Seat back monitors and outlets were dead and not working.

8.0 ExcellentCarl, Apr 2024JFK - FLL

Seat back monitors and outlets were dead and not working.

Everything was great except for the seat. The backrest would not stay in the upright position.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

Flight delayed about 2 hrs so it made it a VERY late night

The crew, food, and entertainment were all good. But my screen had some sort of bug where if I turned it off, it would turn back on after 2-5 minutes. At full brightness. It made it very hard to get any shut-eye on the overnight flight. Also, the older Boeing plane, while nicely cared for (and no doors fell off 😅👏) doesn't have the nice air quality of newer planes. So I felt a bit greasy by the time we landed in Sweden.

It was a crowded flight. They did the best they could.

Service was good for such a short flight. Small plane but smooth flight.

Worst flight in my life. Only was scheduled for a 45 min flight to get our connection flight. It was late by 40 minutes and we missed our connection. Delta was totally useless trying to help and unable to get my family on the next flight because they overbooked it Thus had to get a hotel at my expense and lost a day at Disney as a result. Cost me about a $1000 if you add 2 hotels meals shuttles etc to get thru the day Awful customer service by Delta in Detroit totally useless people

The experience was good and the flight departed on time and landed early

The flight was delayed but we got to our final destination.

Overall a good experience, the flight was on time, the crew very attentive and friendly. However the seats are too cramped, there is no space, and as soon as the person in front reclines the seat, it's literally in your face.

Bag lost. Lost bag recovery process is an unsatisfying customer experience. Because 1) bag is still lost but also 2) the process is outdated and form-heavy and 3) in our case also involved a long line.

We were very impressed with Swiss Air. The service was exceptional. Unfortunately, we had a baby behind us that screamed for hours. , It was a nightmare, though I completely understand that it was not Swiss Airs fault.

We had to move to terminal 5 for the next part of our trip. Very un-organized and difficult.

Missed connecting train since flight was late into Zurich and I had to stay at airport hotel because of it as well as I had to repurchase train ticket

Cons: "Flight was completely full and certain passengers were belligerent about wearing face masks. The cabin crew did not enforce mask wearing, stating “we are not the police”"
Pros: "Nothing. There was no flight. The flight was cancelled and you did not notify us. We found it out ourselves by accident. We tried to contact you guys but we could not call or anything other. You guys suck"
Cons: "Notify your customers when the flight is cancelled. Thats the least you can do. Very unprofessional"
Cons: "I fell sick and my doctor advised against flying. Tried calling Swiss Air and JustFly.com: 6 calls back and forth and 7 hours on hold, no help. Finally got advised on driving to the airport to make the flight change at the Swiss Air counter at O’Hare. The representative told me to bring a note from doctor to switch flights. I did the next day. The same representative looked me in the eye after advising the day before and said there’s nothing she could do. Why make an elderly sick person drive to the airport again if you know already you cannot help??Absolutely terrible experience, no help from the airline or travel agency. Total loss of the full price of the ticket."
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: "Entertainment"
Cons: "I requested a vegan vegetarian meal and did not get it. I had to do with the regular meal which had a lot of dairy products to which I am allergic to. The space between rows of seats. It was really crammed in Economy and we are a petite thin family!"

Good dinner and nice plane.Smootz flight. Breakfast had no sweet option. Seats hardly reclined.

Too many fees (but that seems to apply to all airlines nowadays)

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Everything was very good. Boarding and takeoff were on time and organized. Had a good flight

Wheelchair assistance was not complete. The person left me at the departure gate without informing the groundstaff of my requirements. I had to walk to the departure counter to ask for help to reach the plane door. The crew informed me that in future they were not allowed to help passengers like me, senior citizen and Wheelchair passenger with placing their carry on bags in the overhead compartments!

Flight was delayed by over an hour and gate checked bags took 15 minutes to be delivered to the jet bridge.

Seats are way too snug for my hip to knee ratio and the recline on the seat in front of me made my experience worst. My legs had no room at all. Not a plane for people 6 ft or over unless you fly first class.

Delayed for maintenance issue?? Should have been addressed before boarding. Put my bag on an earlier flight, but didn’t ask if I wanted to change to an earlier flight. Arrived to find my bag locked up and no agent to be found when I landed.

