Pros: "Excellent food and crew"
Pros: "Arrived on time"
Pros: ";Flight attendants very attentive;"
Cons: "Leg space far too tight; could barely move; Unable to see TV screen due to angle, even at max tilt; Food was inedible; perhaps acceptable as dog food; Toilet seat would not stay up for male to pee. Worst international aircraft I've ever experienced. Recommend upgrading before selling any more seats."

Pros: "Very friendly and efficient Good food"
Cons: "Zürich airport early closing at night so difficult to check in and drop off luggage"
Pros: "movies choices were good, the crew was awesome, boarding was meh, but for NBO not bad"
Cons: "paid extra for the seats with more leg room and the amount of leg room I had was concerning in terms of what a regular seat may have looked like. I'm not even that tall, but when the woman in front of me reclined, I was pinned in my seat. Luckily I'm double jointed."
Pros: "Good film selection -which unfortunately I couldn’t watch. To be fair I got a 50 CHF discount for my next flight with Swiss."
Cons: "Entertainment system wasn’t working in my row. Food was not great, not the standard I’m used to from Swiss. Took them forever to turn on air handling after boarding, plenty of time for All the people with colds and coughing fits to infect everybody else."
Pros: "Smooth flight"
Cons: "I ordered a kosher meal and did not get it. The seats are very uncofmfortable. When the one in front puts their seat back it goes almost in to the face of the one behind."
Pros: "Flew Business class to Zurich. Great service, completely flat fold down seat so sleeping is EASY Great price."
Cons: "Transfer in Zurich airport security. We were transit but it diodn't matter because we took a 3 min train to another terminal and had to go through security again. No bank in Terminal B to change money ! In Switzerland !!!!!"
Pros: "Flight itself was good for a shorter international flight. Dim cabin lights for early morning, crew providing plenty of drinks and snacks."
Cons: "For international travel, I’m always told to get there 3 hours before. For this trip we checked in but didn’t have access to a printer so needed a boarding pass. We wanted to carry on luggage so just needed to print the pass. Swiss was the only airline that wasn’t available on the check-in kiosks. The front desk staff didn’t arrive until closer to 1.5 hours before check in so nearly theall passengers were in a huge line to get passes and check bags."

Cons: "Snack choices too limited, but it was great that they even had them."

Cons: "HAving to walk across the Zurich airport to buy a business class upgrade was bad. I just wanted to buy the upgrade at the desk. No need to go from terminal 3 to terminal 1. total waste of 20-30 minutes. Ironic that this happens to people willing to spend $'s of dollars for convenience and comfort. should be able to purchase upgrade ASAP with a smile at check-in."
Cons: "Our luggage was left behind in Zurich after an unnecessary gate check. There were plenty of room in the overhead bins, and we purposefully bought the luggage because they were sized for bin storage."

Cons: "Nothing"
Pros: "Flight attendants where very nice and attentive. Good choice of movies and shows for adults and kids. I usually don't eat airplane food but it looked fresh and my kids enjoyed the breakfast very much with fresh baked bread and croissant.

Cons: "Boarding was a little chaotic"
Pros: "The plane was clean, on time, and the staff were professional and friendly."
Cons: "I opted for the pasta dinner and it was bland and mushy. Salad was boring iceberg lettuce."

Cons: "Both flights from Swiss (from Münich to Zürich and the flight in the opposite direction) were delayed by 30 min and 1h, respectively."

Pros: "fast, all good"
Cons: "-"
Pros: "The whole trip was handled extremely well. First time we've done 12 hrs straight in the air. They made the experience seem like it was much less. Will fly that airline again."
Cons: "Sound for on-screen entertainment not working. It was static-y all the time and completely cut out the rest of the time. I made various attempts to solve the problem, switching headphones, switching to my own headphones (which can't really be done because they have a two-prong jack and personal headphones are always one). I tried watching different movies, programs, music...it wasn't the material I was watching that was the problem. I asked the flight attendant to reset my console. That didn't work either. I just ended up reading my book the entire 9 hour trip."
Cons: "The seat was horrible and had no cushioning. Left . Worn out and non manintained seating systems . Had body pain"
Pros: "Comfy, loved the individual Tvs and food was great!"
Pros: "I have been flying to Greece and back many years now.

