Our flight was canceled with no rebooking offered. We are still waiting for a refund and had to book a very expensive flight to return to Toronto without any compensation or help from Turkish or flight hub. Extremely poor service during a time of crisis, speaks volumes about the type of airline and flight hub as a disaster of a company with zero accountability

Our flight was canceled with no rebooking offered. We are still waiting for a refund and had to book a very expensive flight to return to Toronto without any compensation or help from Turkish or flight hub. Extremely poor service during a time of crisis, speaks volumes about the type of airline and flight hub as a disaster of a company with zero accountability

the cabin was kept too hot. couldn't sleep as a result

The local Turkish Airlines staff in Helsinki isn’t not aware of immigration laws of Singapore and wanted to refuse even our first boarding and threatened us with deportation on our own from Singapore. We had the next connection to Istanbul and then Singapore. The airline’s online check in system is requesting the visa to download and doesn’t have any option for 96 hrs VFTF passengers. So in general we made the complaint to the airline, as the boarding experience was awful due to unprofessional staff that doesn’t check or want to check the exceptions in the global system.

It was an amazing experience. Flight crew's service, hospitality, and the food were phenomenal. I don't think I'd want to try any other airline company after this. I would definitely recommend to friends and family. Thank you Turkish Airlines !

Majority of the staff were simply awesome and very very supportive and helpful

Surprised for charged $341.00 FOR my luggage. THY opportunist, taken advantage of the people not knowing luggage must be paid.. I flew 7 months ago with Lufthansa same place to Los Angeles my family lives and work in L.A. no luggage PAYS BIG zero .. I WILL NEVER TAKE ANY FLIGHTS ✈️ FROM TURKISH AIRLINES EVER AGAIN 😒 Please Don't recommend TURKISH Airlines to nobody.. I am a retired person. With very limited S.S. check for a month..$341.00 is my kitchen expenses for at list 5 weeks i am a vegetarian salads and sandwiches.. thank you very much for your investigation asking my experience about the flight with ROTTEN Airlines 😀

Business Class pods are horrible. If you're petite, you might be able to sleep on the uncomfortable seat and bed. Crew and food are fantastic.

I have travelled many times on Turkish, but they always board at least 30-40 minutes past the stated time. If informed properly, passengers can choose to spend more time in the .lounge instead of standing around by the gate waiting to board. The new lounge at DFW was a big disappointment. The aircraft itself was a shock. In the past I have flown this sector with regular business class seating configuration of 1-2-1, The 2-3-2 seating is very disappointing after paying such high prices for tickets. The DFW to Istanbul segment was slightly better, but the Istanbul to Delhi segment was no better than premium economy. I will try to travel more on airlines which give business class passengers more value for their money.

Very Bad experience bqz I was missed my next flight.

Good overall. Seat spacing a bit tight between IST and ISB.

The luggage problem I previously mentioned was actually this flight

The flight was delayed due to snow in Frankfurt. There wasn't much information from BA or the airport, but Kayak was great and kept me informed of the delay and gate changes.

Late takeoff, but on time landing. Lost bags, 3 days to find them, still in transit to my location. Power outlets broken, Wi-Fi not working, so much for working on the long flight.

Good. For a long flight. The comfort of the seat could be better. Also, the food was « normal » plane food. Not indian plane food unfortunately! Everything else was smooth and great.

The seats were comfortable. So many empty seats allowed for stretching out and sleeping. The onboard entertainment was pretty good. The cabin crew were so kind and kept the passengers well- hydrated, and well fed.

We had American Airlines on our return and it was confusing if we were going with Aa or BA I had 2 different flight numbers and didn’t get our gate until it was boarding. So we were a bit nervous as the which it was

No WiFi. No food. 250 ml of water only drink option. No entertainment options. Extremely bare bones flight

Economy seats were good and spacious. Much better than virgin by a mile.

I was unable to board this flight because of visa changes that I was not alerted about and I’ve been unable to contact Kayak to obtain a refund / credit anything.

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.
