The flight and all amenities were good to excellent. SWISS was awful to deal with. Every step of the way they nickel and dime you. Chose your seats? $14. Change your seats… No accounting for the prior payment. You get billed again. 17 pound restriction on overhead luggage, nonsense. It’s a weight in the plane whether it’s in the overhead or in check baggage. They just milk you for every cent they can and I resent it. The flight was excellent.

plenty of legspace, snacks, no pull face from flight attendants when asking for a wine. Also fast transfer ability at ZRH.

The flight itself was fine, but due to a snow delay my connection to Lisbon was delayed by six hours. Despite this, Swiss Air still managed to lose my luggage. Not acceptable. Someone else on the flight also lost their luggage.

Bad experience overall. Crew did not provide food for our 2 year old (even though we specifically bought a child infant seat for her and literally bought another full price flight), which was unacceptable. And we had to pay $310 each way to carry our ski equipment even though they advertise it as something that is free. Tickets were purchased the same way as usual, but they told us we had Economy Light tickets (I never elected to have such seats). Just plain manipulation and false advertisment. Very disappointed overall about this airline.

The trip was great until my luggage was lost on transfer from United to Swiss. It took Swiss 3 days to get my luggage to me though it was located almost immediately.

Horrible!! The WiFi was not working, the food was awful

We’ve never been more uncomfortable on a flight than we have on this particular one. The seats in front of us reclined so far back that when the person reclined their seat of broccoli, it almost hit me in the face and left me with literally no room to move that said I had to recline my seed in which made the person behind me upset. It seemed like the seats also would recline without even pressing the button in the armrest and would unrecline as well for that same reason, and it also seemed that some seats reclined more than others. The bottom cushions of the seat were so thin that even after one hour of an 11 hour flight, our tailbones were so sore. It seemed like an overall old airplane. It also didn’t have individual air vents and it was extremely hot the entire flight. Several passengers were commenting on how hot it was. The breakfast was some kind of flavorless triangle, puffy egg, laying in a watery bed of steamed peppers and onions and spinach. It was not appetizing at all. The flight crew was extremely nice so that was a nice thing this flight attendant. They let us try different types of Swiss sodas, which was really nice and the dinner was actually delicious but still overall given the other considerations. It was pretty much a miserable flight without basic seat comfort.

Food used to be better and comfort was not attainable after 5 hours everything starts hurting.

horrible.. they cause such a problem and my daughter 14 years old was stranded in san francisco

I can’t even the whole trip was a catastrophe

For that price on Business class, I expected to have the pod seats. These were configured as 2/3/2 and my seat mate talked half the flight with a friend across the isle, loudly. Very uncouth.

The ground crew members at check in counter were courteous. The boarding was seamless. Flight departed as scheduled. Service on board was great

Very comfortable in business class. Excellent service. Good food. Smooth trip.

The seats seems abit small and the reclining is too much, the seat in front of me came back too much and made it uncomfortable for me.

As a first time flyer with Turkish Airlines. My experience was very good due to the factor that there were to many passengers on the my first flight compared to my connecting flight. However, I know that nothing is perfect and all companies are trying to accommodate their passengers to the best way possible. I will always say, a FEW INCHES will go LONG WAY. That's something all airliners should consider, and not only the money aspect!!! A long time commitment is better than one time service! Thank you

Flight was delayed. While standing at the gate, a note appeared on the sign saying the gate had changed to a gate far away. No member of the Turkish airlines team got on the microphone to instruct passengers to go to the other gate, to ignore the chiron, etc. Finally, the message disappeared. Eventually, the flight began to board. Very slowly. More slowly than I experience with other airlines. Though Istanbul may just be slow . . . In all other ways, great flight, great entertainment (top notch movies), great service, excellent food, comfortable lie-flat seat, dimmed lights, etc.

Staff at the airport wasn't helpful or friendly. Probably the worst airport experience I have ever had, going and coming. The staff on the plane was better. Still not super friendly or personable. However, they were not rude like airport staff. They ran out of certain menu items. Maybe could have been prepared better? Overall just ok.

It was a pleasant experience. In flight entertainment could have been better

The desk crew at the LAX crew could do better. A girl named Mahesi was very abrasive and unfriendly. She needs a better customer service uproar.

It was peaceful excited We enjoyed it always Turkish peaceful excited

Flight was delayed by several hours and then cancelled due to weather. But Staff was very helpful getting me on a different flight. United should offer food coupons and tooth brush and paste for stranded passengers

I upgraded to the business class cabin. It was the poorest business class I have ever experienced. No access to any business lounge in Tampa airport. Seats are not comfortable. I had a window seat and had to step/crawl over the next seat. Food was mediocre and service below average for business class. Bathroom location was ridiculous. No place to wait. I cannot believe I paid this kind of money and will never fly Lufthansa Discover again. They really should reimburse me somehow.