I really wanted to travel with Swiss, because they have a Ski bag included on the luggage. I ended up paying extra bag in United."

Awesome thanks to the crew

We had 1h delay. We waited in the place for the whole time.

Pros: "Both friendly and professional"

Pros: "Nothing."
Cons: "This was the worst airline I have flown with. I booked my tickets last minute, it was for me and my 4 month old son. I had 3 suitcases a stroller and 2 carryons. I had paid for the suitcases, but because I was traveling alone I went there with my husband and he politely asked if they could please take the carryons on the plane because she can’t carry everything by herself. The manager came out and said that we have to pay. I said I already paid extra for my suitcases please help us because my wife is carrying our son, the diaper bag and 2 carryons. He was rude stating that we have to pay each carryon. We didn’t have the extra money and my wife took everything with her. If that’s how Turkish Airline treats their customers, they shouldn’t be operating. It was the last time I use this airline. No dignity or humanity, it’s all only about the money. And when I took the stroller with my son. They made me package the stroller by myself looking that I had my son on me crying and when I asked for help they said that they can’t help me... unbelievable... they see me with 2 carryons a stroller and a baby and they can’t help me."
Cons: "Food had only beef options"
Pros: "The bathroom was clean in the beginning of the flight. Speak some English ."
Cons: "Their crew wars lazy . In 12 h flight I got coffee only once . The food was ok, bread was old. Airplane was dirty. Called for flight attendant but had to go to look for them by myself . By the end of the flight there was hardly any jews laughed and no Lamons. The plane was not ready to be full Of people."
Pros: "The crew is phenomenal"
Cons: "They had a deported person sitting next to me. The person was in jail and he showed me the court order That made me very uncomfortable."
Cons: "Nothing"
Pros: "The Airbus is such an extremely "customer oriented' airplane."
Pros: "The food was quite good"
Cons: "The new type of aircraft - less room between seats, entertainment system was poor, online check in didn't work, when I got to the airport I was sent away for an hour - was unable to get my prefered seat (window) by the time I had returned."
Pros: "i like because can interline from qatar airways and baggage through as well. so i do not need to check in again."
Pros: "Awesome"
Pros: "The check in at Budapest was very helpful."
Pros: "Boarding process started early and was efficient. Short flight so not much to say."
Cons: "We seemed to arrive late even though the boarding started early. Last call was displayed on the monitors 40 min before the flight took off which seemed excessive to me. And in spite of this we still didn’t arrive on time."

