Cons: "Too much nonsense with carry on and check in language. I paid for my seat but they changed it for better balance of the plain. Really I weigh 165 lbs. Once the plane reaches altitude they let me take my seat. However the plane was barely occupied and somebody with closer and took my seat."

Pros: "The airline is top notch and treated you great like it should be."
Cons: "The sears where a little tight but not bad and the movie options were ok not great."
Pros: "Nothing"
Cons: "Entertainment didn’t work, the crew did nothing to help. The plane was hot and stuffy. My luggage is lost."
Pros: "The crew service was very good, as was the food. The only complain is about the entertainment, hope to update the touch screen."
Pros: "Amazing - they had a full dinner for a 9:55pm flight, with real silverware, complementary alcohol, for economy passengers! Crew extremely professional and efficient."
Pros: "I did not receive a single email from kayak letting me know I could check in or select seats. No updates on flight status! Poor service!"
Cons: "Email updates before flight! Not a single email sent!!"
Pros: "Excellent service from the crew and prices were good."
Cons: "The seats seem to have gotten smaller and were rather uncomfortable for a 7 hour flight."
Pros: "Crew was great. Phenomenal even."
Cons: "Economy seating, so hard to complain, I got what I paid for, but 1-2” more between seats would have kept my knees out of the lady’s back in the seat in front of me..."
Pros: "Crew was fantastic"
Cons: "Boarding was delayed by 30 minutes. May have been beyond the crew control."
Pros: "Crew was very nice and attentive"
Cons: "Leg room on my first flight (longest leg of the trip) was not much and when the person in front of me leaned their chair back, my knees were touching the chair."

The staff was very professional, the places very clean. The legroom was a little bit tight but so worth the price of the flight. Very pleased! Next time, I want to book a stayover to explore Iceland :)

The boarding process was easy, the crew was friendly and the flight was very smooth. There is a limited menu the food was tasty, but you have to purchase everything. The cost of the flight was very reasonable but everything such as baggage is extra.

Play is a great budget airline. There are no TVs or chargers in the seat but there was more legroom than expected. Boarding and all staff that I interacted with were great. You have to pay for any and all drinks or snacks you might want on flight.

Play is a great budget airline. There’s more legroom than expected, no TVs or chargers in the seat, all staff that I interacted with were great.

Blood sucker budgeted airline. Charging after and after. No one should busy air ticket in this airline. Completely a scam and sucking blood.

The cabin crew very kindly arranged a change of seats for us due to a distressed passenger

There was no food or entertainment. That was fine, not a problem. I paid for “priority boarding” ( and a cabin bag) but there was no “priority boarding.” That was disappointing and falsely advertised so perhaps that could be adjusted.

No frills airline. Excellent service. Very good leg room for passengers compared to other "full service" airlines. Crew was very friendly. No entertainment system other than flight information display which was surprising as I thought it would be another revenue stream for them. Overall a surprisingly excellent experience.

Great new carrier to Europe. Lots of leg space and friendly crew

Worst seating -- by several orders of magnitude -- on any aircraft in sixty years of flying regular and budget airlines. The seats are cramped from side to side, barely padded, short from back to front. Tightness was at first absurd and then actually painful for a five-to-six hour flight. Pitch between rows is so small that even turning to stand up to get into the aisle is difficult. And I'm a slender guy, 5'9", 170 lbs. Website for booking held many "mysteries" like hidden access to payment portal. Though one screen said my booking and payment were complete, I learned at the airport that "complete" was not true. Had to work with helpful supervisor at the check-in desk Online I was able to change my flight booking from Saturday to Friday, But also I learned at the airport (too late) that the carry-on bag fee from the Saturday flight did not automatically shift onto the Friday flight. I had to pay the much higher at-the-airport charge, 49 euros. I will try to get an adjustment.

