Great service, comfy seats on a greater than 10 hr flight. On time. Really solid. Thanks Aer Lingus
Didn't make it to this flight as we sat on the tarmac for 1.5 hours.
Caring & friendly crew. Most important: got us SAFELY to our destination!
One of the best flight experience I have had in along time. Would fly with them again.
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
I think the extra charges for seating with no added advantage and the added charges for baggage are excessive compared to other airlines.
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 worst Terrible Late for connecting flights. Made flight without luggage! I am still waiting for my luggage to be returned! I paid premium for this flight. My luggage should have been flown to Hartford instead they keep telling me it was put on a jet blue flight and is in New York! I flew Hartford to avoid New Yofk! The flight over was also unpleasant. We were stuck in a bus at Edinburgh airport for 30 minutes then our luggage again could not be found! Very poor service. Very disappointed . I need my luggage to be returned.

The space between seats has reduced even further making it extremely uncomfortable. Couldn't even open the tray table properly or got compressed the moment the front guy reclined.
The Glasgow to Dublin route was very efficiently boarded, flight and landing and disembarkation were all super smooth. Dublin to JFK flight I was very pleasantly surprised overall. This was my first time on Aer Lingus and having already come off the short regional flight I was curious to know how the international flight would go. Aircraft was solid, entertainment options were better than expected, flight crew were experienced and operated like clockwork. Main entree left a little something to be desired but the snack was very tasty. Boarding and disembarkation again very smooth and pilots got us in earlier than expected. Would definitely fly again
Great experience in Saga Premium. Food was tasty and felt fresh. Seat was comfortable (enough) - would have wanted a layflat seat.
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.
Was a bit surprised that Icelandair flies a domestically configured 757s on long-haul flights to Iceland (no lie-flat seats in business class).
The most uncomfortable seat i’ve ever had on a flight
Well! They got me as far as Iceland, let me wait around at the airport since my next flight had either left or canceled, finally gave me my luggage, and sent me to wait quite some time with seven other people for a ride to a hotel. At the hotel we got a chef's salad, a nice room for the night which unfortunately had feather pillows and duvet (allergies), a really great and spectacular buffet for breakfast (small but stunning), taxis back to the airport for the 9:30 Delta flight back to Minneapolis. The Delta flight has free food and liquor included which Icelandair does not. All in all, it falls far short of my worst ever United flight to SGN. Icelandair did change my reservation after my roommate tested positive for COVID and we canceled our plans to travel around Iceland, but the charges were fairly hefty. I had trouble contact Kayak's agents to discuss changing my reservations and finally contacted Icelandair who changed them. (I used their contact form and put in several requests for call backs.) Of course, they called just after I made the change with Icelandair.