Pros: "i like the reception"
Cons: "i like how the crew welcome me.i all so like the food"
Pros: "Very crowded on the plane with little leg room and very difficult to pass down the isle to get to the bathrooms. Food and entertainment were very good."
Cons: "The layover was too long."
Pros: "Short but comfortable and pleasant flight."
Pros: "Electronics confiscated from passengers (all passengers, no profiling or consideration for who is dangerous and who is not, which is NOT WHAT I LIKED, I hated it, this political correctness, so everyone "suffers the same", while bad guys still have all the freedom to do terrible things. It is not a security, it is a stupid put on!) but at least our electronics were carefully packed and delivered to Boston. It took whole hour afterwards to retrieve them!!! Terribly inefficient."
Cons: "Stupid, completely idiotic security, caused, of course, by our completely idiotic president Trump rulings, but... Turkish air workers took this stupidity up to an unseen levels. I fight stage 4 cancer, it requires timely medicine. I was not allowed to take on board several critical supplements because they were either in powder, granulated or liquid form (all in their original medical packaging), my custom made crocheting hook was labeled as a dangerous weapon and I was not allowed to take it on board either, so I had no means to alleviate my air flight anxiety. they were going to confiscate and throw it away. Cold "sorry for your loss" was their only reply. They tried to scare me by calling police. Extremely impolite personnel. It took almost two hours, when TA security threaten that I won't fly, to make them pack this little darn crocheting hook together with my iPad. Funny that food on board comes with real metal silverware, forks and knifes included, which are far more convenient and dangerous if I was to use it as a weapon in comparison to a hook (3 inch wooden handle and 1 nah of a metal shaft ending with a small blunt hook, thin - size 2). TA said they provide us with free wifi to compensate for confiscated electronics. I was not able to connect to that wifi all flight long. Movie selection is below mediocre, little choice, practically no quality. Food is bad - not appropriate for my condition at all, but of course I can't bring on board cancer-appropriate food - security labels it as a threat to passengers. No leg room at all for a medium-built lady like myself, can't imagine what thicker or taller people do to survive 9+ hours flight, seats do not recline, pull out tables are of terrible quality- very unstable, so food and drinks fall off even without turbulence, just because of no leg room our knees are always interfere with these flimsy tables. With a comfort and restrictions like I had tickets must cost not a penny over a bus or metro ride, not hundreds of $$. It took about two hours to get my suitcase too - they said our luggage had to go through a second inspection before it gets onto baggage carousel. All in all, I will avoid TA for long flights by all means. Never again. They were an huge downshift to my perfect vacation. I had to go to an emergency treatment today because of the way TA treated me yesterday. Unfortunately, I can't measure how much yesterday's abuse advanced my disease, I am disturbed and frustrated enough to go to court to bring a suit against... yet again, those imbeciles from security do have a good alibi - their actions were triggered by US government regulations."
Pros: "We boarded on time, very well run, the food was great, great movie choice"
Cons: "The seats could use upgrading. I've flown aturkish quite a bit. Some planes have comfy seats, some are very still"
Pros: "The entire inflight experience was great from start to finish."
Cons: "I approached the Transfer Desk when there was no line and asked the person working if it was possible to switch to an exit row seat because of my height. The man helping me lied to my face and told me that he could not make the change because the flight was full. when I got on the plane, there were over two dozen empty seats. It was very clear that he just did not want to invest the few seconds it would take to address my concern, or give me a credible reason why he could not make the change."
Pros: "I liked the aircraft. They were fairly new and well maintained. New inflight entertainment and movies. Fairly spacious for a medium sized person."

Pros: "The best flight ever!"
Pros: "Love this airline!!"
Pros: "Everything was the best! The food, the movies etc on board to choose from, the staff, everything was great. Turkish airlines is the best airline I've ever been on—US companies need to take note! Even on a 2:10 flight we got a full meal and many drinks."
Cons: "Nothing! Everything was perfect!"
Pros: "Everything from above and the fact that my bags got home untouched and on time. It would have been a disaster to have to drive back to Bucharest to pick them up at the later time like it happened with other airlines."

Cons: "Excellent"
Pros: "Nothing"
Cons: "Poor Business class Entertainment system didn't work Seats didn't recline Boarding was terrible Staff at Istanbul airport very bad Organisation terrible support very bad"
Pros: "The entertainment choices were quite good. Flights arrived more or less on time."
Cons: "Our departure flight (BOS-IST) was changed 6 weeks after our booking, so our 2.5-hour layover became 10 hours. This happened before in my past experience with Turkish Airlines. There were many babies and small kids, so the noise level was high. Not ideal if you want to get some sleep on the flight."
Pros: "In flight entertainment was awesome, Wide selection of movies to keep occupied."
Cons: "Food was okay but can be improved, needs to have more variety and more local touch in the cuisine offered."
Pros: "Prompt service throughout."

