Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

Delay, luggage didn’t arrive. Had to go the next day to collect it

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Seats actually fit a human! Snack options were a bit lame but that’s ok

Everything in general was great, but we left 30 minutes late

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

Flight was cancelled without notice or any reason given. I found out coincidentally when i was checking the baggage allowance on the app, When contacting the airline, the only option peresented to us meant we lost a day of our weekend getaway. Had a lot of contact with airline prior to flight, trying to get them to resolve the issue. We could have traveled the first stretch ourselves but the airline refused to accommodate this. The airline outright refused to be forthcoming in agreeing to alternatives that would let ut keep the date we had booked, and so a third of our holiday effectively vanished. This meant a lot of hassle, changing hotel nights, activities etc. Furthermore and after the flight, customer service refused to answer our complaint unless we used their very restrictive online form, which gave us no chance to properly explain what our issues were. They have of course denied our complaint, and so i have to bring the matter further. If you have an alternative airline to use, please do. SAS treats its customers as a necessary evil.

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.

SAS is very good at service, the lounge was great, and flights were on time. Boarding is fast and efficient!

Food was underwhelming. One free coke, charged $$ for one wine. Last year one wine was included. And prices were much lower.

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.

Unlike my prior three connections on this latest journey, this flight was fairly good. Only issue was boarding as it was once again one of those Icelandic issues of bunch up, walk in the rain to a bus that then has you run up three flights of stairs to board the plain. I was in Saga class but the bus scramble eliminates any chance you get on first and have to then find a place to squeeze your carry on into an overhead that the people in economy populate so they can grab it on their way out up front. But unlike other Icelandic flights this journey I did find more the of the business class like accommodations then the other air segments. This one found a pillow and blanket waiting for me and I actually received a small cup of sparkling wine and had a bottle of water in place. Service was attentive and the flight departed and arrived on time. Received a menu and had choices of a hot or cold meal. I choose the hot which was cod and it was good. Decent size portion, salad and a choice of dinner rolls. Beverage menu was a selection of wines, beer and soft drinks. Desert was a small Tiramisu. Overall the six hour flight was a good experience for the price point.

We paid for saga class, which is the business class for international. My seat was broken and did not recline and my monitor for in-flight entertainment was broken.

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.

Awful. The Iceland airport was a complete mess. Boarding was a chaotic, the seats were awful, there was a group of rowdy 20 something men in our row hooting and hollering, ordering alcoholic drink after drink. Yelling and laughing at the top of their lungs and the crew just went along with it. Passengers complained to the men, asking if they could keep it down (it was a night time flight so people wanted to sleep). They never listened crew continued to laugh with them, flirt with them and serve them more drinks. No free food or snacks, seats were horribly uncomfortable. Worst flight I've had in a long time

At least one soda free, felt like I was nickeled to death.

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!

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.

The cost for the flight was quite reasonable and transferring to a new flight in Reykjavík went smoothly. There was enough time to grab a bite to eat at the airport, and the luggage transferred to the new flight with no problem.

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.

I didn't have food nor entertainment. Lots of leg room and seat was comfortable

Bulkhead seats should not be an extra charge. They are extremely uncomfortable. And we missed our connecting flight due to slow luggage retreaval.

Lufthansa flight LH04414 from Munich to Washington DC, was fine. Efficient and safe!

Bumpy ride, not Lufthansa‘s fault. Crew managed a situation over a back rest to far down well. It was two iles behind me. The person putting the seat down, against the other person’s knees, was quite rude and belligerent and needed to be told in a no nonsense matter to stopp. Male flight attendant did good job.

Had a few open seats and could use it for a great rest ful journey

It was very good. Service was friendly and efficient, and food was good.

We left 1.5 hours late therefore missing my connection. The airline didn’t give vouchers.

Food could have something without dairy, I couldn't eat anything. Tv for both seats was malfunctioning. They have one bottle of ginger ale for entire plane.... and I paid extra for these seats...very disappointed

We took two long flights with Lufthansa, both were delayed making us miss our connecting flights. Lufthansa took care of the first one. The second was a switch to United and figuring out how to rebook was not a pleasant experience.

I came out early, 4 hrs before departure. The flight was changed 4 or 5 times with few minutes between new and schedule time , then 30 minutes delay, then up to 2hrs 30min delay. When I arrived in Frankfurt, no one help us to lead to the custom service. After almost 1 hour asking around then we must line up for another hour to get overnight and rebooking the next flight. We must find out how to get to the hotel by us self. The shuttle bus driver in Germany was not nice, speak German to English speaking and we must predict what she / he tried to tell us. We got up earlier and tried to not coming late to the check in and immigration procedure (we were told by the helping center that the immigration used to be over crowded) then we came there it was almost empty, then we must stay in the airport for hours not necessary. We got the coupons at the airport for compensation for waiting for delay flight for NOK 75 ( as low as 6 Euros) It is not enough to buy food at the airport price and Norwegian cost of living... How to drink a cup of cappuccino for NOK 72 when the stomach was empty for food in 16 hrs (from dinner at 6 pm the day before to 16 pm the day after) At the hotel in Frankfurt, we were offered two options spaghetti with biff or vegan food and a drink for 18 Euro. Almost 60 passenger ate the same food and I was remembered once time in former Soviet Union in 80's I travelled with Aeroflot and the passenger were stranded in the hotel for next flight and we were also offered only one choice of dinner, if we were hunger we must pay 1$ for 1 egg and another 1$ for two loaf of bread and butter. I can't believe Germany is to poor and inferior service like former USSR in 1980 decade. My good remembering of Luft Hansa disappear and changed totally by this service I got this time.

At Muchin the service woman for Lufthansa at the Airport was really horrible.
