didn't want to honor my request.

Great room between the seats, food was excellent, very comfortable overall and could have stayed on the plane even longer

Flight was great (only a short hop from London to Dublin). Wi-Fi available on board(around 2 euros), power sockets, complimentary water and biscuit. Landin/ takeoff all went without a flaw.

Staff member at boarding gate was rude, and more than once!

The issue wasn’t necessarily with British Airlines but was a reaction to their delayed flight from Miami to London on Aug 18. Due to the delay out of Miami, we missed our BA flight with Aer Linguis on the 19th from London to Cork, Ireland. The attendant in London was helpful and rebooked us for a flight later that same day ($120). However, she failed to mention that as a result of the missed flight, our returning flight was also cancelled and the rebooking cost was $451. Disappointed at the lack of communication between airlines and between the agent and the customer.

Lost bag on an hour and a half flight with no connections - ridiculous!

You lost my luggage on the trip to Dublin and again on the way back, still waiting on luggage.