Cons: "food"
Pros: "It got me from point A to point B safely; it was a short flight. The overall price of my flights couldn't be beat."

Pros: "Crew was very pleasant. Boarding and deplaning was smooth and easy!"
Cons: "Slight delay"
Pros: "Good"
Pros: "Availability of WiFi, a charging port and media options puts Delta a step (or two) ahead of their competitors. The professionalism of the crew, as well as the complimentary food/beverage options are also excellent."
Cons: "Not the airlines fault, but my 6’4” frame doesn’t fit very well in a middle main cabin seat."
Pros: "We arrived eventually."
Cons: "Flight delayed three hours. Payed extra for an earlier flight. Very disappointing."
Cons: "Delayed 4 hours"
Pros: "Flight left on time and landed on time"
Pros: "Crew."
Cons: "Getting to Venice on time. Our late arrival cost me a 90 euro shutle."
Cons: "Choice of healthier snack"

Pros: "Good airframe."
Cons: "3+ hours delayed; didn't arrive until 3AM."
Cons: "Seats are so small. Flight was delayed."
Cons: "Denver airport is far too large for there to be such a small security check therefore it took forever and I missed the flight. Delta tried to charge me $1000 for another ticket to Albany and I decided to fly with another airline for half the price instead"
Cons: "The seats were in bad condition, I was surprised as Delta usually has well cared for interior and exterior airplanes."
Pros: "Professional appearance of flight staff accommodating and sincete"
Pros: "The flight attendants were all helpful and pleasant. The seats were comfortable. We were provided with plenty of liquids."

Pros: "Short flight"
Cons: "In SLC they boarded by row numbers and not zones. Weird..."

Pros: "Good flight crew"

Pros: "Everyone was fairly friendly"
Cons: "Cramped foot room"
Cons: "Bags never arrived at the listed baggage claim. After 45 min, I saw bags on a different claim station and I notified everyone standing around. BUT, I filed a claim with Delta and was immediately given 2500 miles, as guaranteed!"
Pros: "Great people and crew early arrival nice passengers"
Pros: "Nothing!"
Cons: "Everything"
Pros: "Delta is great"
Cons: "Poor Delta DEN counter agent experience. Name on ticket didnt match Delta profile name nor TSA [rofile name. Delta counter agent would do nothing, except blame TSA. Would not check ticket name vs profile name. Happened two consecutive flights. Flight tomorrow morning has no TSA Pre clearance on boarding pass. This will be three consecutive flights. Also seated me next to a person who needed 2 seats to himself. Please never seat me next to a passenger who cannot fit in their own seat. I am switching to SWA."
Pros: "On two of the legs of the trip they notice I was a tall person with long legs and upgraded me to seats with more leg room!! I didn't even ask. Thank you."
Cons: "On the way back there were open seats with extra leg room and I asked the gate attendant if it was possible to switch my seat to one with more room and they said they only could if I paid extra."
Pros: "Crew was nice."
Cons: "The Entertainment sucked. Again I was sitting in comfort class which in theory should buy you more comfort and better entertainment. There was a ton of movies from the 90s and the same movie selection from about 6 months ago when I traveled with them. Also, what is going on, with having to use your own cell phone to watch movies on the plane? Whatever happened to the screens in the backseat of the front seat? I ended up with neck pain from trying to watch a movie on my phone. Delta has become very cheap. It is going into some serious decline."
Pros: "Nothing"
Cons: "Let me just say that I’m a loyal Delta costumer until now. The flight attendants (the two women) were an absolute nightmare. They were so rude and condescending. I was carrying with me my service dog and a bag containing an expensive medication (it couldn’t go on the top bin). Despite being in the comfort class and having the seat next to me empty, we were tight for space. The flight attendants were unreasonable and forced me to put my medication on the top bin despite the fact I had told them it was extremely delicate, that it that to go upright, and that I needed to keep it with me. They did not listen and pressured me into giving them the medication. The medication could have easily gotten broken. Thankfully it didn’t but this is no way to treat a human being."
Pros: "Entertainment system is awesome and similar to what I usually see only on international flights."
Pros: "Ran smoothly, typical flight, everything was as to be expected. Everyone was polite and courteous."
Cons: "Tight seats, boarding process was a bit lengthy, and we hit some turbulence (obviously beyond anyone's control). The pilot and crew handled it well."
Pros: "What a city.. Unique for hell sure..."
Cons: "Nothing"
Pros: "Crew was the best!"
Cons: "I really dislike the snack boxes. Snacks need to be more like a small sandwich or grapes, cheese and nuts. Not all that packaged stuff."

