Bid process for upgrade is very frustrating. I was notified that I had won the bidding, then was told there was no seat available.

Bid process for upgrade is very frustrating. I was notified that I had won the bidding, then was told there was no seat available.

You cancelled my flight and didn't arrange another. Sent no info except YOUR FLIGHT HAS BEEN CANCELLED. HERES WHAT TO DO NEXT. and the rest of the email was blank???

Overall a great experience. I didn’t like that they didn’t assign seats until we arrived at airport. All the employees we interacted with at the airport and on the flight were kind and helpful.

It was ok but no WiFi I think I’ll fly Iceland air next time

I feel the service staff do not treat American customers well. I also feel there may be discrimination against minorities.

Yes avoid JFK airport at all costs. A horror to navigate.

All went smoothly. That's what I want on a long flight.

Overall, this flight team did a fantastic job. They came often with the water, coffee and tea. There was no meal choice in coach, but the lasagna lunch was decent. The sandwich snack just before landing was tasty. The baggage bins were large, so no trouble holding carry on luggage.

I child in Buisness cried almost the entire flight. And I had a conference to attend but couldn’t sleep because of that, which was the main reason for getting a Buisness ticket. Also the food is not as good as before. The sheets underneath is also not there anymore. The staff was nice.

Food was good. Flight attendants were friendly and helpful. We felt that a lot of the movies on board were old movies.

The ticket was reserved in my name but not paid for by underpricer. Alaska airlines was unable to issue my ticket (could not connect the ticket with the PNR) due to an error with underpricer and I spent the better part of 2 hours at the ticket counter trying to rectify.

Plus—newer aircraft, luggage arrived on time, adequate legroom. Minus-No snacks on three hour and five hour flights, long wait for a shuttle from the terminal to the airplane, indifferent flight crew

The flight itself was fine, even with a one-hour delay leaving on the Reykjavik tarmac (the lost time was made up during flight). Our experience at the Reykjavik airport on arrival was terrible due mostly to the one hour it took for passport control. Only two stations were open for our category, and the room was full with a huge crowd.

The real reason why the flying experience with Icelandair ---was mediocre was because of not being able to enter DC airspace yesterday evening. This obviously was out of your control and do realize this is a safety issue. I did notice---that everything was being done to get us to Washington Dulles and we did arrive at Dulles SAFELY with just a 4 hour delay. Thank you!

No food was served for 7.5 hrs flight. When our flight changed to other airlines due to wether issue, our seats booked with no checked in luggage when I already payed for. We end up to pay 90 euro per suitcase.

Bad. Flights were late, by hours. No clear information was provided even until the delayed boarding time.

The ground staff was very helpful and the flight attendant as short but good.

Horrible. I was placed on standby for no reason and they would no allow me to fix the seating into the gate. Plane was hot. Entertainment was abysmal. Seats only take old USB or even older jack plugs — not lightening plugs like all modern phones. Food is pay as you go and awful. Seats were small and uncomfortable. I do not recommend Iceland air.

Not good. It’s a terrible budget experience and the crew were not very helpful. The plane was so hot and uncomfortable and the entertainment was awful (not even headphones offered and antiquated jacks that don’t work with new iPhones). I was placed on standby for my flight home for no apparent reason, causing me to be put in the worst seat and at the end of the plane. They did not try to fix the situation.

So Iceland Air is one step above Spirit Airlines. They do not feed you unless you pay for it or are in Saga Class. So, bring your food. They have a drink service, but it's in a large Dixie cup. Ask for the can, that is the only way you'll get a real drink. Also, we missed our connecting flight so they put us up in a flea-bag motel. Don't get me wrong, the staff was nice and friendly, however, there was no shower gel or shampoo in the hotel. We have to go to the corner store to pick some up. The room was not in great shape. Holes in the bathroom, a badly repaired ceiling in the room. The window was warn out. So, you get the just of how bad it was.
