Cons: "Weak selection of TV shows for entertainment, but movies selections were very good so overall not a real problem."
Pros: "Everything!"
Cons: "What’s not to love?"
Pros: "They were great with service"
Cons: "Having to have to close my window shade so I couldn't see outside"
Pros: "I had to pay a premium more to sit with my family to sit together in cheap seats."
Cons: "I did not like the treatment of being a star alliance gold member then getting gouged even more for sitting together with my family in their cheap seats. My bags were marked with a priority tag, which meant nothing other than my bags being the very last off of the turnstile in San Francisco. One other passage stated that Luftansa does not care abut this aspect of customer service, which is obvious."
Pros: "Good food, service. Love that toilets are downstairs"
Cons: "New planes are smaller and more cramped"
Pros: "Comfort and space"
Cons: "Plane was scheduled to depart at 10:30 and didn't leave ground until 11:40, unacceptable."
Pros: "See above. The same applies."
Cons: "See above. The same applies."
Pros: "All worked as expected"
Cons: "No remarks to make"
Pros: "Travel time was good and easy travel"
Cons: "Entertainment tv tapes"
Cons: "My flight schedule changed after I bought the ticket, which resulted in paying for the hotel for the extra night and using one more PTO day."
Pros: "Seat was good"
Cons: "Crew was rude"
Pros: "Flight attendants were great, friendly, courteous and responsive. The relaxation and mediation program was great! Boarding was fluent and easy."
Cons: "No matter what you try to order on the airplane is totally disgusting. If it's not overloaded with cheese and tomato sauce then it's overcompensated with spices (salt or chili). I will never understand why it is so hard to provide simple, fresh and enjoyable meals. Chairs in economy are rarely cleaned up and one can see on the cushions that they are worn out and have lost their padding making the seats very uncomfortable. There was no foot rest available (which is such a simple addition that helps a lot) and the "holder pocket" on the seat in front was a simple net completely useless. Tables were dirty suggesting they were never cleaned and disinfected. Knowing that the highest source of viruses are the tray tables and the pockets in front I would expect attention to be focused on those- it not only impacts the health of the traveler but more important that of the crew. Why is it so hard to think of this business two fold: make revenue but mostly be kind to humans."
Pros: "Lufthansa service is always incredible. Food is better than most other carriers and so is entertainment. Had a delay due to incoming flights, but staff made sure we had plenty of water and snacks while on the tarmac."
Pros: "we arrived early. the headrests are well-designed- all headrests on all flights should be like this."
Cons: "when we first boarded and went to use the restroom before the flight departed, the floor was sticky and smelled strongly of urine. had they even cleaned it on the turnaround? doubtul. several other toilets also smelled like urine early in the flght. the touch-screen on the entertainment interface is not very user friendly and was kind of frustrating."
Pros: "Everything else"
Cons: "Boarding was even more chaotic. No clear signs for premium economy."
Cons: "The crew didn't seem quite ready for offering refreshments, and I had to go and ask for water several times. The snacks weren't very ubstantial, and having a good 4-5 hours in between meals was hard for me as I had been traveling for a long time already."
Pros: "Great Crew excellent service"
Cons: "Row seats not comfortable"
Pros: "Easy boarding"
Cons: "Could update movie selection"
Pros: "Staff was very attentive and friendly."
Cons: "Seating very cramped for a tall person. Tight squeeze!"
Pros: "Excellent, helpful steward."
Pros: "Overall it was a great experience."
Cons: "Very long flight. Try to get as much sleep as possible."
Pros: "keep going"
Cons: "Boarding was delayed by 30 minutes but they did not inform us of the delay so everyone stood in line the entire time."
Cons: "seat did not recline at all,"
Cons: "Delated and boarding was a mess"
Cons: "This long haul flight was on an Airbus plane with five restrooms in the basement. There was not enough space to accommodate people waiting in the basement so people had to stand on stairs or by the galley. Flight attendants kept on telling people not to do so but there was simply not enough space."
Pros: "The services, movie selection and food"
Pros: "Clean space, friendly crew"
Pros: "All"
Pros: "Friendly staff"
Cons: "In seat entertainment, better food."
Cons: "I did not like the surprise of having to pay for a seat reservation, once I had purchased my tickets. This was costly and certainly unexpected."
Pros: "Spacious seats Food Check-In"
Cons: "This was one of the most uncomfortable flights I've ever been on. The extra cushion attached to the chairs behind our heads made the chairs very uncomfortable pushing our heads too far forward. Not only was it difficult to sleep, it ended up giving me a terrible back and neck ache. The flight from Dubrovnik to Munich didn't have this extra cushion but the flight from Munich to San Francisco did. It's a terrible feature and should be removed. Lastly, the food on this flight was awful and it made me sick. I traveled in Croatia and Montenegro for 2 weeks and didn't get sick once but I got sick from the airline food on the way home, that's pretty disgusting."
Cons: "The seats are very uncomfortable."
