Our flight from SFO to MSP was right on time on 11/15/2025. No delays. As we approached MSP at about 8 pm, we circled in the air until 8:40 pm so I don't call that efficient for MSP. I think the captain should announce the delay and why. (as if we all don't know that we are just circling around the area, slowing down, speeding up, slowing down.) Thank you. Marilyn Fischer

Service in business class was not impressive. I ordered coffee with dinner and then watched other people get 2 refills before I got my 1 cup of coffee, and only after I pressed the attendant button overhead. Furthermore, the seats in the forward cabin need maintenance on this 737-800: the upholstery is detaching from the seat frame, at least on the backs of seats 1C, 1D.

The ticket agents in West Palm Beach on Friday afternoon Nov. 7th were incredible in getting us on an earlier plane to Atlanta during the government shutdown. Had the taken our original flight we would have missed our connection. She did this on her own, We didn't even have to ask, and she did it all with a smile and showing genuine concern that we would be taken care of. We are very grateful and thankful. We fly often, and now we will be sure to fly Delta.

the over had ligth did not work'd for the all way

Flight delayed then cancelled. Misplaced luggage. Still do not have. Rented car 1100 mile drive. I had to buy some overnight Hotels clothes toiletries gas food at my expense. Still not home. Not sure where luggage is. Over 4 hours on hold to Felta

I truly love flying with Delta. They have always treated me with the upmost respect

Our flight attendant in FIRST CLASS was one of the worst I’ve ever had. She was not at all pleasant, nor particularly good at her service.

Everything went well and was good. Nothing exceptional, but no complaints either. Cheap seats are pretty comfortable.

DELTA does a terrific job making sure you are well taken care of during the flight, gives you assurance before the flight through numerous email notifications about your upcoming flight & lastly good follow up after the flight making sure your needs were mat. It has been, is & will continue to be my carrier of choice in all my future travels. Good Job DELTA

Staff were friendly and happy. Delta could make sure passengers that don't have the app know of changes. Without Kayak I would not have known about the change of gate or the delay. Kayak was faster to notify me.

It was so hot on the plane. No air jets above the seats

It was a fairly old plane in which you couldn't buy an internet connection.

Scandinavian was perfect. Nice A350 with an on time departure and an an experienced crew. What a difference from TAP.

The staff were great, the food was good. I just hate being crammed in a tuna can for 10 hours cause I can’t afford a better seat.

Really like this airline. Best food for airlines and comfortable seats and attentive staff. Delay was due to air traffic.

Baggage was mis-handled; food and grocery items in the baggage were damaged.

I paid extra for our seats on the way coming back from Stockholm to New York the seats were changed and it was totally waved. This happened to three more passengers.

great crew, professional, funny, and great service. good condition plane too! great experience

When my flight was changed from delays they were quick to rebook me.

The seats have no legroom. I was bruised on my knees for having them pressed up against the seat in front of me. Then I got food poisoning from the special meal I ordered. Pretty horrible all around.

Again, we paid $ 328.00 for specific seats are were assigned those seats.

Never again. Terrible hospitality and human decency for an international flight. No food, no snacks, no beverages, blankets, pillows, limited entertainment. Tiny seats without any cushion and some do not even recline. I was shocked that they did not charge for seat belts. Never in my life have I witness asking for "spare change" for charity before landing on both legs of the flight. Icelandair can contribute on their own to said, so called, children's charity with the money saved from providing 3 centimeters of tea and water to hungry and dehydrated passengers.

Having been prepared for paying for everything on board other than water, coffee and tea the service was OK. Food and drink is expensive but the food was OK if limited in scope. Plane was clean and obviously well serviced. After complaining about having to walk in wind and rain to a get a bus to the airport the same thing happened at Portland. I’m sure you could get a terminal gate flight, complimentary food and drink for not much more money without traipsing through rain and slush in Reykjavik. Not bad but not great.

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

The boarding process seem to take longer than necessary, resulting in a 20+ minute delay

It was too cold in the plane my feet froze

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.

No meals included on this long international flight. Most airlines will offer you a meal when flying internationally. Not Icelandair. Your included choices are water and coffee. Poor customer service. The airport was also very confusing.

Excellent experience in every way, from ground crew helpfulness, boarding experience, inflight service all the way to modern equipment. My new favorite airline. I wish I could fly with them more often.

For a no frills flight this was surprising comfortable. The crew were helpful and nice. The flight was smooth and there were no delays or issues which I haven't had on a flight in a long time. I would definitely fly with them again.

The flight was canceled by play less than 24 hours prior to the trip, and I was unable to re-book. Have not received a refund for the trip despite filling out the appropriate form.

Was was cancelled less than 24 hours prior to my scheduled departure by PLAY. Despite my attempts to rebook my travel, I encountered significant cost increases that rendered this option unfeasible. In accordance with EC Regulation 261/2004, airlines are required to issue a full refund for cancelled flights within seven days of the scheduled departure if a refund is requested instead of rebooking on another flight. It has been three weeks without a refund or an answer

It would have been better to have USB charging ports available on the longer haul Flight that one of 2 hours

Was very good Staff was great. No tv monitors tho. So long flights make it longer

The worst. No free beverages. No entertainment on an overseas flight. Not enough space. Never again.

Play is affordable! Only way we fly from the states to Europe. Left late but arrived on time

have screens on backs of chairs...offer free snacks and water

Airline food is airline food, but the plane was wonderful and the seating comfort outstanding. One of my best flights in quite a while.

Crew was outstanding, helpful and friendly. Food is deteriorating. The snack at the end of the flight was not good, a greasy moosh of toast cheese snd other unidentifiable ingredients. Coming from Germany a pretzl with butter would have been better. Entertainment had a great selection.

Smooth flight with enough time for connection. Ran out of meal options. In-flight and gate staff were friendly and helpful. Good service overall.

The seat space seemed small especially when the person ahead reclined but other than that, very good.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

Give yourself over 2+ hours layover because if flight is slighlty delayed and you miss your connection, Lufthansa will do nothing for you

We would have missed our connection from Munich to Boston but we had a van outside the plan that wisked us to our terminal. Much appreciated and we didn’t even realize that Lufthansa had done this until the announcement on disembarkation. Well organized airline! Will definitely fly Lufthansa again!!!

Everything went well. I will fly with Lufthansa again. And use Kayak whenever I book flights

Bought a seat in a flight that got changed out so ended up paying for a seat I would have had if I hadn't paid.

Food was poor quality and the screens for entertainment didn’t work properly