Pros: "Excellent crew and comfortable flight"
Pros: "Great,I loved it!"
Pros: "Food, crew, boarding"
Cons: "I had a screen in front of me that did not work. It was annoying. Fix it."
Cons: "I fly Delta quite often, and am usually pleased with their service, but the morning of June 23 was terrible. I got to the airport in Denver at 5:30 am for a 7:30 am flight to Atlanta, and the line to check a bag was about 40 people long. I waited 55minutes to check my bag, as they kept moving the ski priority people, and people in danger of missing their flight, to the head of the line. There were obviously not enough Delta workers on staff to process all the flights at that time."
Pros: "The moviea"

Pros: "The bathroom downstairs"
Cons: "Late arrival inMunich, rush to connection and my luggage didn’t make it"
Pros: "Everything is good"
Cons: "Food use to be better"
Pros: "Visa for India was not checked in Denver. Landed in Frankfurt and discovered that the visa was expired. Stuck in Frankfurt for 3 nights until new visa was issued. No babes the entire time I was in Germany. Arrived in Mumbai after paying the $350 US change fee and no bags. Bags finally arrived on Monday at 9AM Without clothes, toiletries and medications for 6 nights. Now I am delayed and will probably have to pay rebuke and fare change to extend my stay here."
Pros: "Lufthansa is extremely efficient, and the staff is very helpful all while being cheerful and kind. The planes are new and clean, everything was a notch above typical economy carriers. Well done!"
Pros: "1 hor 30 minutes instead of 2 hours 15"
Cons: "Worst food ever, and zero entertainment"
Pros: "W we’re a few minutes late and they waited for us. We truly appreciate their cooperation. 5 strat services."
Pros: "I liked that if I asked for something the crew would get to me rapidly. Extra leg room."
Cons: "Boarding process: just a lot of confusion. Inflight crew service poor: the was no time to have any brain reaction when they would pass by with coffee or anything...and when I asked for coffee the answer for a gentlemen of the crew was: coffee already passed by. Really!!?? Make sure that +$1200 are spent well. Rude or inattentive crew members shouldn’t be on flights that are that long...I had to nsist to have a miserable cup of coffee. Movie selection was poor. USB port didn’t work. Shame on you!"
Pros: "At least Lufthansa has a little bit more leg room."
Pros: "Efficient boarding, friendly crew."
Pros: "The best in-flight service I have ever had on the Lufthansa flight from Denver to Munic!"
Cons: "Couldn't reserve a seat, even 24 hours in advance because web checkin was turned off. Ended up in the middle of the middle on both directions."
Cons: "It seemed llike the boarding was rushed and a bit hectic."
Cons: "We were charged a rebooking fee by Lufthansa when customs searched luggage causing us to miss connecting flight"
Pros: "Great crew service"
Cons: "Didn't happen yet."
Pros: "Timely."
Cons: "Seats are small, no entertainment, food was below average."
Pros: "the crew are exellent"
Cons: "Entertainment options were not too good. The flight should have more American sitcoms and more Hindi options."
Pros: "The entire experience was great. Easy check-in, boarding, on time, friendly service, good food, good movies, and overall a really nice atmosphere for such a long flight. Would recommend this Flight to anyone."
Cons: "Nothing"
Pros: "The overall feeling of this flight was 'relaxed'...after getting over the fact, that this was a huge (two story) airplane. Short flight from Denver to Frankfurt...only 8 hours:)"
Cons: "I would have loved to be offered eye shades and ear plus, since most passengers watched movies and i wanted to sleep:)."
Pros: "Flight was on time comfortable good crew clean and upbeat"
Cons: "Boarding"
Pros: "flight was on time and the crew was wonderful"
Cons: "Plane was"
Pros: "Great service, crew attentiveness and economy comfort. Movie and music selection was good."
Cons: "Slightly larger food portion"
Pros: "Good flight good seats smooth ride."
Cons: "Boarding was not organized."
Pros: "Good job keeping up on food and beverages. Entertainment was great. It was a long flight but was manageable with great service"
Pros: "United is a good partner to Lufthansa. I like United. It was a quick flight, but a good one."
Pros: "Nice crew"
Cons: "Lack of leg room!!! After my bicycle box was inspected they failed to secure my bike the way I had it in the box. Bike was flipping around in box. Bent rear brake calipers. Bent brake hoods. Rear skewers were uncoupled. No way to treat a $10,000 bike! Very upset!"
Pros: "Pleasant crew."
Cons: "Annoying kids in seats behind us :( Not enough leg room for someone over 6 feet tall."
Pros: "The flight was on-time!"
Cons: "The food was mediocre."
Cons: "Rude (American) passengers not keeping the "curtain down", when it was time to rest, and being very chatty. Also baby crying, but this is inevitable, it happened to all of us, when we had small babies."