Pros: "Food was terrible"

Pros: "Everything was good except late departure"

Pros: "WE HAD A VERY PLEASANT FLIGHT, MY SISTER AND I ARE BOTH IN "EIGHTIES" AND WE WERE GIVEN THE SEATS RIGHT AT THE BACK. THAT WAS THE ONLY FLAW."
Pros: "Cabin was clean and got seats I wanted."
Cons: "The entertainment system failed so no movies or any media entire flight"
Pros: "Super nice crew!"
Cons: "Inaudible boarding"
Pros: "Boarded on time. Left on time. Arrived earlier than estimated. Excellent flight crew service."
Cons: "The staff is always hit or miss"
Cons: "not even peanuts included on a 6h flight is remarkable"
Pros: "The food I purchased was good (salad, cashews, and a glass of wine)...water was offered several times during the flight"
Cons: "Cabin was hot, the passenger air controls did nothing to cool us, the staff kept the cabin lights on full, so it was difficult to nap or watch the movies/tv....the sound quality of the movie/tv is awful. My travel companion became ill during the flight (nausea, minor seizure, dizziness, hot, etc...), she did not consume any alcohol...she is 57, not old by any means ."sick bags" were not in the seat pocket, the crew barely got her one in time.....they did have her sit in the back of the plane, where it was cooler. It might have been a good idea to give her oxygen...upon landing, we were told that there would be a wheelchair at the gate (never appeared), and while we were waiting for it, the crew ignored us, only concerning themselves with the location of the nearest Starbucks in the terminal, then left us with a staff member who had no idea about the wheelchair, didn't give us any sort of ice pack. ....we finally just gave up and slowly and carefully walked to baggage claim"
Cons: "Food can be much better and entertainment options as well."
Pros: "on time, boarded quickly"
Pros: "Cabin crew were really nice."
Cons: "The media selection was minimal."
Pros: "Was not delayed"
Cons: "There was little seating space. I was unable to fully recline back because the person sitting behind me was too tall. Also had broken/uneven food tray."
Pros: "Entertainment and Food on Board was better than US carriers. Campbell Soup, Chicken Noodle Soup was not hot enough and not enough broth, Cheese was ok."
Cons: "We had yet another weather delay. Why put us on the Aiplane just to sit on the runway, Ground Stiop! The Custom process is not well explained and takes far too long. Very Bad! Because of all the delays for weather and a tight connection at Toronto we lost our Luggage. One day later at 11:00 pm we finally have our luggage. Bad!"
Pros: "The pilot set an expectation of an early arrival (30 min) that was not met."
Cons: "No free meal on 6 hours flight, small plane, chanel gates..."
Pros: "The fact that the plane landed safely"
Cons: "The service was horrible. They kept changing boarding gates on us. Luggage didn't arrive. A little delay. The service was poor as well"
Pros: "Great airline. Highly recommend them"
Pros: "Arrived safely and on time."
Cons: "Cabin crew seemed too much like salespersons. Aircraft was overly air conditioned but blankets were available only by purchase"
Pros: "In flight entertainment is great."
Cons: "No snacks."
Pros: "Boarding was quick and easy. I pretty much slept the whole way, so I can't tell you much about the crew or anything else."
Cons: "The movies and shows were great, but the machine was super slow. I also had to hold my headphones only halfway into the jack or else it would not work properly. It also was surprising to hear that headphones and blankets were extra. The plane was pretty cold, and paying for these extra fees for a family of 3 (or more for others) really adds up! Our family had two check-in bags, and rather than being charged $25 each, we were charged $25+$35 even though the bags were in two different family member names."
Pros: "Clearing customs in Canada"
Cons: "Over priced food"
Pros: "solid landing, on time departure"
Cons: "Old plane, with signs of wear. Food for purchase only. When did Air Canada take on this US business model?"
Pros: "comfortable seats good movies"
Cons: "no food for a 5 hour flight, not even snacks very crowded - not enough room for carry ons the customs procedure took forever, very nerve racking"
Pros: "Standard plane conditions."
Cons: "Flight was two hours delayed. Plane downgraded. Seat reassigned without notice. But worst was the gate agent who took my carry on because the bins were "absolutely 100% full." When I got on there were at least 8 spots for bags right around my seat. Some customers after me still had their bags. And I had to wait an extra 30 minutes at the baggage claim waiting. When I asked the lead flight attendant to get the name of the gate agent before we left she said she would do her best but then forgot. She also tried to defend the gate agent by explaining the flight was full and why I should have been glad they took my bag."
Pros: "The seat was relatively spacious, especially compared to United. Staff was friendlier too."
Cons: "Too many announcements"
Pros: "I enjoyed the pleasant crew and the constant water being given."
Cons: "The crew was very pleasant and helpful. However it was unexpected that no food would be provided on a 5 hour flight. If not a small meal then a snack was expected. The crew did provide water consistently which was very nice. My personal entertainment screen was very unresponsive and then the head phone jack wasn't working for sound, I had to hold it at a certain angle to hear bits of sound. Since the head phone jack was located at my thigh it was very uncomfortable and when I shifted I broke my headphones :("
Pros: "Asian flavored snack mix was way better than stale peanuts. Check in, gate, and attendant staff were A+."
