online check in was not available so i had to get to airport extra early. The flight was delayed and my luggage was lost. I had an argument with the person behind me who wanted to keep her bag on the floor and not allow my seat to recline on a 9hr plus flight. So overall, lots and lots of areas for improvement.

We were given vouchers we couldn’t use with a 5.5 hour delay

The flight was operated by Lufthansa. You can't expect much from them anymore. They have a talent in getting something wrong.

The food was the worst I’ve had on any flight I’ve ever been on.

I fly UAL 7-8 times per year. This flight was not up to snuff because it boarded very late "due to unexpected delays in restocking the plane" and yet Flight Aware showed the plane had landed some 10 hours earlier--so I think they could have planned accordingly. The FA's were nice but harried. The video system had to be rebooted 3-4 times. The food service was rather abrupt; they forgot my row and when I asked for my meal, they brought it with some impatience. Overall, the flight was fine, but the little details made it feel somewhat mundane and hurried.

The seat and leg room was not good. The food and beverage service was good.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

Flight was cramped with every seat taken. The food was fine, nothing crazy to write home about. The plane felt dated and needing some TLC, the button for the window shade didn't work and there were no AC outlets to use. When communicating with staff all except one nice lady never seemed happy to help me almost like I was bothering them when asked for things like a glass of water or a snack. The flight was overall fine. It did what was needed which is get me from point A to point B. But it certainly was not special. I don't expect much in economy but I believe economy on a host of other airlines is more memorable and better experience.

Great experience. Typically do klm to Amsterdam but may start taking this flight in future - greatxexperience.

The food was wonderful! The blankets and pillows were a nice touch and the staff were very accommodating, making frequent rounds to offer food, drink, etc. We were also told in advance when to expect meals to arrive, which is thoughtful. I liked the early notification about the lack of headphones as well, although unfortunately I'm not sure we received on for the first leg of the trip, which would have been nice to prepare for. The seats are a bit tight, and the bright monitors on the wall were on during an overnight trip, making it difficult to sleep for those close to them. .

The check in not ok! Demanding that we check our carry ons on check in! When there was plenty of available space inside the plane! And the staff at check- in was rude and not helpful and I was traveling with my autistic son and his service dog! Boarding was easy since we were priority boarding! The crew was ok expect from one guy flight attendant that was actually great!

Crew was unresponsive to request for a soda. Food was horrible and I’d venture to guess many others thought so as well by the amount that they trashed. Made me sick to my stomach and ended up in bed the remainder of the day once we arrived. Screaming child for 3/4 of the almost 8 hour flight. Crew had no headphones whatsoever for free or purchase. Seating way too tight and we upgraded our seats. I do not see us ever flying this airline again.

Standard short hop flight. No food, no entertainment. Just get in, get something to drink, and try to be as comfortable as you can for an hour.

Cancelled my flight. Only option had a layover in Italy. No compensation for the 4 extra hours of travel time. The travel agency, cheapflightfares, blamed Scandinavian airlines and said there was nothing they could do. Scandinavian airlines said since it was booked through a travel agency there was nothing they could do. The entire thing was incredibly frustrating. Never booking through kayak or with Scandinavian again.

Sat on runway for 1.5 hours waiting on winds to change so we could take off. The pilots did an amazing job getting up in the air when they had permission to take off.

The seats were really cramped. The high backs on the chairs made you feel claustrophobic.

Boarding was chaotic and the flight left late but arrived at a decent time. This may have been because of the sxsw festival that was going on.

I was pleasantly surprised as it was my first time flying with them. The seats were comfortable with more legroom than usual. The service was great too! The entertainment was good but could use a few more new movies.

Everything was good. Only issue comes from being vegan and flying. The food options are super limited.

Overall good for an economy fare. IMO the movie selection could be improved. Great that you can now connect bluetooth headphones to the entertainment system.

For a four hour flight, I was disappointed that everything was for purchase except for coffee, tea, or water. The disembarking in Iceland was so inefficient and time-consuming. We landed and stopped in the middle of the tarmac, had to disembark in the rain, and then squeeze into a bus which took us to the airport. Crazy! How does that work in winter?

Paid for a Premium seat...minimal recline, no footrest. Maybe slightly wider than a cheap economy seat. Zero chance of getting any rest on this plane

Comfort of seats is not good. Like sitting on a rock for 6 hours. Also no in flight food and limited beverages unless you pay is not nice. Need flight to be dark during the “night” but attendants don’t ask for shades to be lowered..

Seats in premier saga class were narrow and hard. Very uncomfortable for a 5-hour flight.

Iceland airlines doesn't provide any meal on flight to and from New York, except water and soda. Airline over charge for checking in luggage. I'm really upset. If there is option to use another company, I suggest to other people use them.

The seats on this airline are sooo small, even for a petite person. I felt like the seat tilted forward and I was fighting to stay in it. The lavatory is horribly small, with a wet floor because the sink is so small you can't help but splash the water all over when washing up.

Smooth efficient airline. Think they should have their own bag drop as the queue took 30mins to bmscan and drop

Good. Lacking overhead bin space. No food offered but you can order online or in flight and pay for snacks.

Flight was great only departure was delayed to saome ground crew issues

It was freezing. I asked crew member for a blanket and was told it might be in front of plane but I never got one. I turned off all the vents but still froze.

Flight was 1.5 hours late to depart so changed flights to Swiss Air.