There was nothing to complain about, but we were in business class so it's hard to know what the experience would have been like in economy, which is how we usually travel.

There is no entertaining offered on the shorter flights. I wish that would change.

Comfortable, free snacks and coffee/water, ghod entrrtainment

Cons: "Food/drinks Tv"
Pros: "Nice staff"
Cons: "Seats was locked and could not be reclined"
Cons: "3/3 flights I’ve taken have been delayed. I never made my connection, adding 10 hours to trip, more than doubling travel time. LOT is consistently late. Be aware of short connections. Or really any connections."

Pros: "They asisted me with blanket to cover with"
Pros: "New airplane , clean , Spacious Seats at the premium class Fast crew service ."
Cons: "You cant use the entertainment during the take of and landing ..."
Cons: "Because LOT flight from Lviv was late we did not make the connecting flight to New York and had to spend the night in Warsaw."
Pros: "Brand new plane, very smart albeit plasticy and clunky. Professional staff. Very helpful when I had a specific personal request at the booking office. Flight crew were not constantly trying to force us to buy things or making announcements every 5mins like some budget airlines I could name. Flight was 30mins early so no problems there."
Cons: "Warsaw Airport is terrible. Not enough seats in the departure longes. Not enough choice for shops. Not enough toilets for the volume of passengers."
Pros: "Courteous, knowledgeable and professional crew. Fast boarding. Direct flight."
Cons: "No wifi. Little room if person sitting in front leans back."
Cons: "Crew was grumpy. It was a problem to get a full glass of water. It was always a half of glass and no ice. Even in warm pop-no ice Food was not up to standards. Seats no leg room If crew was nice and smiled. Would have helped"
Pros: "The flight starts 2,5 hours later."
Pros: "Delayed. Moved gate without notice. Babies crying all the way"
Cons: "Too noisy."
Cons: "Incomfortable chairs"
Cons: "2 hours late !!!"
Pros: "The crew was hospitable and warm. All the in-flight service was attentive and high-quality. We had a wonderful experience with LOT and would reccent them."
Cons: "The only potential difficulty was the short layovers. We made our connection boarding with only 20 minutes to spare."
Cons: "Baggage policy was confusing end I ended up with baggage fees about the same cost as the flight"
Pros: "Not 1 thing !!! Bad.bad.bad"
Cons: "The legs room, no free meal, on the flight from warsaw to tel aviv. 1 hour late on departure from warsaw to tel aviv"
Cons: "We could not board at the gate, but had to go down stairs to the tarmac and board a super crowded bus. The bus then took us out farther onto the tarmac to the plane."
Pros: "ok"
Pros: "Great crew. Waited for passengers from late transfer."
Cons: "Too small."
Pros: "Appreciate the heads up on flight changes"
Cons: "NYC to Warsaw, the flight was 4 hours late no voucher for food. some got it some not. i lost the flight from Warsaw to Bucharest they put me on flight from Warsaw to Vienna that flight was late as well i got to Vienna and i ran to get the flight to Bucharest. i was very tired"
Cons: "Bathrooms"
Pros: "Ok"
Cons: "It's nice when an airline overbooks a flight."
Pros: "Everything was great"
Cons: "Nothing to complain Everithing was great thank you"
