I paid for the seat and found out that the seat doesn't recline. The staff didn't help in arranging an alternative.

Turkish airline does not care if the business class senior person has to go from one terminal to another. no guidance, no trolley, I would not travel on this airline again and also tell my friends.

Amazing! One of the best kept secrets in air travel!

We fly Bussines class and we didn’t feel like it is. Out luggage didn’t arrive and we have to return again next day from our hotel to airport to get them. Still waiting. No information from Turkish airlines Very poor customer service I think booking through kayak it was wrong decision

Three screaming and crying children in business class made it very difficult to rest. The crew made no attempt to address the situation. I might as well have saved the money and flown economy. The parents were oblivious to the discomfort their children were causing. The lounge in Istanbul is wonderful, but did not make up for the misery on the flight. My business class seat power outlet was broken and I have a cpap. The crew couldn't fix it or move me to better seat. Fortunately , the passenger in front of me allowed me to plug into his power outlet.

My seat/bed broke. Flight was delayed. Most of the cabin crew were very pleasant. Amenity kit was nice. Chairs and cabin was worn. Food was mostly quite nice.

I flew Business with my daughter and son. The service, friendliness of the staff and the comfort of the fully flat beds were phenomenal. Would definitely fly Turkish again soon.

I had 2 flights on the same day ( beautiful sunny non windy day)both had a touch and go -around on the runway. My husband said they were training a co pilot. The bathrooms were stinky dirty and the the floor was sticky. On one flight I had the worst food option I have ever had on an overseas flight.

Entertainment system is okay, flight attendants were ok. Leg space very narrow, I couldn’t get what I wanted to eat, dinner nor breakfast.

Staff are friendly and the pilot when we landed very smooth.

At the Check-in desk in Constantine, I put my luggage on the belt. It wasn’t very full. The Air Algerie agent said that my luggage was too heavy, and so I had to pay money. I asked how heavy it was, and he said 20 kg. I doubt just clothes would be that heavy. So I asked how much money I had to pay. He said 12000 Dinars, which is about $150 dollars (i.e., about 150 Euros). I started objecting, saying I don’t have that much Dinars, mostly because one can’t exchange dollars or Euros for Dinars. No one would get on a flight to Paris with 150 Euros worth of Dinars. Worthless. Also, I told him the flight itself didn’t cost as much as $150, so this charge was way too high. But, the Check-in person insisted that they would no take my luggage weighing that much (20 kg). So I asked what weight it must be. He hesitated, looked upward for a few seconds, and said 10 kg. So I stepped a few feet away and transferred clothes from my luggage to my backpack, leaving my luggage feeling 1/2 the original weight - - - hopefully now only 10 kg. I went up to the Check-in desk again. The Check-in guy put my bag on the scale, and said, “You still must pay 12000 Dinars.”. I asked why, and he said my ticket did not include any luggage at all. I objected immediately, saying that I had a round-trip ticket and that Air Algerie carried my luggage from Paris to here in Constantine. Therefore my ticket must actually have included luggage going both ways, round trip. But he continued to say that, no, my ticket didn’t include luggage, and that I must pay 12000 Dinars. At that point another Air Algerie agent walked up behind me, asking what was going on. When I told him, he said, “Come with me.” He took me 30 feet away, behind a pillar. He asked how much money I had. I said $40 US dollars and 20 Euros. He looked one way and then the other way. He said, “Give me the $40 and I’ll see what I can do.” A couple minutes later he said it was all fine, and they would take my luggage. So I went back to the Check-in counter, and they took my luggage, saying, “Don’t worry, it’s all fine. Everything is fine.”

Always late , never on time people rushing to catch their connection flight , the only punctuality of air algerie is for sure they delay the flight

Air algerie flights always the same Late or canceled with poor service So , not a surprise The flight yesterday full and late with poor service as usual

3hours deleyed, absolutely horrible day.,horrible company.,bad service.,they should check the flight if it safe before letting the passengers in .. it was a technical problem ( very hot temperatures inside the flight) we had to come back and change the flight.never again with this company
