Rude staff. I would avoid using the word racist but definitely partially or discriminatory. My 72 yrs old mother who is also disabled was traveling on this flight. She was the second passenger boarded to the plane. The First elderly couple ahead of my mother were allowed to use the airplane bathroom but my mother was denied entry stating it was for safety reasons. My mother objected the the couple in front of her were allowed but hostess still stated that due to the flight safety reasons she can’t use it. Even my mother explained that he is using blood pressure medication that’s why she have to use the restroom frequently but the crew continued arguing her. At one point the Mae attendent even suggested that if that’s the case my mother can urinate in her seat. The level of disrespect against an elderly lady is beyond my comprehension. This matter will be taken to the social media to shame the employees involved.

my experience was great with Turkish airlines . the problem i encountered was with kayak booking. When I booked . it showed that im allowed a bag . and when I got to the airport, i had to pay $165 for one bag.

Not up to Business Class standards. Two of the three toilets were out of order. The hostesses were aware and didn’t show any responsible act to do something. Food quality was not what we expect from Turkish hospitality. Overall we were not impressed and disappointed.

During mid flight, try to get a flight attendant to help I couldn’t find one Otherwise, everything was perfect

I was not given basinett seat.The connecting flight was missed due to airline fault i was not accomodated for hotel.Drinks were normt served frewuently.Never travelling again on tirkish airlines.I always travel wiyh family by turkish airline but no more.zero stars

The crew were very hospitable and pleasant. The food was pretty good. Unfortunately, there was a flight delay of more than 2 hours. We're not sure why but it appeared to be outside the control of Turkish Airlines.

Bough tickets with luggage, but made me pay at Airport as well

The economy seat was so uncomfortable, had not enough leg room for 13 hours flight, front seat basket was broken and couldn’t hold anything, food quality was horrible( we got food poisoned ) we charged for logged which used to be free. We paid too much for this flight and very disappointed. Turkish air line better to make satisfy and respect people instead of find different way to scam people.

This is really the rating of two flights. JFK to IST then IST to NQZ. New York to Istanbul was good. Good crew and all positives. The flight to Astana was so bad that brought it all down. Crew was nonexistent above the minimum, seats were cramped, and it was hot on the plane. Turkish Airlines seems to be slipping down to US based carriers level.

The 2 agents on the check in counter were super nice , helpful and very polite. Boarding was like a 1 2 3, I would recommend Turkish airlines for your next trip.

Too cramped up for the better seats I paid for.

I didn’t like my seat in my return flight from Montreal to Orlando at all; considering I paid extra for better seats. That middle seat was cramped up way too much.

Suitcase didn’t arrive to Stockholm. Chairs y comfy and not even water is offered

Bad baggage and people management at boarding forcing me to dispatch my bad despite being the perfect size and respecting everything perfectly, whereas many did not and many free empty spots on the plane as usual… making me loose time and my planned bus at arrival to go to Geneva. Costing me 100 euros extra! So Brussels airlines needs to refund me

I never board the flight. My visa was delayed and when I tried calling Kayak, no one answer and I still have not heard from anyone.

All great. Very efficient. Good emails that kept us in the know

Original flight was canceled, booked another one and find out when checking I was on the waiting list. Horrible experience

Actually this is my first time using airline I was in every single thing that happened throughout our journey, the appearance of the plane inside furnished about the seating the flight attendants and many many more I was so excited throughout thank you Brussels Airlines for the great service.

On board service was decent. I like the legroom at UA that seems to be more than in other airlines

It was really good because the employees were very nice and fun to talk to. The entertainment was nice because they had plenty of movies to watch.

They only gave us 30 minutes to make an international connecting flight. We didn’t make the connection but they did do a good job rebooking us despite the chaos. Our bags didn’t make it back and their process for customer support is pretty bad when it comes to luggage.

My recent experience with ASKY Airlines was disappointing. The check-in process was disorganized, and I was provided with inaccurate information regarding baggage requirements, resulting in unforeseen expenses. Additionally, the ground staff demonstrated a lack of professionalism and appeared insufficiently trained to handle passenger needs effectively. Regrettably, this initial encounter has left me reluctant to consider future travel with the airline.

The Boeing 737 MAX on this route, flown in the middle of the night, is an UTTER FAILURE for business travellers. The whole point of business travel is to arrive alert and recover from travel quickly, and this little aeroplane with its quarter recline uncomfortable business seats does nothing for that. It’s a small step up from economy in that you have decent legroom, but that’s it. Absolute margin at the cost of the traveller.

The food was terrible and the seating was uncomfortable, but the airline did a great thing letting us board in Abbis Ababa on our connecting flight after our original flight was very delayed.

It was an old aircraft, stiff seats almost wooden chairs with thin cushions. Food was ok.

Traveling with Ethiopian is always a good experience. I also enjoy the stay at skylight hotel in Addis

The flight is packed and it feels like the space per individual has gotten smaller. Excruciating for a 14hr flight.

Lost suite case and pillow that’s used by senior and they didn’t leave it at the airport

I had a comfortable seat that makes my trip wonderful. I appreciate the Ethiopia crew, they were very helpful

The hygiene was super bad. Smells bad and air refreshment is highly advisable. The crew made some one else sit in my spot and no one is checking seat number and people are jumping to sit on other people’s allocated seat.