The United Airlines crew that operated this flight was subpar. They didn’t

Very small and uncomfortable seats, Hard to hear entertainment system sound. Horrible food. Staff doesn't care much about the passengers. 2nd time they didn't give me my vegetarian meal. They asked me regular food with meat. The airline and staff was from United airlines.

Checkin took along timen only.few angents available at.checkin desk. Customer support over phone no existence

At baggage claim, I was given the wrong printed ticket. The ticket belonged to another passenger for a different flight — to Zurich instead of Frankfurt (layover). I was even allowed to pass security, and when I asked the Lufthansa employee if I was on the correct flight, and why it was changed. The employee said everything was correct and I should board. When I got on the plane, there was someone in my seat, and the crew on the plane finally realized that I was on the wrong plane. When I got off the plane, nobody was willing to help, and the security refused to provide my original printed ticket. That was until I showed them that I took a photo of the ticket; once they realized I had photographic evidence, they were suddenly ready to help me. The Lufthansa employee began communicating with other airlines and found a flight that would take me to my destination via Polish Airlines. I was required to once again go through security, re-check my bag, and once again pay for my checked bag and weight overage fees. This experience was incredibly stressful and very frustrating, as you can imagine. A Lufthansa employee told me I would be eligible for a refund. Please tell me what steps I need to take in order to make that happen. Thank you!

The row of seats were so cramped it was difficult to get in and out of your seat. I even upgraded. A long flight and sad accommodations 😵‍💫 the shorter flight was very comfortable and the seating was spacious

I bought a ticket and paid for for our luggage but I had to pay for my luggage again. I’m so disappointed! We had a 30 min delay and because of that we missed our connecting flight and were told that we would be on the next flight (9am flight ) but we were landed we were booked at 12pm flight. I had a little baby w me, it was very stressful. I begged to leave at 10 am at least. I was emailed that we get a voucher but they didn’t work when we were at a breakfast store. I’ve been always happy w Lufthansa but this time was awful.

Good service … bus transfer upon arrival from plane to terminal: atrocious!!!

Seats were not comfortable, and the problems started when we landed at Frankfurt airport. We waited more than 3 hours to collect our luggage, as a result we missed the connected train to Brussels. Our plans for the trip were ruined that day.

I missed my connection in Frankfurt and was booked to another flight to New York. Different destination and got downgraded from Business Class to economy. No Support from Condor at all. Very Bad experience

Flight 1.5 hours late; missed connection. Ground support for rebooking inadequate to the point of ridiculousness.

Flights delayed, and not communicated to the level I accustomed to by other airlines. The crew seems to be hating their job and it shows. It costs you nothing to smile and be a bit more friendlier. Also, no jet bridge, passengers have to use stairs, which is hard for my elderly parents. What's the point of ordering wheelchairs?

One of the stewardess was really rude to a customer right near me. I ordered water and was given sparkling water which kind of surprised me as I've always been given still water but I didn't say anything. The lady after me ordered water as well and when she saw it was sparking water, she stopped the stewardess who then said very curtly "You could have told me sooner." Whoa...that was rude! Later this same customer had some liquid spilled on her as the same stewardess handed a drink to the person sitting next to her. I know it wasn't intentional, but it was rather strange. It was very hard to navigate how to get through the Frankfurt airport to our connecting flight. No one told us you'd have to go through security again so it was rather confusing as we didn't have a boarding pass. Luckily we were able to get necessary papers and get to our flight. Sadly, my luggage did not make it out of Frankfurt though.

Quick easy flight, checked my bag and was told to pick it up in LAX but my bag stayed in Frankfurt. I am tracking it with an air tag. I filed a complaint with Alaska Airlines at my last stop in SJC.

For context: 10 hour flight FRA-YVR. Newer A330 Neo plane. Crew were amazing - friendly and efficient. The plane is newer with great overhead space. My main issue is that the Premium Econ cabin is inferior compared with other airlines. Cute amenity kit (a plus). Food was fine, though I’d like to see more wine selection beyond 1 red and 1 white. But, seats aren’t as comfortable, and all Prem Econ and Econ passengers share only 4 washrooms. Washrooms in business are off limits. In addition, Condor charges for seat selection in Prem Econ. Ridiculous on a $1500 one-way ticket. Prem Econ configuration is 2, 4 and 2, and Condor put me and my partner into 2 middle seats in the group of 4 seats, meaning we’d have a single person to our left and to our right. Again, ridiculous. A kind airport agent was able to give us 2 seats in first (and exit) row of Prem Econ but these had no footrests. I wouldn’t rush back to Premium Economy on Condor.

The crew was friendly, but the comfort of the plane and the food definitely had room for improvement.

The cabin staff was very friendly and attentive. The plane was modern and fairly quiet in flight. The video screens are large and of high quality, and I liked that the documentary movie "Anselm" was available for watching.

The flight from Saskatoon to Calgary was canceled by WestJet due to the airline strike. Condor, as the main operator, did not inform us. We found out that information just when we arrived at Saskatoon airport. Fortunately, we had enough time to drive to Calgary airport and catch the flight to Frankfurt. We couldn’t claim compensation for the missing flight because nobody takes responsibility for this situation. When we tried to contact BudgetAir, they redirected us to Condor, and Condor redirected us to WestJet. WestJet keeps saying that they are not responsible for the ticket that was bought from a third-party company.
