The leg room in economy was sub par, everything else was fine.

The leg room in economy was sub par, everything else was fine.

Friendly flight attendants and reasonable good food. Quick service throughout the trip.

I WAS CANCELLED ! I thought entire flight was canceled but it was still ongoing and I was only canceled as a passenger and one day before my flight with really poor "choice" of next flights that completely ruined my family event. Absolutely disappointed by SAS. Will be avoiding this airline now

The flight was pleasant with landing and take off being very smooth. Toilets were a bit busy at times but crew was very accommodating. Food service was quick and hot. The connecting short flight was full and there was not room for hand luggage.

Flight crew was very kind and polite. They had to deal with an unnamed issue right beside me, and did so with respect.

Good flight. Mass boarding. Seats fairly comfortable. Food okay although may have upset my stomach a bit.

The crew were nice and courteous. Exonomy seats were worse than expected. Overhead bin space was non existent thanks to loose enforcement of the carryon size and letting passengers put up their purses jackets and backpacks up there leaving no space for others with a small conforming carry on. Food was not good at all. Perhaps worse chicken I ever had in my life. I had to have them take it after tasting how bad it was. Whoever made that should not be in food making business.

The crew was very helpful and friendly. Food was good. The only issue was the legroom -- not great. The seat in front is also too close to see the entertainment screen properly.

No crying babies the whole flight would be nice. Impossible to sleep. No free snacks , only the main meal

The crew was amazing. Our seats was not very clean and even that was not a full flight but our seats was right beside the WC which did not let us to have a moment of rest.

United, from whom we bought this code-shared flight, mid-flight canceled our tickets for the rest of our itinerary, without explanation. After long delay they tried to re-issue the tickets, but Air Canada could not find the re-issue. It finally resolved after escalation to several layers of supervisors.

Plane arrived an hour before departure. Plane was completely boarded and ready for push back when they decided they needed to change a tire. 1 hour delay on the plane when this could have been done before we got on the plane.

Usual wait for over a half hour for a gate at Ohare. They tell you you'll get there early then sit on the plane and wait almost an hour

I enjoyed it, again I believe air Canada has better seating options and better drink options

It was fine for the most part. But the volume on the announcements was way too loud, and the cabin temperature was chilly. We had the hardest landing I've ever experienced- I think it hurt my back, and the tires squealed when we touched down.

Upset about cancel to St. John’s and no overnight accomodation

Not a United thing, but late afternoon departures from Denver with thunderstorms is always prone to delays.

Really delayed, no effort to support customers other than “sometimes we run late.”

The flight was excellent. Their was no service as we boarded, the flight attendants spent about 30 minutes just taking and not really caring that the cabin was about 80 degrees and did not offered any beverage to first class passengers or any passenger. The flight from DEN to ONT is not long but not under an hour, we received one drink and bag of chips if you were lucky. I was in first class…. I did leave my hat on the plane and it only took less than five minutes for a United rep to locate and bring it to me.

Flight was late to take off Plane broke down Had to move everyone to another plane Told we weren’t going to LGA but Newark Also told we would be taken to NY But United lied and we ended up at Newark at 2 in the morning Horrible experience. And the experience of trying to get compensation from United is just as bad. They could not care less about their passengers Never again!

Only coffee, tea, and water were complimentary. Seat did not recline.

EVERYTHING was charged for. Continuous Iceland advertising; it was off putting.

Overall professional and reliable; only complaint was the lack of complimentary food or beverages on the flight. I’m not accepting an upcharge on things one can reasonably expect.

Movies were old and third rate. Very poor on a seven hour flight. Food was OK but not business class caliber

Although the flight from JFK to Keflavik is not inexpensive, Iceland Air offers nothing but water, no soft drinks, to passengers without a charge. The seats are uncomfortable, there is no leg room, and there was no available internet to purchase.

Crew was very friendly. Need lay flat beds! More snacks

Good. Rxception is the Entertainment - movies and TV shows all out of date…

I paid for our seats and when we boarded and went to our seats it was the last row. I would have never paid for my seats knowing I’m sitting in the last row. The airline must have moved our seats and I didn’t realize it when we checked in.

Problems checking in both on the laptop and on the app. No free seating available at check-in as advertised - must pay for EVERY seat between $23 and $75. No way to cancel seat choice. App menus and site menus are not responsive, and some items are impossible to find. Crew and mobile assistance are friendly and helpful.

Iceland air transfer was bad. They lost my luggage and I just received it 11/1

The tv and remote didn’t work. The plug to charge our phone didn’t work.

Very, very tight legroom. They must’ve jammed in an additional few rows of seat seating. Denver to Munich was the least legroom I’ve ever had on any flight, let alone a multi hour international journey. I will not take that flight again.

Very good, i got two seats for myself, and was comfortable with the blanket i got

Food is too little (in volume) and too spicy.. There are no snacks in the back of the plane in between meals.

We had a 1 1/2 hour delay before we left Denver. When we arrive to Frankfort, they didn’t announce that people with connecting flights to exit the plane first. My next flight was already boarding when we we taxiing in to the gate. I waited another 10 minutes to get off the plane. I had to run to catch my next flight. I mean run! I made it with one minute to spare, but my luggage did not. My luggage came two hours later on a different flight.

Both flights were delayed and we missed our connection. Our second flight was delayed 3 times. I have always had great service and never any problems with my flights on Lufthansa. My last two flights were, unfortunately, awful. I fly quite often to Germany and have had better luck with United than Lufthansa.

Excellent staff and flight experience. Would rather that I had upgraded to Premium Economy for extra space, but I will know to do it next time.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

Sorry, I’m not a fan of United. The seats are just too cramped and uncomfortable if you are traveling very far.

Zero legroom or space in economy. Flight was delayed into Munich causing a missed connecting flight and other missed bookings. :(

It was my experience w Kayak that was negative. I’m never using kayak again

Work being done at DIA made it difficult to find BA desk.

I’ve never been on a trans-Atlantic (or Pacific) flight where the seats don’t recline—not even a little. I asked my seat mate when BA starting doing this and he said “Oh, a few years ago.” I couldn’t sleep, with my head falling forward waking me continuously, and came off the plane incredibly stiff. I booked a Premium Economy seat to get a more comfortable seat, which was worse than most basic Economy seats I’ve ever booked.

The gate agent made me check my carry-on in Denver, even though I've traveled all over taking this case on the plane. Beware folks. Food in Premium Economy was quite good - excellent blanket! Flight attendants on the Heathrow-to-Budapest flight on 3-27-2026 were quite snappy. I got a frown when asked to unscrew the water bottle cap for me (I had a cast on my right arm). Also woke up right when they were handing out biscuits. She had given my rowmates one and was in the process of giving water when I asked for a biscuit. She scolded me and said, "You snooze, you lose". She did give me one, but I thought that comment was uncalled for.

Seating and food was the worst we have experienced in 35 years of traveling for both personal and busines .

Everything was very good! I personally struggled with the heat in the cabin for the first 2 hours

Flight was delayed. Though I checked in with BA live chat three times, our special meals were not provided.

Was 3 hrs delayed and my poor friend I met in Barcelona was waiting at airport for 3 hrs. Dallas airport was awful

Late in leaving the US. Late in arriving in UK. 2 plua hous on ground in UK before leaving. Late in arriving in Spain. Didn't get our bags until the next night.

Comfortable, pleasant staff, quiet, good entertainment, food, drinks. Better than American (flight back) when we were crammed in and staff sometimes indifferent.
