Lounge is nice, if busy. Finnair staff offered me a better seat at check in. Seats flatten out and have many features. Tons of convenient items all marimekko - nice pillows, blankets and slippers. Helpful and attentive staff, always check on you but also give you plenty of time to snooze. Nice skin products and omg, clean bathroom. Easy to relax.

The Asian vegetarian meal is rice and chickpeas! Was not too bad but also my breakfast was more chickpeas and grilled zucchini. I never requested a "vegetarian breakfast" - feel bad wasting food like this. I sent the veg salad back opted for fruit salad croissant.

KLM can't seem to figure out the order of boarding the plane. Should be business - priority - everyone else. Instead they do priority first, and that's usually two-thirds of the passengers. Also, really tired of the fake business class on these flights...

I was pleasantly surprised they had a snack service on such a short flight. The flight attendants were very friendly

Amsterdam customs is the most disorganized I have ever seen. With the number of tourists entering the country you would think they would have done something about it. There were only 2 customs agents!! One for all passports and 1 for all passports. We were in the customs hall longer than we were in flight!

From pre-boarding, to boarding, to the food, and the attentiveness, everything was top notch! The cleanliness of the plane was only topped by the friendliness of the crew.

The flight was marked at almost 11hrs but ended up being only 9...not a negative other than it meant not spending as much time on board!

Boarding was a bit confusing and staff wasn't actively being helpful with information. Got absolutely nothing to drink/eat on the plane-not even a glass of water! The flight crew was just ok, no one "stood out" as good or excellent. Again, nothing about this flight made me want to definitely fly British Airways again.

I made it home with my luggage.

Absolutely chaos boarding, seats way to close together in both width and length. They had open seats with more room, told me I couldn’t move seats but let others. Each leg of the flight the pilots landed like the plane fell out of the sky! The crew was yet again nowhere to be found during the flight. They do offer food for sale during the flight but it’s at outrageous Icelandic prices!! Never again!!!

Second time I have flown to Brussels with Iceland Air. I love their customer service and especially the flight route. My flight going over was cancelled due to weather. I called their reservation office , had to wait on hold for 1 hour and 15 minutes , but it was worth it. The reservation agent found me a new flight on LH, she explained I would get a conformation about 3 hours after our conversation with the flight information and new txt information. I was able to check in with LH on line that evening. Iceland Air had every pre assigned seats for me.

The boarding process in Kevlavik is pretty awful. No seating around gate areas. You have to stand in line for about 30 minutes to then have to get on shuttle to be driven to plane where you have to walk on stairs to get to plane, or in some cases you actually get to board from the terminal, which happened yesterday. I have MS,and sometimes standing for long periods of time and then having to climb up stairs is difficult for me. I also see a lot of elderly people and parents with babies having difficulty with this boarding process. Their airport really needs major expansion for the amount of people that travel thru their. Seating araes around their gates should be a priority.

Iceland Air itself is fine.

I had to buy the tickets through JustFly, which is an absolute scam and bilked me out of $750.

I liked the northern light atmosphere lights and the individual entertainment option.

My economy seat was a bit snug for an average built Person. I am used to being offered some kind of snack, but there is a menu with food and drinks you can choose from for a fee.

The flight was very bare bones. Entertainment system froze up half way into a movie. You had to pay for wine with dinner. Even on budget carriers, wine is included with meals on the long hauls. Half a cup of water was served twice during the flight. The cabin was kept quite cold. I wore thick socks and slippers throughout the flight, but had to use the small blanket provided to keep my feet warm. Glad I had a heavy coat! I will avoid this carrier on any long hauls in the future.

Dinner not too good. Breakfast very poor. Cold flight. Entertainment not working. Avoid for long hauls.

Crew was responsive and kind if something was requested but service without asking is no longer part of a transatlantic experience.

If you're on the Airbus transatlantic flight, the last section nis so noisy I'm surprised it's even a legal noise level. You can't even hear the entertainment it's so loud. Had to buy an upgraded economy just to be able to endure the long flight. It would be nice to see the cart come through again for coffee refill service.

Tried to reschedule flight just a few days later because of a friend's wedding. It would have cost more in fees to reschedule the flight than it cost in the first place, and THEN I would have had to pay for an entirely new flight. JustFly was absolutely awful to work with and showed neither remorse nor compassion.

The entertainment portion was the biggest positive. Crew was pleasant and non invasive.

Not offering any sort of complimentary food on a 7 hour flight isn't ok. Not being transparent about not offering any sort of food is worse. Boarding was confusing with separate lines, scanning our tickets, herding us into a room, then directing us to go upstairs, then over a ramp, then into our plane without any sort of efficient zone boarding.
