I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

I don't understand the concept of paying to get your personal luggage onboard and then asked to check it in.... either sell the space or don't, its a hassle to carry those all through the airport just to make a check in at the last minute.

The food was great and the service and attitude was amazing!!

It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.

Old airplanes small seats expensive tickets, not as expected overall and not comfortable according to the price

It was an OK flight with below mediocre service by their flight attendants

Wasted a lot of time trying to find the CDG lounge - it was not next to the connecting flight gate like the Air France staff said.

The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.

Much better than the major US Carriers especially in Biz Class.

I wish that the meal included a vegetable or even a salad instead of couscous! Why serve chicken with rice AND couscous? Service was good overall though a bit lacking in friendliness. Usually on air france I've been offered a glass of champagne before dinner, wine with dinner, and a digestif after dinner. We were only offered wine this time!

what would have been better would have been that my booking not been canceled by the system and had I been informed that the booking had been cancelled by the system I could have immediately rebooked and not found out that there was an issue when I was told by the system that I needed to book in. It would have also been good if either the booking agent or BA or anyone been in anyway useful. In the end I had to rebook a flight at an additional cost of $350. So no I'm not impressed by BA any of the other parties involved.

Boarding was poor. Why are first class passengers not boarded first?! Bus to the plane and then held on a packed bus because we were waiting for people on the bus before to finish boarding. Seat belt on the fist clas seat is very uncomfortable, cutting into your neck. Other than that crew, seating and food were all excellent. Entertainment, as usual - rubbish.

I paid for full WIFI- it was terrible, kept being in and out could not listen to a podcast

Flight was delayed but my previous flight was as well so It worked to my advantage. This was my first time in first class. I don't think they ever stopped feeding us. The seating area was very spacious and comfortable. The attendants were wonderful, warm, friendly and very personable.

Some how my flight was canceled, neither BA or Justfly.com accepted responsibility. I only found out about this the day before when I tried to check in. I had to book another flight which due to the time ( day before) cost me $300 more. I was still receiving notifications about the flight even when I was on another flight from you. So no my flight to London was not good.

We had a pretty good experience. Enjoyed both the flights. Crew was very good and helpful.

They issued seat assignments and sat my 2 year-old in the row behind me, separate from me and my daughter. Communication/ customer service was terrible. They told me to change it in London, then in London, they told me to talk to the cabin crew, then a supervisor came and stuck us in the back of the plane when we were supposed to be in row 25. Overall, they need to really work on their customer service. Additionally the food was terrible and they ran out of meals and didn’t have any kid options. To top it off there was no in-flight entertainment for the first hour of the trip.

We missed the connection because we had to wait for a shuttle from the plane to the Terminal. Also, we needed assistance and none was available.

When we arrived at the airport - 1st step - printing out your boarding pass - no issue. Not long lines as these machines. 2nd step - processing your bag drop off. There was only one associate there to help 10 kiosks. We had a family in front of us for 20 minutes trying to work on the machine and figure out every step for 4 pieces of luggage. My husband alerted the associate who was able to assist the family. Highly suggest that there are more associates to assist in this process. Besides this issue, security check went very quickly. Our flight was direct to Philadelphia. We had to carry our bags down two flights of steps, then out to the tarmac to a bus, then carry our bags up two flights of stairs to the plane. No one on the flight was expecting that long trek. I could see some people were struggling a bit. All in all - great flight crew, plane was clean and food was great!

There were no gluten-free vegan options available, so food was very limited on this flight, and some of the crew weren’t especially helpful about it. To make matters worse, a passenger was sick on board, and although the area was cleaned, the smell lingered for the rest of the journey. On top of that, we ended up circling for an extra hour, which only made the unpleasant situation drag on even longer.

It was extremely difficult to upgrade my partners flight over the Internet from economy to economy, plus. Then it said clearly the checked luggage can be 32 kg. At the check-in counter in Hamburg, we had to pay 100 Euros ( $122.17) for the only 31kg peace checked luggage. We were told because the change was made less than 24 hours before the flight , the luggage weight would not be upgraded. Then they offered me that for €90 I can upgrade at the counter from economy to economy, plus so we can sit together on the flight from Frankfurt to San Francisco. I happily agreed and was charged. €99.($120.95), which I noticed too late. Especially about the Euro 100 up charge I feel upset and it’s a unfair way of doing business!

Take off was not good, too hot inside the plane and seats are beyond uncomfortable.

The company said that it was Condor's responsibility to issue my train ticket, and that I should contact them. But when I did, condor said I have to contact the train company and show them my booking number. I went to the station to board my train and they said where is my bar code ticket. It was a disaster and the people at the train station said how messed up this is and that condor is the worst for putting people through this. I boarded the train with NO ticket cause no one can issue me one even though I paid and it is in my booking confirmation.

Helpful crew in a comfortable and well designed aircraft. My kids also loved the striped design of the airplane.

The return flight, the food was better. Didn't like that even at checkin we still had to pay when only 5 seats were available. Had to pay or would be stuck in the very middle between two others. I had to pay for an aisle and a middle seat. Both were considered prime seats but the two other middle ones were not.

There was one flight attendant who was exceptionally rude about the fact that they didn’t have any meatless options left when I told her I was a vegetarian. The boarding process was a bit disorganized and unclear but everything else was very good.

Seats are not comfortable. Some of the food was good and some not so good.

Really, nothing. I flew economy, and received a very good economy experience.

Flight attendants were polite but not attentive. They did not clean cabin throughout trip, and the airplane upon disembarking looked disastrous! Garbage everywhere ! The state of the cabin did NOT leave passenger with a ‘cared-for’ feeling. It looked a total mess. They also closed themselves off in the back of the plane and passengers felt like they needed to knock to get a glass of water. Very dissppointing.

Seats were not comfortable, and the problems started when we landed at Frankfurt airport. We waited more than 3 hours to collect our luggage, as a result we missed the connected train to Brussels. Our plans for the trip were ruined that day.
