Airline reviews

Hated every minute of it. This flight should have only taken 1.5hrs but was delayed over 10hours. Now I am being told I cannot be compensated or refunded my ticket price or extra leg room, which I purchased but did not receive, because the airline is throwing the blame on the 3rd party I purchased tickets through and 3rd party putting the blame on airline. No one wants to help. They received their money and that's all they care about. Im going on 3 days of still trying to get to my final destination, had to cancel car rental, car insurance and hotel. Currently staying in airport until hotels open up. Thank you Lufthansa, Kayak, Underpricer and United for making this trip the worst ever.

the flight from Tampa departed with a delay. The food on board was poor, usually on international airlines alcoholic beverages are offered free of charge , but here it was for a fee, the cutlery was wooden, there were no hot drinks (tea, coffee). Unfortunately, I didn't take pictures of the portions of food, but it wouldn't have been enough for a child either.And in the future, I will try not to use the services of this airline

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

Positive: Entertainment via phone on the short was great and my first time. Good food and wine and head phones for free. Negative: Seat hardly reclined on the long flight. Breakfast was an egg with a bun. No egg choices and rather have something sweet like bun/jam and Youghurt.

Flight from CLT to DUS via MUC ticketed by United Airlines and operated by Lufthansa. 2nd leg of flight from MUC to DUS was cancelled and no notification provided. At check in , Lufthansa agents at airport were unable to locate record and wanted us to contact United Airlines directly.

Boarding went well, staff was friendly. Food was not goods at all. I had ordered vegan meal. The seat I picked didn’t have storage area in the front and so had to put my small back pack at the top.my flight to Bangalore from Munich, the tv was broken so I got complimentary wifi which never worked. Food there too wasn’t good. I had paid extra for the seats. The only good thing is that the fact we have a flight direct from Charlotte to Bangalore with one stop in Munich!

By in large it was a good experience. The flight crew was great and that's the most important to me. Boarding was fine.

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

I really enjoyed the staff and crew! Very positive and happy people! Made the experience easier! The entertainment was a bit lack luster. Better movie options as well as equipment that works smoother could be nice. My ear buds from the airline didn’t work and my tv screen had a terrible delay that made it hard to search for things to watch. Also the selections were very limited.

Every experience was good except for the lack of comfort in those economy seats. I never had knee pain until that flight. Those seats are uncomfortable.

Very nice flight, easy connections in Keflavík, and friendly crew.

I will never fly this airline again. Checking in was poor , we had to go back to the check in counter at Raleigh - Durham international airport three times because they didn’t issue my boarding pass but rather duplicated my husband’s twice which caused a big headache at the passport control at the airport which triggered security alert and wouldn’t let us pass through we we had to wait for long time to be able to explain and clear everything after talking to the supervisor.. No food on the plane , not even crackers. No food was offered to buy ether . No ear phone was provided . Very little time to make from one plane to another and nobody to assist with smooth transition. Flight itself , we felt safe so thank you to the pilots . But customer service was terrible . We spent $ 2500 on 2 tickets, so I cannot say that service was consistent with the price .

Seats are way too much now with these new airplanes especially long flights like we had. I was 7 month pregnant and in a lot of discomfort due to small seats.

Food was horrible. This wasn’t business class. No leg space, can’t sleep in row position, huge delay

I liked how easy my transfers between flights in Keflavik were. I would have appreciated more food options in Keflavik.

The plane was flaming hot! Could not breathe. Everyone coughing from heat. Awful.

My biggest problem was the flight from KEF to DUB was delayed, which caused me to miss my connecting flight in DUB and we were forced into an unplanned 10-hour layover in DUB. Crew and boarding staff were all very friendly but this was a real inconvenience and especially uncomfortable for my disabled wife.

Not much! This was my first flight with Iceland air and unfortunately it wasn’t what I have expected. My luggage is lost nothing as of yet where it was left. Not a good service at all!!

The seat size was more like a domestic than an international flight. In fact, i would compare the ammenities, quality and service to a short hall ryan air flight, which was unexpected for an international flight. The plane was extremely hot so sleeping was difficult. My biggest complaint was that they are very strict on carry on luggage only allowing it to weigh 10kg/22lb. I try to limit myself to a carryon so i don't have to mess with bagage claim, but the wieght restriction made it impossible. I have never had a carry on weight restriction (at least enforced) on an international flight. Will not be including them in future searches.

Pros: "I liked the northern lights look after boarding upon introduction of the captain and crew members. Everyone was super personal and uninformed looked great. The best part was when they started boarding from the last row, which is the most logical and efficient way to do it"

The food wasn’t great and it would be nice if the airlines showed documentaries about the countries we are flying into.

Disappointed everytime. The app doesn't load the boarding passes. They have lots of agent that seem to be busy doing nothing with a long line waiting to get paper boarding passes. Food choices are poor. Entertainment is less than entertaining.

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 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.

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

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.

Excellent! Great flight attendants, good food (in business class, at least), very comfortable. Touchscreen and remote wasn’t great.

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

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.

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.

I don't believe we were given any food... but for the size of the plane, it was pretty comfortable and a nice flight. I dont believe there was any individual onboard entertainment, and the headphone jack was the one with 2 holes, so I couldnt use my headphones... the boarding times were all over the place, and we never really flew on time.
