Overnight flight in the old style Business class, but still very good.

Overnight flight in the old style Business class, but still very good.

I was in business class, without the business class amenities. Large seat with lots of legroom, but no TV or bed. Food was okay, but I did enjoy the Turkish red wine.

Excellent service and comfort from the moment you check in. Flight crew is hyper focused on making passengers comfortable and at ease. It’s like a flying hotel!

Only chicken as a meat dish through out the flight

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.

Flighty delayed on boarding - then group 1 had to check their carry on bags but groups 3 and beyond could carry bags on - very inconvenient for weekend business trip with no checked baggage. Then delayed on the runway - before take off. No communication from pilot on why or how long. Wifi/Entertainment didn't work for 4+ flight. Upon arrival, attendants announced wrong carousel for baggage claim - everyone was waiting at the wrong place for their checked bags. This was a mess united!

I flew Delta last week and United Airlines is a poor substitute mechanical problems with the plane and shitty food among other things made my travel experience what’s become to be expected from United no way is it ever worth the money they make us pay

I had a great flight. Everything went smoothly and the flight arrived early.

Well....let's start from the point that I had to stay in airport for 12 hours instead of 2 that was scheduled. Poor company and even worst customer service. Never again....

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

We liked the fully reclinable seats. Had center seats, so it was difficult to talk to spouse. Crew was great

Aisle chair was good and liked the foot bar preventing you from putting your foot in the isle, The breakfast on this international flight to Zurich was horrible (Europeans, specially, used to good food) may make this a dealbreaker for booking with United Airlines again. I agreed with my Spanish fellow passenger.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

The Wi-Fi was unavailable on this flight for some reason.

Poor, we had 1 hour to grab our checked luggage, go through customs, recheck bags and run across terminals to make our United flight. Poorly planned connections.

Check in in Albuquerque was awful. The people were great but they were over loaded. The procedures were terrible. We got through fine but it took 90+ minutes.

Will try to not fly with them again. Delays because of weather but got redirected to an airport where I could not make connection.

Staff didn’t care in business class. Closed the door on my mom while she was on the jetbridge and flight attendant told me she would make it from the connecting flight. They lied. My luggage was damaged on arrival. No success in filing damage claim.

Boston Logan is a crummy airport - signage is terrible or lacking in areas. Boarding seemed to be a free for all and with all the different airlines speaking, you couldn't tell who was supposed to be where and when. Plain and simple, airlines should board from the back of the plane to the front. Also someone was sitting in my seat. By the time that was figured out, I had to place my overhead behind me which made de-planing more difficult. Logan is not Lufthansa's fault so that is not on them, Boarding is on them! Still, overall it was a Good Experience flying with Lufthansa. This is not my first flight with them...

Overall, the flight was comfortable without any serious issues. Transit through Frankfurt airport was a little confusing, but not too difficult if you follow the signs

There was a screaming child behind our seats. This prevented us from getting any sleep during the night.

There was a screaming child just behind our seats. This prevented us from getting any sleep during the night!!

Staff disappeared after dinner service until breakfast, no help with beds, no help running to our gate to catch connection cause flight was late, our luggage didn’t make it, took over 24 hours to get luggage to hotel, no compensation!!

Everything was good except food. I believe there is room for improvement

Boarding was as fast and efficient as possible. The flight crew were amazing and extremely friendly. We enjoyed our flight.

Very bed boarding, there was overbooked and make a lot of problems and noises

There was a problem in the luggage because there were not porters

On my way from Chicago to London, I was seated next to a quite heavy passenger. I could barely move. BA should have ensured that overweight customers are placed in comfortable seats and not to penalize also other passengers because BA is not willing to accommodate these passengers and their needs. No respect at all.

The flight as far as timings go was excellent. Unfortunately we ended up sat with someone on a night flight who had been drinking alcohol before boarding and BA staff were happily serving him more alcohol. He was very drunk which made our flight uncomfortable and awkward. My partner had this person lying on him whilst asleep. Alcohol should be served minimally. If there had been an emergency this person would not have been in a fit state to act accordingly.

First time flying with BA and I will do it again. Staff at airport and on board were very nice and helpful

they are improving. The crew from Charlotte to Tampa was outstanding. SMILING and trying to be helpful with the customers.

Wonderful service and very comfy in the bulkhead in Economy Plus! Delicious food.

The BA team at Sky Harbor is deplorable, full of unnecessary attitude and poor communication. It seems like every member of the team was looking at another to solve the problem, instead of taking agency to do so themselves. I saw no less than 6 altercations with the same gate agent where he threatened to revoke the passengers boarding pass for asking a wildly reasonable question, something as simple as where the cue to board was. I’ve complained to BA before but it seems this isn’t an issue for them, which is very disappointing

Boarding poor in London,ok in Chicago. Don’t like Heatrow/terminal5

Boarding was delayed and a bit hectic. The crew was super nice.

Brand new airplane Airbus 330. Great crew. The staff on the ground is always a bit mediocre at Condor.

Some pretty unfriendly check in crew members. This is a no frills airline.

Seat was the worst I ever had in an airplane

I will definitely recommend your service. This is my first experience with Condor and so far it was great!

A flight attendant placed a meal on my tray. I was in 44E. The passenger who was in 44G had gone to the bathroom. I ate the meal. When the passenger in 44G asked where his meal was the flight attendant put the blame on me. She claimed another attendant put the meal on my tray. She then claimed when she gave me the meal she asked me if I had ordered a special meal. She did not Worst experience I have ever had with a crew member.

Entertainment screen was not functioning, there was no effort made by flight attendants to take care of the problem. All I could do was looking at customs forms and watch landing videos for 10 hrs 😁 Bruno Volk

I did not get a flight from JFK to Portland nonexistent Condor flight 308 does not exist and JetBlue knew nothing and someone changed my ticket and eliminated that leg of the flight. I would love to know who’s going to pay for my $750 car rental.

My return flight from JFK to Portland Maine disappeared and it cost me $750 to rent a car and drive home from New York. I don’t even know where to start with who screwed up or what condor blaming the ticket sales or JetBlue JetBlue knows nothing. Everyone giving me the runaround. Gotta say the service all-around sucked.

The flight was fine. We were served a meal and a snack. Boarding was fine.
