I have flown with LOT several times and regret it every time; however, they are the only airline that offers the direct flights I need. Boarding was awful. I was alone with 3 children, including an infant, and we were forced to stand in buses packed like sardines. Then, for such a large flight, there was not even a gangway. I was expected to carry a baby, a carseat, and luggage by myself up the dangerous steps into the plane while the crew RUSHED me. The crew was very curt, cold, and inattentive. No one offered any assistance or sympathy to me alone with kids. There was no ventilation or AC in the plane.

My ONLY complaint with LOT was the lack of WiFi and the food in business class… still, I use them because they have great connections to Chicago and they fly the 787 - which I think is a great wide body jet. Well… now LOT has WiFi (good satellite speeds) and AMAZING food. LOT now is giving Turkish Airlines a big big run for the money. And they consistently have less expensive business class. I am a very happy customer!

Issue with boarding, group of passengers on a religious trip coming back to NYC kept trying to change seats, even standing when the plane was pushing back. Crew/Pilot kept very good composure, some passengers got aggravated and started venting out loud but this group created a serious security risk. Crew/Pilot should've been more stringent and called in security or remove them from the flight.

The seat was paid for but given for some different person .

Krakow airport is very disorganized. nice seats. friendly crew. long legs had screens. short leg did not

Flight was delayed for a hour from Warsaw, not sure why. When we landed in Chicago, plane was still on the runway for about half a hour. Took a while to get off.

No WiFi and ok comfort in business class. Home safe I guess that’s all that really matters.

I would like to be able to choose the seat before the flight without paying extra money. Family members should not to be separated from each other.

Flight was delayed by a hour could have been better addressed. Flight was fine with great service by the flight attendants

All good. Didn’t get the seats I booked online. Luckily, copassanger cooperated! Mistake- I failed to verify connecting flight seats details at Mumbai. Staff at Mumbai airport to be blamed equally!

Excellent excellent flight! I’m sure it helped that the turbulence and the weather cooperated, but the staff was wonderful. The legroom was perfect and my husband is 6‘1“ and he felt perfectly fine. Best flight I’ve taken in a long time.

I have no Comment. Super clean, Fantastic Crew, Food was delicious. Also wanted to add the Zurich Airport. Super nice people everything is in order super clean.

I like it very much it was a good experience with an excellent service

The boarding of this flight was total chaos. For some reason, all passengers had to stand in a lengthy line at the gate to have our passports checked for the FOURTH time. No reason was offered for the necessity of the fourth re-check, and when we got to the end of the line, the check was perfunctory. There was little to no crowd control at the gate and in some cases, tempers were flaring. On the other hand, once we got on board, everything about this flight from start to finish, especially the quality of the food and the service, was probably the best I have ever experienced..

The seat and leg room is small on the 2 seated row. Otherwise, very good crew and service.

The meal was wonderful and strawberry ice cream was a plus.

I haven't flown Swiss in a long time. I was disappointed that after paying $14,907 for 3 business class seats, we still had to pay another $200 for a single business class seat. All the window seats used to be single seats. Now it's every other one and if you want a single seat it's extra. Also, The double seats do not have pods or any privacy. We landed in Chicago after a long 10 hour flight and our connecting flight was on United. Because we do not have status on Swiss, we were not allowed to use the United lounge, even with business class seats. My father is on crutches and we had a 4 hour layover. No lounge was also disappointing. All of my status is on British Airways so I will go back to flying BA. We flew Swiss because my father did not want to go through Heathrow. On a positive, the crew were super nice and accommodating for my father who had recently had hip replacement surgery. Food was okay. I"m not a good person to critique the food, I never like airplane food.

-Swiss airlines online check in app crashed multiple times -Zurich airport does not have very many bathrooms accessible to people with disabilities - closest disability accessible bathroom to departure gate was 1/4 mile away.

Plane was late so luggage never made it to connecting flight. I’ve been home 2 days and still do not have my luggage.

Wheelchair was the excellent service. I didn’t have any food or used entertainment. Overall for my trip experience was excellent. Thank you very much and keep up good work. Best regards

Bussing in a major flight is idiotic. Cabin was too warm. Food was bland and felt old

Turkish airlines feedback team response is awfully slow, and because of that, I Emmy able to bring my little dog with me, after all those preparations.

