I was surprised how good an American airline can be - I was really impressed.

Cut out the nickel and dime pricing for "seat selection" and baggage, To do this on an international flight is just mind boggling. Seriously, why treat customers this way??? Nobody wants these hidden extra fees and everybody hates them. Also plane was too warm and no air vent, and water dripped from the ceiling at one point,

I have paid for extra legroom on my flight. My seat was broken and did not recline. The crew could not fix it and refused to provide me with another seat

It was so hot on the plane. No air jets above the seats

Scandinavian was perfect. Nice A350 with an on time departure and an an experienced crew. What a difference from TAP.

The staff were great, the food was good. I just hate being crammed in a tuna can for 10 hours cause I can’t afford a better seat.

The Scandinavian flight was excellent, however the second flight was partnered with TAP Portugal which was not so good. crowded gate area with no chairs, delayed flight, bad boarding process, no entertainment system onboard, and the baggage didn’t get to the carousel until well over an hour which caused our taxi that was waiting to leave. Love SAS, hate TAP.

Really like this airline. Best food for airlines and comfortable seats and attentive staff. Delay was due to air traffic.

Service, food was outstanding. They make every effort to make sure that your long flight is as comfortable as possible. The only reason I did not rate them excellent is the way they handled our cancelled flight. They were great about re-booking except for the hotel. A communication breakdown ensued regarding who was booking the hotel for our overnight stay: the city where the flight was cancelled or the city where we were going to lay over for the night. In the end, neither of them did, so we ended up doing it ourselves and were extremely lucky to get a room at all. Given that, I still would not hesitate to fly with them anytime.

I paid extra for our seats on the way coming back from Stockholm to New York the seats were changed and it was totally waved. This happened to three more passengers.

The Experience Was Torture Spend a few extra dollars and avoid Icelandair at all costs. There is absolutely no refreshments, no food, no drinks. Only water, coffee, tea are free and at only half a tiny cup. Entertainment is limited selection of films, shows and mostly outdated. The seats are smaller than usual, with no cushion, no pillows, no blankets. First time in my life have I witness an airline asking for donations in spare change for a charity. With all the money Icelandair saves by starving the passenger, they can afford to give this charity on their own.

Again, we paid $ 328.00 for specific seats are were assigned those seats.

Having been prepared for paying for everything on board other than water, coffee and tea the service was OK. Food and drink is expensive but the food was OK if limited in scope. Plane was clean and obviously well serviced. After complaining about having to walk in wind and rain to a get a bus to the airport the same thing happened at Portland. I’m sure you could get a terminal gate flight, complimentary food and drink for not much more money without traipsing through rain and slush in Reykjavik. Not bad but not great.

The boarding process seem to take longer than necessary, resulting in a 20+ minute delay

It was too cold in the plane my feet froze

Service was excellent. Food and drinks were very good except for a greasy lump of a donut at the end of the flight that left us both feeling internally disgusted.

Handling our luggage was the biggest issue - they lost it and we got it almost 3 days later. Really threw off the beginning of our trip and we really had to change our itinerary accordingly.

No meals included on this long international flight. Most airlines will offer you a meal when flying internationally. Not Icelandair. Your included choices are water and coffee. Poor customer service. The airport was also very confusing.

I flew Icelandair with my partner from Prague to the US. Overall flight time was around 12 hours, with a connecting flight in Iceland. I have flown internationally for years and with multiple airlines. Every airline serves you a meal when traveling internationally. Icelandair not only did not offer an inclusive meal, but they did not even offer a snack. The only things they served over our long flight was water and coffee. Ridiculous! Never again will I fly with Icelandair.

It was good. The air plane is clean and staff were friendly.
