Very poor No information given to why we turned around.. No one at airport to help

Amazing airline accommodations. The cabins were so great. The food was very good and the flight attendants were so nice. Made a 15 hour flight seem easy.

First off, it wasn't clear that my first flight was to be operated by IndiGO. While the flight itself was fine, this meant that my whole initial check in where I would've properly verified my seating on my Qatar flight/requested an upgrade was impeded by the fact that I had to check in with IndiGO. They said I would separately have to go to Qatar counter to deal with second flight leg issues, which was impossible given how long the check in took/no time available to do so.

The boarding process was awful-the computers were down and there was no way to check in. Took extremely long, very chaotic and no guarantee our bags were even getting on the plane. I was also delayed and took away from any time i had to catch a connecting flight.

Looks like a local flight. Food was horrible. No entertainment system.

I am a big person and have back pain and swelling in my legs, so this was a challenging flight due to confined space. I didn't find the crew very friendly either. I will think twice before flying long distances with Qatar again, due to the lack of legroom.

It was little disheartening and disappointing. Although flight staff did a good job. But customer service didn’t do anything to resolve my issue.

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

Economy travel is really hard with no room to move especially when the person sitting beside you is an XL or XXL size person who if moving could hit your face

I was travelling 3.5 years after. Agree Economy is no business class but the food was mediocre. Ordered a Hindu meal, the salads were bitter . The food was really below quality and had no tast from what I had in the past. Indian Railways probably have a better quality food when compared. However the kids meal was really nice and really appreciate how they were taken care of. The restrooms were dirty .

The boarding was efficient. The entertainment system was a bit unstable but Air France has a good selection of movies.

Not consistent with the food quality (I mean taste not freshness)

Safe and stable made me sleepy and I slept and dreamt 😂😂😂😂

I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

Worst airlines either. First leg was delayed because of crew not available. My connection was missed so they booked me automatically the next day! But, impossible to get anyone on site, web site does not let me access my reservation anymore, confirmed by useless agents over the phone. My 2-leg trip with part in business class arriving at 4:10pm ends up in an awful 3-leg arriving at 9pm the next day with no way to even choose the seats and of course at the very end of the plane. I can understand problems arrive but the way Air France handle it is just unacceptable. You are on your own. Apparently getting you to your destination is the only thing they consider their duty. The customer experience and fatigue is none of their concern. And I have a status with them. I will reconsider my priorities when flying with Air France and encourage everyone to do the same.

Our flight crew were terrific. And they handle a difficult passenger with finesse.

Excellent, Lima to Paris. But Paris to Amsterdam, delayed, missed my flight and KLM treated its missed flights passengers very badly, terribly bad. No hotel accommodation given. Passengers were told to find their own hotel accommodation and claim at reasonable rate and left the booth and literally with armed Police Officers listening to passengers complains. For three hours, after moving by Uber from hotel to hotel and calling and booking online, no hotel was available. I had to return to the airport and seat/sleep on the benches, suffering the cold, and rats running around until my new allocated flight the next day. It was the most terrible KLM treatment even seen and being a Business Class passenger. Still mentally suffering to date as a result.

I don't understand the concept of paying to get your personal luggage onboard and then asked to check it in.... either sell the space or don't, its a hassle to carry those all through the airport just to make a check in at the last minute.

It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.

Old airplanes small seats expensive tickets, not as expected overall and not comfortable according to the price

Unfortunately the flight was cancelled so I never got to go

The seats seemed smaller than other business class offerings. The entertainment menu was limited. Flight crew was good.

Dear Team, I purchased a full travel package that included 2 checked bags through you and JustFly. However, when I arrived at the airport, my ticket showed 0 checked bags. Since I was traveling internationally to India with 2 bags, It was a $200 per bag at the counter, which was extremely disappointing. For an international trip, why would I ever choose a no‑bag option for only $20–$30 less? This seems like an error in the booking process, and I am requesting clarification and a resolution. I have called JustFly and on phone for 1 hr :53 min and they couldn't help till I show some kind of proof etc which isn't possible but besides that love your service and using it for years !

