Airline reviews

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

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 😀

The staff at the boarding or the rudest uninformative and no English whatsoever they’re very rude as if they are envious of you travelling I don’t understand how could someone would be this rude and this out of touch and cold

Nothing luxury about Turkish airline compared to many other airlines

Entertainment was good. Flight was delayed, nearly missed my connecting flight. The gate was changed on several occasions. My luggage did not arrive on time and had to leave without it.

The airline could improve its business class seats and privacy in line with its competitors.

PLEASE GIVRE US PERMISSION TO BOOK SEAT NUMBER EVEN WITH FEES

The fact that my flight was cancelled and made wait for 14 Fing hours to booka flightto a neighboring country.... never again

My seat number was changed unilaterally after confirmed online checkin from widow to aisle. This applies to the Istanbul-Port louis flight. Seat was also changed for the Antalya-Istanbul flight but this was because of aircraft change, I was informed. That flight was delayed because of a technical problem with the original aircraft.

Boarding experience was a mess- both to and from Istanbul airport. No one knew anything. They asked everyone to line up according to their sit numbers- it was unbelievable. Business class had a separate line, but it was hard to find- I had to go through all that mess before finding it. Would not recommend

Crew could have been more helpful in helping to find location to store luggage in overhead bins in order to expedite seating. Seating was cramped and uncomfortable.. Other than that it was a standard flight.

How about changing the personal out to more friendly human beings? This team was pretty arrogant. No fun!!

1. One of the crew who was managing the crowd in the business class line specifically asked me if I am travelling by business class while I was standing in the business class designated line. She specifically was asking only me and no one else. Seemed to imply that I may not be aware of it and may be I don't belong there?(Based on my color?) 2. The business class seats in the aircraft was average regular economy seats with middle seat kept free.

Boarding procedure should have the crew and personnel who are more trained, in a sense of precisely knowing what can be done and what cannot. They do not have the exact information on what you should do in the first place, also the boarding itself was slightly delayed due to the aircraft "not being ready".

Food was poor quality and the screens for entertainment didn’t work properly

The male attendant has zero personality. It seemed like he was over worked or hated his job, not once did he smile or made any contact with the people on the plane. Strictly business and call it a day!

Everything was really great just The aircraft was too old and sounded it will break during takeoff

Our seat numbers took a long time to be given to us. We were not seated together and I was put in the middle seat with both people on either side of me taking too much space!

The crew was fantastic. They were always there when we needed them. No wifi on an 11 hour flight was a bummer. The entertainment onboard was boring.

Our flights were severely delayed, then canceled and we had to fly out next day with no sleep accommodation help. This led to our baggage being lost and the service reps after baggage couldn’t be bothered to help. They kept sending us to different counters when we were at the right counter to begin with. The only saving grace was the angel woman supervisor with blond hair who helped us put in a missing baggage claim.
