Seats are fair enough for medium tall people. Good food all the trip. Fight attendances are warm

Seats are fair enough for medium tall people. Good food all the trip. Fight attendances are warm

no issues at all... Kudos to the food. This time was really really good

The food was ok. The crew seemed like they were cranky. I had one guy get mad at me for passing in between the storage area to get to the other toilet. I can understand if it's not allowed but reprimanding me like I'm a student saying "This is the last time!" was not appropriate. During my meal time, there was a French family around me. No problems there but when we usually have meals, they are supposed to put their chair in the upright position. These people did not do it and the steward did not tell them to raise their seat in the upright position. However, I was told to do so! So, me and another person next to me had to eat with the monitor almost touching our faces. Furthermore, a lady in front of me was putting her feet up and preventing another elder passenger from putting her seat back. To make it worse, she was continuously hitting her back into her seat, shaking my monitor while I was watching a movie. A crew member did speak to her about it but then she accused me of pushing her seat forward! The crew member gave me a death stare and told me to stop pushing the seat forward. I did not even touch her seat at all, if I did, she would know it. Her boyfriend also stood up and tried to push her seat even further past the maximum decline to no avail. None of these people were reprimanded but the steward, some bald guy, was extremely friendly with them and did not even try to instruct them to do anything until it was time to land. I resisted the urge to really argue with them because I would have obviously been seen as the aggressor (I have no idea why). I hardly said anything on this flight except "more wine please" and "sorry" if I bumped into someone accidentally. Overall, it was an annoying flight and I had to resist the urge to yell at the steward and the people he was overly friendly with. The happiest moment of this flight was leaving it.

The worst airline. Cancelled flight 30 min before boarding and rebooked on flight after 3 days.

It was nice to be on a legacy airline, people try at least.

I requested wheel chair assistance , it was confirmed via email that inwoood get it but I didn’t get it . The last leg of my trip to Nigeria was the worst.

The boarding was one of the worst I’ve ever experienced. The fault lays on Ohare Airport and not so much the airline. The waiting area by the gate was the size to accommodate a regional flight for 20-30 people and right next to a busy walkway. When you cramped nearly 300 passengers into that space is was unbearable.

one of my bags was drenched with fish smelling water and all my new clothes bought at dublin and the 23kg checked in bag were all gone waste with very pungent fish smell and also having stains

Seats actually fit a human! Snack options were a bit lame but that’s ok

Pros: "Crew was great, on time flight, clean plane."
Cons: "Entertainments options were shockingly few. Honestly have not been on a plane recently with so few and limited options of TV series and movies. I was extremely surprised. Wish I had know and I would’ve had more options for my family."

Super friendly crew. Leg space and entertainment system are below average

The plane was so hot upon boarding. Their boarding process was so unnecessarily long. Service was subpar.

I guess just the food, but besides, amazing experience flying with swiss

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.

They went out of their way. It was very clean and friendly.

Wheelchair was the excellent service. I didn’t have any food or used entertainment. Overall for my trip experience was excellent. Thank you very much and keep up good work. Best regards

Motivated and friendly crew on a somewhat dated but well kept plane. Hd seats in economy may section, so legroom was excellent.

We so appreciated that our connecting flight waited for 6 of us!!!

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

Pros: "The crew was super friendly and attentive. Best in flight service I have received in a long time."
Cons: "The plane doesn't have usb ports to charge the phones, and as there are no screens or anything else, make sure you bring your battery pack."

Medíocre. The food wasn't good (although not bad, bad) and the staff wasn't kind. I asked for n extra blanket, the steward never came back, serving us roughly.

Boarding was smooth and on time. The seat was comfortable and the entertainment worked. Staff were gracious.

Business class in the second leg - CDG-EVN was a disaster.

Food could have been better especially the breakfast. Overall it was a good flight

No bording was given for next trip on same carrier, food was very moderate.

We transited through Chad and what was supposed to be a 1hr 20 minutes transit time lasted over 4hrs. We didn't get regular updates until we complained. After a 10hr flight from Paris no form of refreshment given and finally arrived Abuja over 6hrs later and none of my bags came

The line at boarding was not well organized and managed

Crew was professional. Boarding has few seats . Since the plane was not full would have been nice to change seat on the internet

My seat was so uncomfortable, and the headrest was broken. Very very disappointing for the price I paid.

Even though my seat is a paid seat, I was told to give up my seat to a passenger. I tried to ask the CA to negotiate, and when I spoke in Japanese, the CA fled. I had to find a Japanese CA and ask them to deal with it. . After takeoff, I spilled my coffee, and when I asked the flight attendant for a towel, she told me to wipe it off with a wet tissue. My clothes got wet, so I asked CA for an extra blanket, but I had to wait for an hour.