Awful the whole airline arrived to check baggage and board our flight and the airline desk was closed where none of the passengers could check in baggage, asked for a supervisor and was refused a supervisor, called the airlines from the airport and they refused to refund the flights for their actions in the airport, Etihad and Garuda Airlines absolutely horrible customer service all the way around.

Early arrival. Good boarding. Deplaning this flight is very slow both coming and going. Baggage arrived quickly for Pearson

Ethiad wanted to charge me $1100 for 2 checked bags on a ticket that was $550. Nother the airline or airfare assist was willing to help before arriving at the airport. All parties said it was the other responsibility to help. Never flying ethiad or using kayak again.

Dirty and smelly lavatory and toilets in Wamos Air operated flights

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

On this flight...fine. The one from India to Abu Dahbi, awful.

Kayak and Aran grant issuing business class tickets without lounge access and sometimes 1 or 2 connections in economy class. It’s very disappointing to find out that after buying the ticket. Never buy tickets on kayak and Aran grant again

The crew were kind and very helpful. Did not expect food service. Was served a warm soft sandwich bread , was delicious. Overall the service, the staff were great. Highly recommend others to try Turkish Airline

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

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

They have adopted a crazy "no paper boarding passes at all cost policy". We spent half an our at the checkin stall – my elderly mother and her grandchildren were flying. She had no phone reception for some reason (besides being an inexperienced smartphone user), the kids had dumbphones, And they still won't issue a paper boarding pass. We had to do a lengthy dance with getting the boarding pass SMS on my phone and transferring them to her phone via WiFi. This was horrible, honestly. I can't imagine how they could manage it without me being there. Trees (and airline profits) should be less important than people.

two of our bags didn't arrive - this is nonsense given we weren't connecting from anywhere and the flight wasn't full so there shouldn't have been a weight problem. Also, business class and star alliance gold, my bags should have been prioritized.

it was great honestly for the melbourne flight a kit with blindfold and slippers was probided to each passenger on the seat and the food was really great will definitely recommend people take turkish airlines for travel not just on the sin-melbourne route.

Went great, they even reopened the gate for me when I arrived late.

My, Syed Zawar Hussein Shirazi frequently flyer membership number was not included on my boarding pass from O’Hare to Istanbul despite my reminder to the attendant at check in. Further she forgot to give me my boarding pass form Istanbul to Lahore and she needs to improve her customer service, please 🙏

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.

Everything was good except that they didn’t give us seat for our connecting flight in Istanbul from Cairo. This created a panic situation. Hopefully they give all customers connecting flights seats right from the start.

The service was fabulous and the food was excellent. My luggage was left in Frankfurt due to late arrival but it is supposed to arriving on tonight’s flight.

Crew was outstanding, helpful and friendly. Food is deteriorating. The snack at the end of the flight was not good, a greasy moosh of toast cheese snd other unidentifiable ingredients. Coming from Germany a pretzl with butter would have been better. Entertainment had a great selection.

I think they overbooked Frankfurt to New York and bumped me off. This changed my return travel I arrived home about 4 hours late. Almost 24 total travel time Totally unacceptable Would not travel with United

Food could have something without dairy, I couldn't eat anything. Tv for both seats was malfunctioning. They have one bottle of ginger ale for entire plane.... and I paid extra for these seats...very disappointed

I paid extra for more comfort, didn't get any better than any other seat, tv didn't work on both seats, it'd

Stop charging for alcohol overseas flights and start taking cash again not everyone wants to pay with card if the person is bigger give him seat on the outside seats not the middle in between the people is common sense and mainly if you fly for Lufthansa provides the sam service and experience...

If the plain wait for the passenger it should wait for the baggage!!

The pasta in the evening meal was tasteless. Otherwise, the flight was okay.

Premium Economy was very comfortable. Flight staff was cheerful and helpful.

Cheapest airlines I have ever been on. I got downgraded and never got on united. I got rerouted through Vancouver onto jetwesf
