They were so kind to us! The entire staff were so good to us when we had our service dog join our trip and we couldn't be more grateful!

They were so kind to us! The entire staff were so good to us when we had our service dog join our trip and we couldn't be more grateful!

Larger seats and more room would elevate the experience. Otherwise, it was good!

Flight crew and flight were good. But it departed two hours late.

They changed our flight from a one stop 3 hour layover to a non-stop. Saved us hours and got us there sooner.

The ground crew did not supply drink or snacks during the layover in SFO. So there weren't many options. Otherwise, it was all great.

The check in Process was a bit slow. The flight was smooth and comfortable,

No accommodation or credit offered for cancelled layover flight to Eugene from portland

I love a red eye flight. No lines to wait in. Lots of turbulence on the flight and a very shaky landing.

I truly appreciated the kindness and attentiveness of the staff and flight attendants. They did their best to be prompt with departure times to San Diego and back to New York! Alaska Airlines ... you are awesome!!

Flight from PSP delayed ~2hs and missed connection. Terrible service providing acommodations & food (no rides - just the hotel van every 30 min, which you have to call). 12 dollars in food for a 9 hour delay. 30+ minutes to get everything sorted out.

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 Entertainment is limited selection of films, shows and mostly outdated.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.

If there was a disclaimer regarding food service or lack thereof, l missed it. If l had known l would have prepared better. Same with transferring at Reykjavik. No information about disembarking via stairs into rain, slush and puddles deep enough to swallow a foot. After being treated to haute cuisine restaurants and warm inviting environment during the flight, the airport is, let’s be kind, disappointing. Plane was comfortable, Airbus, staff were welcoming enough. I would likely try the route again. Maybe have a night and day in Iceland. Maybe not.

They had a 4 hour delay and left my luggage in Iceland and it didn’t arrive in Portland until 11/1

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.

Seat was hard and uncomfortable and the temperature too warm and uncomfortable.

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.

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!

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