Boarding was disorganized. The door to one to the toilets wouldn’t lock. The plane was shockingly cramped, and clearly used for domestic flights due to the menus for items to sell domestic travelers. United should be ashamed of its small seats, tiny unclean toilets, and money grubbing stance toward services, compared to Lufthansa, Emirates, and most international carriers United is awful.

Was never allowed on and not refunded the full amount of the ticket plus charged a $300 processing fee.

Terrible. Lost our luggage for 4 days. Did not advise passengers there was a strike in Barcelona Airport and had zero personnel on hand at airport to advise passengers on where to go to file claims. We had to fend for ourselves. No assistance at all other than an online claims submission process that we had to find out about on our own.

Lufthansa cancelled our flight from Los Angeles to Naples Italy on March 10 for scheduled flight on March 12 Very stressful experience trying to arrange alternatives. Will never fly again with Lufthansa

Everything could have been better. What needed to be wrong with United went wrong

The staff was bit rude when I asked for an extra drink after one beer, asked for one wine glass.

Very good, i got two seats for myself, and was comfortable with the blanket i got

I hated the FRA Airport. Confusing signage, including the path to Immigration and Security It seems that the airport grew haphazardly over the years. I have been through multiple WW Hubs with much better experiences.

Flight was canceled. Rebooked on Lufthansa Also Canceled. Had to pay 3000 more per person and fly Alaska to EWR and fly emirates to Athens.

ITA changed our 9 hr direct flight without giving any reason to 4 stop overs 24 hrs flight without delays.

Our flight was cancelled the day before our trip and we we put on a Turkish Airline flight that got us in half a day later.

The flight I initially booked from Los Angeles to Florence. I made sure had a layover of about 90 minutes in Rome, so there’d be enough time to connect. A couple weeks before the flight for some reason I was updated that that flight had changed and I was only gonna have 60 minutes to connect. From LAX we were delayed by 45 minutes meaning making the connection was unlikely. The crew informed me that my connecting flight would not wait and they would rebook me on one four or five hours later. I wasn’t happy, but I accepted it. It is what it is. Except when we got closer, two separate flight attendant approached me eagerly and said they had great news that my connecting flight would in fact wait for me, but I needed to hurry through the airport so they didn’t have to wait too long. I was first off the flight. I ran about 4000 steps. And got through passport control all in under 15 minutes. When I arrived to my gate, I was greeted by a flight attendant there who was completely indifferent, said they didn’t hold the plane and they just closed the doors. Had they even held it for two minutes I would’ve made it. She simply told me that the flight attendant on my flight lied about the plane being held, and that they do it all the time. These were all employees of the same company ITA. I was absolutely livid at her indifference and having been lied to and then having to wait five hours and waste a day in Europe at an airport.

The flight was canceled and we have not received the refund

Flight attendant really had bad behavior.. yelled at people when she is trying to defend, to have favor w her people..!

They lost my checked in bag and have not helped me.

I did not leave to Italy yet. We had technical problems on flight from SF to Maimi and had to land in Denver and wait for another plane to take us to Miami, so I missed my plane to Italy. I am still waiting for the Agency to fix my flight till today the haven’t done anything and I am paying for my Hotel stay. Everyday they are promising to fix my flight, they are not doing so and they are not even looking for another solution

Need better food options. Need warm food both times Stevie was provided. Bathrooms are too small. For an international flights, seats are small and leg room isn’t enough. And for an international flight, serving spirits should be included, not just Italian beer and cheap wine. All the tv/film entertainment is quite old and not updated, but the size of the screen was good.

My seat was broken and ducted taped and my monitor did not work the entire time over 8 hrs sitting. And I had no books or anything with me

Boarding and flight itself was smooth and temperature during the flight was perfect. It was just overall vibe for long distance flight, felt cheap ( comparing to KLM or TUI that I used recently). Entertainment out of date movies with poor picture quality, no games, flight map wasn't working

Basic, 737 Boeing, business class is just an economy class seat with blocked middle seat (European standard).

Entertainment is nonexistent. Food might have been good, however due to language barriers I didn’t get to have any food. Flat bed seats and layout was excellent. Crew efficient and straightforward, but lacking any western style approach. Not that I’d expect anything else, but one could have hoped.

Unorganized, late and they lost my bag for several days.

Flight took very long to even get checked in for, everything was late and written out by hand. My luggage was lost for several days and it was the most unorganized flight experience of my life.

Delaying more than 5 hours from Belgrade to Tirana Information very rude to questions

It's the shortest trip one could get from BEG anywhere, so it was fine.

I paid for luggage when I bought the ticket but I could not board until I paid for luggage again. The fault lays at the feet of eDreams, the company that booked our flight. Sorry, Air Serbia, but it did affect the boarding process.

They had lost my ticket and despite showing them the confirmation email with the itinerary and receipt of payment for the flight they could not put me on that flight and rescheduled departure postponing it by a whole week

Kraljevo is very convenient airport. It's brand new, small.and efficient. Great job!
