Hidden charges!!!! I was not advised until I checked in that I had to pay extra $90 for my ONE checked bag. Then, I was told that if I had paid in advance that I could have saved -20%. Then I was told that I would have to pay again on the return. And I could not pay at that time to get any discount on the return baggage charge. So the Kayak ‘discount fare’ wasNO DISCOUNT, only additional restrictions, like inability to select an isle seat for my long legs.

Price for the flight was nice from NYC - JFK to London for me. Useful to have budget airlines for further distances, if you don't mind missing large chunks of basic amenities. Bathrooms on this flight were more clean and nicer than most flights I've been on too.

I did not like the extremely long and inefficient way they board onto planes. They say they are starting to board and then we waited over 20 minutes just to hear who was going to board first. Then they ask for rows 18-28, leaving out the rows 29-36 or something like that, which created an extremely long and late boarding process. Once they started boarding people it was a giant mess in the waiting area and of course, once people have their ticket scanned, then you continue to wait in a long line past the kiosk for another 10 minutes. Getting Food, drink, and even the Customs Form was really inefficient -- the person with the forms walked quickly down the aisle and missed me because he was looking at the other side and not checking with each aisle like most flight attendents would. I ended up getting my customs form taking it from the drink cart when it was sticking out.

A 2-hour layover was too short. We experienced crazy long lines for: the bus between terminals, immigration passport review; passport review before the metal detector, and detailed tests on permitted volumes of shampo, and toothpaste. The agent forced me to check a normally permitted carryon bag, then the bags took 45 minutes to be placed on the turnstile after the flight. Not an efficient airport.

Very kind & courteous staff. Plane was new and very clean, with awesome touch-screens in the back of every seat. The movie and music selection was also excellent. Our flight was only about half-full, so people were able to stretch out in rows of seats.

It would have been nice if IcelandAir provided a meal for this transatlantic flight (or even a little bag of pretzels!), but considering the steal we got for this flight, it wasn't a huge deal. IcelandAir was generally fine. The customs process in Cleveland was atrocious. We had to go through TSA security again even though this was our final destination. Duty free items were not allowed through this security check; fortunately, one of the agents let my husband place our larger-than-3-oz liquids in a bag that was sent to the baggage claim. Especially for travelers like us who had been up for 20+ hours and flown across oceans, this was a source of significant stress and was generally terrible.

It was great to miss my flight and the plane was still in the hanger. There was no personnel there because the connecting flight was over a hour late and norweigen didnt composite for people in wheel chairs that was left to walk to the departure gate that was far and in another building. Really like to thst again never.

I didnt like on my way from newark to Rome Italy with a handy cap 80 yr old couldnt get out of the seat because the stewardess didnt know how to put the arm rest up so it would be easier for her and my self to get out to go to the toilet. Didnt like that diebetic food was delivered to thoes people in first rather with the rest. If u mark it then all should be the same.

My fiancée has allergies to food and the staff took good care of her and made sure that she was getting meals that had no triggers in them. For me the seats are always a bit too tight for people with real shoulders. It’s okay though I’m used to that. But then landing 40 minuets early was great. It allowed us to go through the border and still be on our way as quickly as if we were home in the states.
