Much better seats on Airbus 321. Food prices are very reasonable.

Much better seats on Airbus 321. Food prices are very reasonable.

My flight BKK–SHJ–TBS was changed, and I was notified only by an email that went into my spam folder. I found out only 1 day before the flight when I checked in online. The new flight had a 15-hour layover in SHJ and arrived in TBS 1 day later than my original plan. I needed to adjust my plan urgently and lost the cost of one hotel night because the free cancellation period was over.

I needed to adjust the plan urgently and lost the cost of one hotel night because the free cancellation period was over.

The flight was slightly delayed because of change of plane but informed beforehand. Flight was very good and comfortable

Superb like always. On time and quite comfortable. Only thing is that the arrival movement was by bus.

We were boarded by bus. That was a bit of pain.

No entertainment except on app. No outlets working to charge. Good service

Dirty and smelly lavatory and toilets in Wamos Air operated flights

It was great! Kept the time. Provided what was promised

The crew could have been more friendly and could have offered to make the beds. Also, Ethiad should have more vegetarian food options.

It was mediocre. Honestly, the flight was late but that didn’t bother me as I had plenty of time. The only thing that bothered me is that the crew never asked to make the beds for us in business class. Maybe the crew was exhausted and that just didn’t occur to them.

From the start of my vacation at Logan Airport, Boston it was chaotic. I'm praying my flight home is better .I'm grateful that we landed safe

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

I booked and paid for a Business Class seat for myself and my wife. 4 hours before the flight i get a call saying the plane they sent doesn't have the correct layout to accommodate all the business class seats they sold me 3 months earlier at a premium of $1500 a ticket. So they have to bump me from Business to Economy and will give me a $400 credit (total of $800 for both seats) that I could turn in at Abu Dahbi for $400 in US cash. They then promised a row that we could have to ourselves and the arm rests would go up so we could spread out for each of us. My wife was taken care of but I was put in the exit row with the flight attendents set as part of the three...and the arm rest did not go up. When we got to Abu Dahbi, they would not exchange our credit for cash as promised. Very disappointed they took my money 3 months ago and refused to reimburse for the change in seats or follow the promises made.

There was not any issues with the Etihad Airways. Staff was excellent and I love the variety of movies and games that they provided.

Was so disappointing. Business class with no TV, uncomfortable seats. Had much higher expectations.

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

Excellent staff despite some trying passenger situations. Very impressed with their good attitudes and kindness.

Awful experience in Indigo, check in lines were very long with inadequate staffing. Had to wait in a warm stuffy plane on the tarmac as the flight was delayed.

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.

Crew were unfriendly, touch screen for movies didn't work very well, seats were tight and uncomfortable

It was disapointing during the wait in Cancun. It took several hours to clean and they told us during that time we could not stand, use the bathroom, have service etc.

I was asked window seat on check in in Dar-es-Salaam. The person on the deck told me "yes, no problem", but gave me 10e and 25b seats! Better just to say "no"

Turkish Airlines inflight crew was very good, however the ground crew was not very helpful. I had booked a wheelchair for my mother from Islamabad and she received the service there, but then there was no chair on arrival at Istanbul. The wheelchair crew said that they declined to take any person without a reservation and declined to help with the arrangement of a reservation. I had to use the airport buggy system to transport my mother who has limited mobility and needs a wheelchair. It was very disappointing and I hope they can provide manual wheelchair access to the public by a need basis, as sometimes there is a mix up or technical fault in the completion of the process, as it was in our case. Also, there can be an emergent need for passengers if they have illnesses like hypertension or diabetes. My mother has both hypertension and diabetes and has residual weakness after a stroke, therefore, she needs assistance. I hope that this text will be taken seriously and the administration makes the necessary changes. Thanks.

The crew is not focused on the guests but on their task!! No extra service. No business class amenities provided. A crew is not friendly if you ask for something extra, like tea. It takes 30 minutes, and you have to go them 3 reminders. Lack of friendliness, less but more of let me finish and go back to their group and Talk. Like a passenger is in on there way. So get your I gave you food just shut up

After arriving in Istanbul, the transit information on the electronic board showed a tight departure time, and the gate changed in the middle, making it difficult to make it on time.

Food is terrible, service is not good. Staff were not personable and rushed food service.

The onboarding was extremely confusing. Had to climb the stairs to plan from tarmac with carryon bags in hand. No apologies for inconvenience. Overall not quite pleasant experience.

Boarding /lounge :Chaotic boarding , business /first class had a dedicated line but it was upto to the passenger to figure out and use those lines .Oasis lounge is clean but tiny so it felt over crowded . Neither the food nor amenities felt business/first class . Cabin and tech : 2-2-2 configuration needs to go . Leg space is cramped , headsets didn’t work . WIFI does exist or didn’t work on the entire 20 hour journey . Food and crew : Preordered “Hindu Non vegetarian” meal , crew was clueless , they didn’t even bother to ask if they weren’t sure what that meant . Served mediocre vegetarian food though menu had chicken /lamb options . In short , worst business class experience of all the airlines I flew to date . Not sure if there is one area they compete in let alone excel … avoid if you can .

Food was not available in the middle of the trip that is 13 hours

Everything was good and no points to complain. Food is always a tricky concept. Sometimes you like it and sometimes you don’t. Food was redundant from Kuwait City to NY-JFK.

Beautiful Flight took off on time and everything was good

Next time im going to use Kuwait air lines, hopefully

Comfortable seats. Be aware there is no alcohol on this airline.

Seats were comfortable. Be aware there is no alcohol on this airline.

Every thing was very food except the meal. It was a sandwich of something like a beef kebab. It was really bad in terms of hardness as well as taste. We were a family of 7 persons non of us could eat it his sandwich. Cake was good.

Screens should work, Seating need to be comfortable, Luggage management was worse. Took 2 hours to get my luggage

Flight was delayed 110 mins.. Crew on Ground or in Air had no regrets.. No apologies... Very poor boarding process... Awful food and beverage choice.

Flight was delayed and due to this we almost miss the connection flight

The flight was delayed by 3 hours, causing me to miss my connecting international flight. I then had to wait in the airport 18 hours for the next flight. The reason for the delay was a computer issue, not something outside of their control like weather. To add insult to injury, instead of trying to expedite the flight to make up for lost time, they ran a carry-on baggage check to verify every bag onboard belonged to someone on the plane, which took another 20 minutes.

झूठा है इंडिगो फ्लाइट में मील दिया नहीं जब शिकायत किया तो बोला आपको मिल चुका है

It took a lot of time to declare that the flight gonna be cancelled ☹️ very disappointed.

They denied my meal which was included in ticket and also damaged my bag completely and broke the wheel and still not accepting their fault

As budget airline everything was good. Except that - boarding process can be more organised. Then if entertainment systems are not operational. Its better to keep them switch off.

Flight cancelled after 4+ hour delay. Indigo created a nightmare scenario and showed the most callus attitude towards the passengers I will refer to them was IndiNoGo!

Very nice and pleasant. Boarding was quick and the crew were responsive
