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

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

There was no USB plug in my section of the plane. So I could not charge my phone. Also, there was no screen to watch movie or anything like that. Wish I had known that in advance, I would’ve brought my iPad.

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.

Best part: It’s operated by All Nippon Airways. It’s quite literally comfortable, reliable and respected from boarding to landing each and every time. It’s perfection without extremity in lavishness — it’s how flying should always be!

The flight attendants were unhelpful. It was a packed flight, and usually a flight attendant would help find a spot in the bin for your carry on or shift things around. Neither made any effort to do so. Also, I had to then check my bag. I was told it would be on the carousel in YYZ, but it came up on the jetway. So lucky I saw others standing around for their bags. I would have walked straight past this and on to the carousel. They could have at least told me that they had given me wrong information. Very unsatisfactory.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

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.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

Seats are smaller and harder than other airlines we have travels with. Food was edible but no good. The sandwich was the only thing I would eat again. They did have a lot of movies to watch.

boarding was uneventful. Snack was pathetic. A tiny fruit bar. Entertainment was limited to just select movies on your own tablet or phone. No live TV. I recently flew Jetblue and they had unlimited snacks and live satellite TV the entire flight. My seat was an exit seat, 20A. It was super uncomfortable. It felt cramped and the middle seat was taken up by a large woman who pushed into my shoulder and arm. Horrible flight.

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

No food just water No entertainment possibilities. No jacks to charge phone or anything

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.