Pros: "LAX - Warshaw rotation looks underutilized, so should be easier to find cheap biz fare or get an upgrade. The 787 is a spacious plane up front, but LOT uses the traditional 2-2-2 layout with no direct aisle access from window. Also means you're still sleeping close and next to a total stranger. I don't know, I've so gotten used to Delta's biz layout with their direct aisle access and no touch points to a fellow traveller, I don't think I can look at anything more traditional as not a compromise and downgrade."
Pros: "The flight was smoothe"
Cons: "Boarding was a mess and is always a mess"
Pros: "I liked that the food was better by comparison with food served on other airlines (part of Star Alliance)."
Cons: "I think it would be nice that staff /crew addresses the passenger in both Polish and English. Most of the time they used only Polish, did not try to ask in English at all.Of course, if I asked for something in English, they can understand and respond. Also, did you always charge for wine and beer? Otherwise, I appreciated it was not as expensive as on the airport or on other airlines."
Pros: "Not bad in general, reasonably price/quality service"
Cons: "I do not like when departure delayed"
Pros: "Boarding was relatively quick"
Cons: "After the first hour when food/drinks were handed out, the cabin crew (Economy) seemed to disappear entirely to the back of the plane and spend the rest of the flight chatting with each other until the final meal just before landing. I don't expect champagne service in Economy but the flight attendants could have been more proactive in walking down the aisles occasionally rather than just when handing out meals. If you needed a drink the best option was to head to the back of the plane and pour it yourself. In fact, most of the passengers did precisely this!"
Pros: "The entertainment on the plane was great. Large selection of movies, music, and TV shows to keep yourself entertained. The dinner was adequate. It was also nice having the overhead screens continually update our flight progress."
Cons: "The seats are incredibly cramped, by the end I was feeling seriously claustrophobic. It didn't help that we left late. The boarding process was a mess, nobody seemed to know what to do, and the announcements were all mumbled to the point where I was just guessing what to do. The second meal served was inedible as the bread was completely stale. Also, one of the toilets was broken and kept flushing, even when sitting on it. Like the boarding process, disembarking was sloppy and confusing. It took a very long time to open the door, and they only told people at the last minute that they needed to get their passports out."
Pros: "Very helpful staff during boarding very good dinner"
Cons: "breakfast meal - very dry sandwich with only one slice of cheese no internet access during flight inability to use headphones during take off and landing"
Pros: "Very comfortable aircraft and real value for money."
Cons: "They provided only one option for food for the second meal. It was not bad but sometimes people prefer not to eat meat-only option."
Pros: "Just a wonderful experience.The most comfortable plan,The most concerned and efficient crew,wonderful service.I will recommend Lot to everybody."
Pros: "easy check in"
Cons: "took off late and boarding was kinda messy"
Pros: "The flight was operated by LOT Airlines. The benefit of booking through Croatia Airlines is that I got to check a bag for free. If I had booked through LOT, it would have costed me money."
