Airline reviews

Food was surprisingly good for airplane, crew was great, though announcements were sometimes hard to hear. Plane was nice (had great headroom, large screens and big dimmable windows). But seats were uncomfortable in economy (seat width was fine, but not enough shoulder room). I wish I could use my person Bluetooth headphones with screen( I think I could mirror it on my device, but didn’t want to keep tray table down to hold it up).

If I had a chance to rate Turkish airline in negative I will definitely give -100. Worst non professional attitude of ground staff at Istanbul. If I was a owner of Turkish airline I would definitely fire all check-in staff who was on duty for this flight. Rude attitude to all customers. Non availability of food options. Chicken and fish option was finished within 8 rows and only pasta was available (seat rows 25- last row). Seat Front glove boxes were ripped and all stuff was dropping on floor. Flight crew was trying to pacify the customers but this is sole responsibility of the manager who arranged / booked the food for this flight. He must be removed from this position as he has no idea about his job. It was worst flight during my whole life. Never booking again on Turkish airline.

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

Crew attendants attention to the travelers. Good food. I always fly with Turkish Airlines

Tv didn’t work and left the gate late but everything else was perfect.

Again poor use of old aircraft and old business class seats that show there age.

Service and food were very good, I liked it a lot. I liked the little gifts we all got , but I don’t think I’d fly on Turkish airlines to go to New York from Istanbul or from New York to Instanbul anymore. Flight is way too long.

The crew was awesome. My husband fell while traveling to the WC and got a head abrasion. The crew helped him greatly and a physician that was also on the flight checked him out as well. They all get an A+!

Same as before boarding process and lack of crew experience in the process

Excellent service. Made United 's business class look like a cattle car

awesome team work seen since on board till off plane in my destination. thanks you so much.

They did not have free WIFI and I was not okay with that!

Great, except the canon was so cold. Even the flight attendants put jackets on

I missed the flight due to maintenance issues. This is the second flight I’ve missed in four days because United allows such little time between layovers. Very disappointing

It was serviceable, nothing special but nothing awful on this leg.

The back to back mechanical delays from Denver to San Diego and then on my return flight from Denver to Great Falls it added extra time both ways

The website check in was poor. Baggage fees were in US dollars but registered in Canadian dollars. The site would not accept my credit card. Scanning the passport was the worst. Someone from United needs to try the process. I’m not a novice with tech and I have to say this was a bad experience. Everything else was great.

Flight was late, the only reason I almost missed my flight was that my connection was also late.

Lufthansa seats were much more comfortable than United. While they had about the same video selection, Lufthansa didn't put advertisements in with the movies like United did. And the Lufthansa food was much better than United.

We flew business fares. Was amazing. However, the check in didn't offer business fares preboarding which is less hectic. 8/10 due to this. Staff compared to Canadian carriers go above and beyond. Would gladly fly United again.

Everything about the flight was excellent except for the fact that we had to wait one hour on the tar app and then I had to race to catch my connecting flight with the next stop

Way too crampled. Charge more and put in less seats.

This was the worst flight of my life. Economy seat directly behind a premium economy seat with extra recline meant I have about 6 inches between my face and their chair. My seat would not recline at all. I couldn't even use my laptop on the tray table because I had so little room. I was in a casket basically for 10 hours. Completely unacceptable.

I liked the flight, the attendants, and the comfort. But the gate for boarding was poor. Even the elderly had to climb down many many steps to the bus and climb up to the plane.

Service was excellent. Flight was only about half full, which meant we had tons of room to stretch out. Boarding area was nice and well organized, flight attendants were super friendly and attentive and we loved the 3 snacks!

Lufthansa is turning into a budget airline. On transfers, the luggage never arrives if you have less than 2 hours for the transfer. This is happened to me multiple times when I end up on flights serviced by Lufthansa. The first leg of the flight was serviced by Discover Airlines. It was a 3-hour flight and they only offer a glass of water. Everything else is for purchase. I purchased my ticket as economy which should have included a bag but it ended up booking as economy light so I had to pay for a bag in each direction.

The food that was served was superb!!! Awesome snacks!!! Frequent drink service!!! To me, this was shocking. I took a British Airways flight from Denver to London for the first leg of my trip and the food was horrendous. Thank you for keeping us fed and satiated on such a long flight!!!!

It was freezing. I asked crew member for a blanket and was told it might be in front of plane but I never got one. I turned off all the vents but still froze.

My flight was delayed d the gate was never updated inside the terminal. If I hadn’t checked my email I would have missed my flight. Also, I paid a total of $5100 for my flight to be. Business or first class. My final leg of my flight from Heathrow to Frankfurt was not to standard of what I expected or experienced in the previous legs of my trip.

I think it was a United A380 plane. The trip from Munich to Denver was about 12 hours and the preferred economy seat I paid $75 for was very cramped. The crew was nice but I was so uncomfortable and getting up to walk around didn’t really help. My legs were swollen for 4 days afterward. I would think on such a long trip the seats would have more room. I would have gone 1st class but it was 3-4 times more expensive. I won’t fly anywhere far away again. My last experience with Lufthansa was great to Italy and back, but this time I could swear everything was United and not good.
