Horrible experience. They "GAME" with seats they decided to play where you can`t select or get seat during check-in without paying and then forcing you to stay long line at the Customer Service at the gate to get a boarding ticket with seat assigned is pathetic. Will never fly with United again!

Horrible experience. They "GAME" with seats they decided to play where you can`t select or get seat during check-in without paying and then forcing you to stay long line at the Customer Service at the gate to get a boarding ticket with seat assigned is pathetic. Will never fly with United again!

So terrible. They would not rebook me for a flight until 2 days. I had to spend so much money to get my own flight. They were rude and not helpful.

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.

Bag lost. Lost bag recovery process is an unsatisfying customer experience. Because 1) bag is still lost but also 2) the process is outdated and form-heavy and 3) in our case also involved a long line.

We were very impressed with Swiss Air. The service was exceptional. Unfortunately, we had a baby behind us that screamed for hours. , It was a nightmare, though I completely understand that it was not Swiss Airs fault.

We had to move to terminal 5 for the next part of our trip. Very un-organized and difficult.

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

Cons: "Flight was completely full and certain passengers were belligerent about wearing face masks. The cabin crew did not enforce mask wearing, stating “we are not the police”"
Pros: "Nothing. There was no flight. The flight was cancelled and you did not notify us. We found it out ourselves by accident. We tried to contact you guys but we could not call or anything other. You guys suck"
Cons: "Notify your customers when the flight is cancelled. Thats the least you can do. Very unprofessional"
Cons: "I fell sick and my doctor advised against flying. Tried calling Swiss Air and JustFly.com: 6 calls back and forth and 7 hours on hold, no help. Finally got advised on driving to the airport to make the flight change at the Swiss Air counter at O’Hare. The representative told me to bring a note from doctor to switch flights. I did the next day. The same representative looked me in the eye after advising the day before and said there’s nothing she could do. Why make an elderly sick person drive to the airport again if you know already you cannot help??Absolutely terrible experience, no help from the airline or travel agency. Total loss of the full price of the ticket."

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!

All good! But sandwiches for breakfast need to be warm!!!!! Not cold!!! You do not want anything cold in your stomach in the morning!… think about it!

The staff was good. Very friendly and respectful. The airline not so much. They aren't very informative at all.

LOT airlines wasn't the best. They had trouble with boarding and they didn't have my information on file the right way. They change last minute details without us knowing and everything was a HOT MESS. Lot airlines also lost my baggae which was the carseat and haven't responded to any of my emails.

Lost my suitcase. And communication was poor. No offers of compensation for over 24 hour delay of bag

Would have liked to have Wi-Fi on the longer flight (nyc-Warsaw)

My flight was cancelled and I went through hell to get it fixed, with no help from the website I booked it on. My reservation was cancelled AGAIN by the site I booked on without my knowledge a week later. The flight itself that I finally got on was awful. Drunk man belligerent the entire flight, I don't understand how he was allowed on the flight.

Lot still has not refunded me after they cancelled my flight to India!! Kayak had been awful at getting me this refund too. Will NEVER be using kayak or LOT again.

Tv screen not working. Food in business class was cold & not available

The customer service and the flight experience were very good!

My bag was lost despite an almost 8 hour layover in Warsaw. Nearly 12 hours after my arrival, I have not heard anything about 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 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

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.