It was a great flight, great crew, excellent service, fantastic brand new place, overall 10+ on the experience! Thank you.

We learned certain countries (a few) require a notarized letter from an ex to give permission for children to travel to those countries with the other spouse together with birth certificates. To find this out one hour before flying—not good. Nowhere is it documented by the airlines though they require it. Make sure about all documentation required.

I dropped my wallet under my seat on this flight with all of my money and credit card. I requested to be able to go back and retrieve it but Lufthansa denied my request. I went to the Customer Services and they called Lost and Found but I was told nothing found would be turned in until around 12:00pm. My next flight was leaving so I was unable to check to see if my wallet was turned in. I will never fly with Lufthansa again.

My concern is with Flight: 441 IAH-FRA I was very cramped in my seat and the person in front of me was reclined. I pulled my wallet out of my purse and when finished I did my best to cram it back into my purse. Our flight was very delayed and we were rebooked twice and lots of airport time. As I got off the flight I noticed that I had dropped my wallet( containing all my credit & debit bank cards + 240 US dollars & 240 Euros. I spoke to customer service & Lost &Found. I was denied access to look on the plane. Therefore I have been without money and given no help. Paula Bjork 503.545.6698

Dinner was good by air travel standards but breakfast was too light and heavy on carbs/sugar.

Used to love Lufthansa, but Rowe are too close together in Economy and passengers are allowed to recline their seats so far back it is impossible for those behind them to even reach for carry-on essentials during flight - except for meal service when flight attendants ask for seat backs to be raised, we can’t sleep on planes so this flight was most uncomfortable ever! Rod Rose

So far so good. I missed my flight because of the Lufthansa diversion. United helped me to figure out how to get accommodations from Lufthansa for my long layover. They help me book appropriate onward flight.

Horrible crowding on the seats, headphones provided did not fit or work in the entertainment center, seriously the most uncomfortable flight I have taken in a LONG time. The people in front of me were literally 5 inches from my face the entire flight. Did they change their seats recently? I remember it being tight but wow this was a whole new level. Also I am a 5'3" small woman so I can't even imagine a larger person dealing with that for 11 hrs.

Seat controls of lights were broken, and only 1 of the 2 seat TVs ever worked on the long flight. On the short flight there were no USB connections, on the long one they were difficult to access. Part of my meal was frozen, though the hot portion was good.

Lufthansa fails at mentioning no luggage when booking through points. We had to pay added fees to take checked bags to Europe for 2 weeks. The staff at check in were not helpful at all. told us "if we don't like it, then book another flight". Food was bad, they ran out of half the options. Vegetarian was terrible. The flight crew was nice, and tried to make it work ok.

Always a pleasure to deal with United's helpful and knowledgeable staff

Always a pleasure to deal with United's helpful and knowledgeable saff

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

Terrible! I missed my flight to my final destination and British airlines and American Airlines keep pointing fingers on each other’s. Nobody wants to take responsibility

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Overall, terrific service, accommodations, and experience. Only reason comfort was rated lower was because it was difficult to keep a comfortable sleeping position for the overnight flight, but I also had an economy seat.

Not sure if the crew were experiencing something unknown to me,but the service of passing water was non-existent.In addition,please take consideration when providing yogurt as alternative for breakfast as some of us, could be lactose intolerant.. thanks

Very cramped seats in economy, difficult to get comfortable with your legs and feet and back. The seat width is ok but I’m average size. Food is HORRIBLE. Crew is friendly. Delays and very tight connections made it tough for navigating. We would have missed our connecting flight if it wasn’t delayed too. The terminal transit was slow and normally every 10 minutes before 8pm, after 8 pm is every 30 minutes!!!!! No free wine or drinks!! Below average attitude.

Leg room was better than expected. Lavatory’s were easy to access.crew was grea!

Horrible seat allocation. Boarding was slow. Food was average and so was entertainment. The TV terminal didn't work and so had to use remote.

Lost one checked bag.and wasted 30min waiting and filing missing baggage report. Very unsatisfied.

I’m not happy because I discovered there is something wrong and my miles have not been getting put on my AA account. So this needs to be fixed because I have traveled a lot since October and none of my miles are registered