4 flights booked with specific seats together and a bassinet. All 4 flights were seated separately without a bassinet

Horrible service at the baggage claim. Stuck on plane for an hour due to taxing and no gate.

I really would like it if they provided at least some limited free wi-fi.

I missed the flight during my lay over in Istanbul, due to health condition. Customer service was awful. It was a nightmare. I had to purchase a new flight to my destination and was told that my return flight is compromised due to one segment of the trip being missed. NOBODY responded to my numerous calls and emails. I will never use Turkish airline in the future.

Excellent food and service on my international flight. Most notable is the food provided by Turkish even for coach passengers is very good.

Food is very turkish. No regard for other natinalities taste and preference. The entertainment can be improved- it was the same menu on 10/8/25 and 10/25/25. The boarding is the worst in the airline industry- I suggest you ask your staff to and watch how other airlines do it.

Everything was so smooth. It could be just a better temperature in the plane; it was a little cold.

We couldn’t fly to Chicago on our booked flight. The flight was overbooked.

I'm a nervous, autistic adult. The staff were very friendly and answered my questions and came by at regular intervals to check everyone's comfort. They even resolved a fight between two couples in front of me!

roomiest flight in economy I've taken in years. Excellent experience!

I was booked to travel from Dallas to Nairobi via Chicago and Brussels and had been issued boarding passes for all three segments of my journey. At the boarding gate in Dallas, I was required to check my carry-on luggage due to limited cabin space. Despite my attempts to explain that I was traveling internationally and would not have access to the bag during transit, my concerns were not considered. I also informed the staff that I did not have a padlock to secure the luggage, but this was disregarded. Consequently, I had to hastily transfer essential items from my carry-on into my handbag. To my surprise, upon arriving at Chicago Airport, I observed numerous international travelers boarding with cabin bags that were significantly larger than mine. This experience left me extremely disappointed and led me to decide against using United Airlines for future international travel, a sentiment I have also shared with friends and family. Unfortunately, the onboard experience on the Chicago to Brussels flight further reinforced my dissatisfaction. The cabin crew appeared disengaged, indifferent, and lacking in attentiveness, resulting in a service experience that fell well below my expectations.

You deleted my connection ticket home and I am stuck in Seattle!!!!!!!!!!!

It’s not bad, simply it’s not as it used to be years ago.

The flight was at 6:10 am to early. No coffee or anything else offered. To 👎

Boarding was confusing with all those lanes and groups. Everything else was good

I was charged $370 dollars for one luggage in Belgrade and after trying to contact a supervisor he didn’t have time for me and said there is nothing I can do with the charge still pending.I paid $75 dollars on the way there. I only realized it after I received a text from capital one. I’m very disappointed because my family a I travel with Lufthansa often sometimes twice a year.Poor customer service not sure I will be traveling with Lufthansa anymore or recommend it!!!

Smooth flight, pleasant crew, food was ok, our seat didn’t have a throw up bag when we needed one.

The flight crew did a great job handling a volatile passenger.

No option for gluten free meal - even to pre-order. Crew basically said: 'meh, deal with it'

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).

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

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.

Long delay (6 hour late departure, not informative enough to provide up to date info on flight, poor food quality

Plane was old. Seats were hard and very close together. No in flight entertainment.

This flight was better, plane was newer and didn’t have broken parts. Flight crew was very attentive and friendly.

Our flight was delayed from 1st July to 2nd July. But I wasnt informed! Checked my emails,every detail but I was definitely not informed! I and my family went to the airport on 1st July and learned that rhe flight is delayed to 2nd July at the airport! I am going to complain about this. I had to stay ın Kraljevo one more night. Luckily we could find a room. What ıf We couldn't?

To be honest, it was a fair flight, nothing more, nothing less. Since the route is short, I can accept poor in-flight service. The Belgrade airport is currently undergoing extensive reconstruction, which may result in some minor disruptions, but progress is expected to be made within the foreseeable future.
