Boarding was impossible to navigate. Had mobility issues and a business class ticket, but still boarded almost at the end of the queue because there was absolutely no organization or assistance.

Boarding was impossible to navigate. Had mobility issues and a business class ticket, but still boarded almost at the end of the queue because there was absolutely no organization or assistance.

Aircraft was new. Food so so, especially vegetarian was very disappointing.

Very courteous staff. Abnoxious passenger in front of me who reclined her seat all the way without warning and without considering the person behind her. My flight ORD-WAW was so much more pleasant because of the courtesy of the passenger in front of me.

LOT told me on my first flight that I had missed boarding my second flight and told us to go to a service desk to reschedule. We then were told our flight was still boarding and that we had to run through the Warsaw airport to catch it which is just a long long runway airport. The workers at the airport were not helpful at all and you have to go through two passport checkpoints. I have asthma and was almost dead when I got on the plane and no one helped or gave us water or even acknowledged us. The flight was fine - the crew members are not friendly so it’s a very functional flight at best. Also my bag didn’t make it to my final destination.

Great service . Everyone is so polite and ready to help. I always was using Lufthansa but from now on I will use LOT. Thank you for your service.

Boeng Dreamliner has so tiny seats, so even medium and smaller size people have not enough room to fill comfortable..

One of the best experiences ever. Thank you to the crew.

Everything was very good. I felt that the value received in paying for Business Class tickets was very good. The entertainment offered was plentiful, but could be improved with more recent options as well. By no means a deal-breaker. The staff were awesome, in the airport, at the gate and onboard.

bus ride to the plane was very crowded and had to wait a long time to get to the plane. The flight itself was great.

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

Friendly staff, always good food , as comfortable as it can be in economy

Business class is not worth it. Not comfortable and old plane with no privacy or enough space unless you on the single seats

We didn’t fly into Neuark , because it departed without us . We ran to a closed gate , and no staff to assist, then to a customer service center that was also closed, then briskly walked (20mins) to another customer center and got a ticket , waited 2 hours , got a flight to JFK instead, because of the time delay we Ran to catch our train home , and again our luggage arrived 3 days later delivery time at 3:45 in the MORNING!!!! Crazy!!!!!! Took a few days to shake off this disappointment of your service. You’re an embarrassment to customer service .

A bellow average experience. A delayed flight , no staff to assist , running and panic to connecting flight , 2 hour wait for customer service. No luggage when we arrived , luggage delivered 3 days after at 3:45 AM !!!! Much stress and anxiety from this experience. Please repair your Brand .

My luggage was lost and I did not receive any compensation

Pleasant up to Vienna. Afterward (Vienna- Zagreb) was an horrific experience

Leg room and seat back not a good recline (middle seat)

The option to check in the carry on bag for free was very convenient. If one checked bag could be included in the ticket price that would be even better.

It was very good, ,especially the working people in the plane, they are so polite.,thank you

They never gave any meal during the flight. We’ve flown for years and then doing this now is ridiculous.

Check in was not available online. It was super long line to check in

I did not have a good experience from the first point of contact to the check in person to boarding and the comfort of the seats. I would not travel on Turkish again. I will let my family and friends know about my experience which was not a pleasant one.

Food quality and the overall service of the staff and significantly decreased. The flight was delayed at the Istanbul airport and the passengers were kept onboard for more than 3 hours. The staff didn’t kept the passengers informed and everyone was upset.

Cross Atlantic flight terrible aircraft TK10 on the way back : Old configuration tacky . The boarding in Istanbul at the gate fly TK686 was a mess unorganized , very rude ground staff . Overall never again

The food served was frozen salad and hummus. The hot meal was fine. Crew was doing bare minimum

I enjoy flying with Turkish Airlines and such good hospitality among the crew memebers

Good food and wine. Some of the Guy who are in charge to board Passengers on the plane couldn’t use the word “Please” to direct them drop their hand luggage to be loaded on Plane bcos he said the inside storage may not have enough room for all.

Turkish Airlines apparently no longer gives you 2 checked bags allowance on international flights, so that pleasure cost me $165 for my second suitcase at the airport. On top of that, they damaged that very suitcase, which happens to be a designer one and part of a set - ripped one of the four wheels right off.

Pretty standard for long haul international flying. Food was fine, tv/movie selection was great, wifi did not work at all, crew was pleasant enough.

Very poor service. Not friendly and special food ordered but not served

Had a crying baby and a toddler behind me so it was difficult to get comfortable. Searing was tight even for a relatively small person like myself (5’8” 155). Fast flight but arrived so early the gate assigned was still occupied by another plane so we had to wait for about 20-25 minutes to get reassigned to a new gate and get over there.

The check-in process is not the best They should have agents in site to help with any problem especially a rebook. Why does one have to get on the phone when there were at least 8 agents around that could have help?! Flying is stressful as it is and having someone willing to do their customer service will ease some of the stress.

I liked that the flight to Kosice was on time, the service was excellent and we arrived to Vienna early. The only thing I did not like, is that I had to pay for my suitcase $75. Bummer

The plane’s radio wasn’t working. This delayed the plane for an hour and a half. Then we all broaded and taxied down the runway only to get called back because the radio was still not working. Had to get off the plane and then find another plane making the trip 4 hours delayed. Maybe a different plane should have been chosen sooner?!?!?!

Late out of the gate, late to takeoff. No screens on plane. Uncomfortable window seat.

More water distribution throughout flight. Food quality poor and hot items delivered not hot on both attempts. Not United Standards

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Haven’t used United in a while. Was surprised with the free blanket and earphones. Service was great. Huge plane. 9/.row.

The flight was very good. Only complaint was that the usb charging connection did not work for either me or the seat next to me so we both had to use our own portable battery to charge our phones. I also liked the fact that I could purchase Wi-Fi for an hour instead of for the entire flight.

Your seats in the last 5 rows are terrible. My knees were jammed into the seat in front of me and the lady sitting there decided to recline it. Jammed my knees bad. I don’t know if I’ll fly United again.

Sorry, I’m not a fan of United. The seats are just too cramped and uncomfortable if you are traveling very far.

I am not sure I like the new Discover line of Lufthansa. I have been flying from us to Italy for the past 30 years and always favored Lufthansa ove other Companies because of cleanliness, service, food, beverage. When compared white other airlines Lufthansa was always considered one of the best. I can't say that anymore. I fly Lufthansa only because I consider the line MCO to FRA timely convenient for my schedule but always look for alternatives when before I was considering other routes only if the price was in question.

Crew and service was excellent. My seat was super small and cramped! No leg room

Staff was great. Space in bathrooms was very good. Boarding went smoothly due to aisles. I would like more room in coach. 2 more inches would be helpful. Lost luggage was a big issue; more on the administrative side than flight related, but diminished the flight experience.

Good but entertainment system was not easy and very buggy

Actual flight was smooth but we were delayed 70 minutes. Were promised to make it up to us but were given no refreshments

Flight was cancelled and I got rebooked with anther airline. Also had booked a direct flight and got a layover.

Did not fly HOU to SAT as flight was cancelled.

Very nice. Crew was excellent and our seats had great legroom which we paid extra for so I highly recommend this option when flying internationally.

Zero legroom or space in economy. Flight was delayed into Munich causing a missed connecting flight and other missed bookings. :(
