On my way home I had a layover. The flight from ATL to CLT was amended 5x while I was waiting. I could have driven home sooner. Overall from Dallas, Tx to Charlotte, NC I started my trip at 4:30pm, I didn’t get home until past midnight. I know things happen, but 5x to make me run back and forth in an airport from different terminals is excessive. I also upgraded to comfort + , I didn’t feel it was worth it. There was no benefit

They did a fine job. Can't wait to use Delta in the future.

There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

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.

Upgrade to business was great. The crew was nice. Disembarkation in Bucharest was very slow through the rear door to a bus to get to the terminal. The business lounge was not clean with bugs running on the floor.

I rated food and entertainment with the lower score because I did not have N/A. No food and entertainment from Bucharest to London.

Poor service ! Water need to be free and a little snack for 3.5 hour during the flight. Tarom company need to take lessons from Turkish Airlines.

There was extreme turbulence for 10-15 minutes a bit after takeoff, which of course is no one's fault. This was a short regional flight with no amenities except water. Departure and arrival wete close ro on-time. The Suceava airport is very small but pleasant and efficient. My baggage all the way from Washington DC, checked through Paris and Bucharest, arrived without a hitch. There was really nothing to complain about except a regrettable 5+-hour layover in Bucharest.

This experience was atypical. The flight left three hours late because of engine technical issues, which meant a very long wait. Unrealistic announcements made it worse by discoursgong leavimg for water, reatrrom, etc. But the crew did its best and apart from the delay, it was not a bad flight. Good entertainment and drink service.In the end, I made my connection anyway.

Pros: "The crew and the flight from Bucharest to Istanbul"
Cons: "The airplane from Athens to Bucharest wa terrible, very old, smelling bad, not maintained, and noisy"
Cons: "Boarding... always boarding being confuse! Tarom flights are... difficult to understand why this happens"
Pros: "Comfortable’ish seats, left on time... arrived early!"
Cons: "Boarding is, continues to be, a big issue! Not organized, everyone trying to jump ahead of others..."
Pros: "The check in was very rude and moody for no reason. He was not accommodating with the seating arrangement"
Cons: "Ask the staff not to be so moody for no reason at all."
Pros: "The crew was amazing. They answered to my requests politely and helpfully"
Cons: "Some of the plates/tables are not rigid/straight horizontal. Should be checked and readjusted"

Nothing really was great as such. Seen other no name airlines perform better.

Quality of service on board was very inconsistent. FA service primarily seemed robotic and they barely engaged with passengers

I’m unclear why I had to pay extra for assigned seats as Turkish airlines did not honor the seating. We were placed across the aisle from each other on TK 34, and were seated behind one another on TK 694. Because my name was misspelled on e-ticket (Klawiter, instead of Klawitter) I could not log onto website to get the connection gate number in Istanbul. The monitors in the airport were a jumbled mess 1/2 Arabic and 1/2 English.

On line check in needs a lot of improvement. I tried and gave up.

Food not good, flight attendants not the best, not accommodating very ruff

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

Oh my god! For an13 hour flight they serve you food just one time. Also don’t be thirsty they give you a little small cup of soda to drink. They seem like their goal is to feed you one so they don’t have to be bothered with you. It quite surprise for such a long flight there are several times to eat at least three and the food was well lackluster. The food and lack of offering drinks which were always hot no ice provided.

We were traveling first class. Checkin counter lady and her manager, both were in bad mood and did not treat us well about checking in the handbag. The gate agent took care of it right away. I travel Turkish twice a year in first class. No one has ever refused to check in the hand bag. Not sure, why this agent and her manager refused. Everything else was excellent.

The 787 economy was a disaster for long haul. The space was too little compared to 777 or 747. Also the extremely low tray table behind the seat made any dining effort a nightmare. However, the movies were up to date, and the food taste was good, despite of terrible serving process caused by small space.

A little bit more comfort. It’s tight space around the seats. But all else is great and a smooth flight!

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

I think I have bruises on my kneecaps. Do the seats have to be so close together these days? And if they are so close they really shouldn’t recline. I think when the gentleman in front of me reclined, the back of his head was on my chin. That being said the crew were always caring and polite, and the flight was on time and very safe. So I’m grateful for that.

I always try to book flights that don’t charge for baggage. Yet I was charged $75 for this flight.

Trouble keeps changing the time and I was booked different flight without knowing it was bad experience

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.

Starting with the flight Cairo to London the plain was so poor no entertainment at all uncomfortable seats although it’s 5 hours long,then an American airline plain took me from London to Miami it was a bad experience the crew most of flight time not available and they asked us to help our selves for any snacks if we need. From Miami to London actually was perfect flight with a huge plain and perfect crew but from London to Cairo was horrible plain with stiff fixed seats not movable no entertainment or wi fi very poor Menu which is unacceptable for a business class

I've done hundreds of flights in my life, and this flight was one of the best I've ever taken, From beginning to end, everything went smoothly, professionally, and with a smile and friendly attitude from all employees I interacted with. The food was delicious (and free), as were the drinks. There was just a genial and effective way in the way that British Airways organized the flight -that reminded of days in the 70's, 80's, and 90's, when flying was a fun, and exciting adventure. I enjoyed and had confidence in the abilities of the flight crew, I'll be flying British Airways several more times this summer. Thank you so much for the great experience! Cheryl Olso

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.