Pros: "The flight from EWR to MSP was extremely quiet. No loud engine noises."
Cons: "We were vert disappointed at the Newark Airport - the Delta Club was closed and there had been no notification prior to arriving at the airport. I certainly missed that early morning coffee."
Cons: "The crew was overly aggressive with mask policy enforcement. They patrolled the aisles and routine pointed at passengers directing them in a hostile manner to keep their masks on their faces, even when they were trying to eat or drink. They also threatened customers by stating it was a federal law several times. It was very uncomfortable to say the least. I will not fly delta again by choice."
Pros: "Friendly cabin staff and one of the most enjoyable addresses by a captain I've ever heard (and seen - he was out in the first class area when he welcomed us)."
Cons: "Nothing"
Pros: "Check in at the airport- Delta is so friendly and helpful!! Flight crew was wonderful"
Cons: "Seats are snug"
Pros: "Crew was friendly and engaging"
Cons: "I wiped down my seat area to clean it. It would be nice to know what Delta is doing as well."
Pros: "Crew was great. Seats were comfortable enough. Delta inflight app worked well for entertainment. I will even brag on the fact we took Offa full hour late but somehow landed 5 minutes after scheduled."
Cons: "Departure time"
Pros: "Crew was exceptionally nice. Live DISH TV unexpected and appreciated."
Pros: "Pilots kept us abreast of timing and upcoming turbulence"
Cons: "The seat back screen was broken, but the screen itself was always on, so in addition to no entertainment, I couldn’t even have darkness"
Cons: "Flight was freezing. Crew was overly concerned about my tree nut allergy. Been flying for 40+ years and this was the first time any one has asked...appreciate it but they went overboard"
Pros: "The crew was very attentive and had great personality. They anticipated any needs we had."

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

Pros: "I liked how generous they were with food and drinks"
Cons: "Free WiFi could have made the flight a lot better"
Pros: "Boarding was efficient and the crew were nice."
Cons: "the seating is horrible. it was the tightest seating I've ever experienced."
Cons: "No internet available (2020). For the my previous flight, a month ago, was the same problem."
Pros: "Very friendly and responsive crew. Announcements from the Capitan and chief of flight attendants are very informative and comforting. Seat positions: very good leg room (even in economy)!"
Cons: "Newer airplane, as 747s are kind of outdated now, especially for long distance flights. But overall had good experience with KLM"
Pros: "Great atmosphere, crew was excellent!"
Cons: "I’m 6’5”, so legroom can always be a complaint, but this wasn’t too bad. The plane appeared to be fairly old and didn’t have WiFi. Entertainment also was on an older screen which was navigated by using an old in-seat phone."
Pros: "Crew were excellent"
Cons: "Old aircraft. Uncomfortable seats in economy. Entertainment screens old and almost impossible to watch - watched my iPhone! No mobile phone charger."
Cons: "Boarding was crazy. Could not everyone in the gate area."
Pros: "Onboard crew were nice and polite. Flight was on time (a rarity)."
Cons: "The boarding crew was rude and unpleasant, the plane was boiling hot."
Pros: "Seat was good"
Cons: "Depart on time (1 hour late), hostess put a laptop in the overhead, which fell out and hit me when the bin was opened"

Very bad turbulence for half of the flight,only 75% of the passengers were served a meal as the turbulence was so bad,crew did a great job.

My experience was good but we left late from NY and missed our connection to Palermo and were rerouted through Zurich. We went from Zurich to Palermo on Swiss Air. The representatives at the gate harassed us and would not let us bring on our carry on bags stating the plane was fully packed which was not true. There were many empty seats and plenty of over head storage. I have never been treated in such a way.

Cons: "This was one of the worst Lufthansa crews. You could not pay them to care. Many years of flying LH this is the first time I encounter such poor service."
Pros: "The crew was Ok except at the beginning when they could help more inside the plane with finding the seating."
Cons: "I missed the plane shopping because i don’t recall seeing the crew after the meal offering it. I heard the announcement at the beginning of the flight so I was looking forward to make purchases. Later when I asked it was already closed."
Cons: "All of our luggage was lost and did not arrive in Prague"
Cons: "Tv screen didn’t work very well. ( picture was fine but the function buttons were terrible)."
Pros: "My flight was delayed four hours, so I missed my connection to Sofia and had to re-book for two connecting flights instead of one, which makes for a long, tiring trip."
Cons: "I understand the delay due to weather conditions, but I wish I was rebooked for one, not two connecting flights. Now, instead of flying directly to Sofia from Frankfurt, I have to go to Munich first and then to Sofia, which makes my trip 9 hours longer"
Pros: "The downstairs bathrooms were great: five roomy clean bathrooms, always one available. The crew was superb, professional, kind, capable. The entire trip was perfection. The timing of both flights, the airports, it was travel at its best. We love Lufthansa. We have tremendous confidence in them."
Cons: "The food was just okay. A better choice of wine and greater selection of spirits would be nice."
Cons: "They told us there were no earbuds so recommended using our own. Our children had left theirs at home so they ran to get a $20 pair nearby. But the the plane DID have the buds; what we did not have were blankets — the crew said none were to be had."
Pros: "Very friendly, helpful and communicative crew."
Cons: "Only complaint: the touch screen on the seat back was oddly unresponsive and this made it a bit difficult to interface with the various in-flight entertainment options; the streaming music in particular."