It was a nightmare. I booked business class ticket from Ediburgh to Beirut via Istanbul to attend a funeral. I had a wonderful experience flying to Istanbul from Edinburgh. Then I could not get a boarding pass issued to Beirut. It seems that although they booked me and I had a reservation number, I had no seat allocated and the flight was full. I was asked to go from one desk to another and made to wait for 2 hours. I missed my flight as I did not have a seat assigned and it was full. The only option was to put me on the next flight, 6 hours later, for a fee of over $400. They said that was the best they can do to 'help me' and to 'take it or leave it'. Well, I was not about to be bullied; I stood my ground. I booked and paid premium for the journey, which was confirmed. The eventually accepted to not charge me extra and i waited a total of over 8 hours in the airport with no compensation. On top of my grief with the risk of missing the funeral service, I had to put up with their indifference and condescending attitude. They spoke about me in Turkish thinking I would not understand (I hold a British passport) in front of me. When they eventually handed my passport and boarding pass back to me, I showed them I was born in Istanbul and that I understood everything and said a condescending 'thank you' back to them in Turkish. You should have seen their faces. I said that consumers have rights and it is a shame that Turkish Airlines does not have good customer service to at least acknowledge and apologize for errors committed by the airline. Blaming the me, the client, for such an error and placing unreasonable ultimatums, rudeness and dismissiveness to be rid of me, particularly when I was vulnerable and visibly grieving was really shocking... The airline taints the city of Istanbul and the people of Türkiye. Such a shame.

3 of us were in the business class. All good except the Flight out of Mumbai is too early. It is at 6:30 am. Reporting is at 4 am. We had to get up at 3 am. US connection has 4-5 hours of layover. It would be nicer to start the India flight late (give more time to sleep at home) and have less layover duration in IST.

The flight departed on time and the staff was professional.

The airplane from IAD to Istanbul was too old. The chairs were to tight and uncomfortable. I continued my travel from Istanbul to Bangkok. This airplane was better and newer than the first one. Even food was better.

Process for on line checking needs a lot of improvement. Very frustrating.

The crew was excellent, but the flight was a little delayed and the temperature on the plane was too warm.

the female flight attendant was racist towards me. I could tell she treated the two other passengers next to me with more softness.

Friendly crew. Computer systems had trouble keeping my Star Alliance status linked to my reservation. Inflight Wi-Fi was slow and expensive. No standard power outlet, but medium-power USB-C port slowly charged my laptop. No option to buy whisky in economy.

It was a terrible airline. The air hostess and the people in the flight, just very rude.

I canceled this flight after turkish airlines did not provide any consideration for a death in the family while in Singapore

The business class seat is the same as economy with 2 people instead of 3. That's not how it should be.

It was freezing in the airplane. Everyone was wearing everything they had with them. The crew acknowledged it was cold, but did nothing about it

The most horrific experience we had with the airline that we had in our life Everything was substandard at best. For just one hot tea they charged 4 euros We paid for Lufthansa months in advance ,to get there they didn’t have us in record and after 4 and a half hours layover we almost we got one seat at the first row and one in the back of the plane On top of that our suitcase was seriously damaged and it’s unusable. Here we are halfway around the world in foreign language having to fix this on our vacation time Would you kindly and quickly resolve this matter

Horrible experience. Nothing to give to kids to keep them entertained.

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

Checking in could not be done in the UK for this prt of the flight . Since we only had an hour and a bit at Singapore it was very stressful not knowing if we had appropriate seats. The flight itself was Ok and the 787 had a bit more legroom than the777 from Munich to Singapore. Food wasn't great.

Prompt boarding, safe landing and they didn't lose our luggage. No entertainment and no USB plugs to charge phones. No food, though I might have been asleep.

My school age daughter was not sat near me. We left almost an hour late. Therefore arriving late and missing another flight. Since it was not a connecting flight there was nothing Lufthansa could do about it. After the selay in take off and arrival we waited almost an hour for baggage claim. There was zero concern for my inconvenience. I asked if we could insure being seated together on the return. They stated no because we booked through Kayak. I typically love Lufthansa. This was very disappointing.

Didn't have bar code on our phone based boarding pass. People at the counter didn't notice. We walked to security, couldn't get through, had to go back to check in to get a paper boarding pass.

It was timely boarding, well organized. The food was weird in a flight to Buenos Aires. I felt as if I were flying to Asia because of the chicken teriyaki. In my section flight attendants spoke only German and English. I wondered why no Spanish speaker was hired for a flight to Latam. In that Lufthansa needs to be more customer oriented. Compared to other airlines the four seat in the middle is less comfortable. That said, staff was polite and efficient, the entertainment system worked well. It was ultimately a peaceful, well organized and safe flight. Thank you !
