When boarding, after business class should be premium economy, but economy class already lined-up at the gate blocking premium economy to board. Singapore airline crew should done a better job to organize this chaos :( Thank you.

It seems paying premium economy does not make difference with economy. No priority boarding, not worthy paying extra$$$ for premium economy.

Wonderful service, planes and interior in great condition, very pleasant experience

The premium economy seats were not that great. It could have been more premium than economy seats.

Perfect experience from boarding through to leaving the flight, comfortable and personalised service from all staff, highly recommended

They were able to assist my elderly father and myself after not being able to check in to scoot. The counter service was phenomenal. They did what they could to get us on the next plane so we could catch our Connecting flight. Scoot closed early on us so we ended up missing our flight.

They are great with every aspect of customer service. Helped my elderly father and aided him with using the restroom.

Due to the delay of my first flight, my connecting flight with JetBlue was canceled by Singapore Airlines, but the JetBlue crew was very accommodating and rebooked a seat for me. The crew was very nice and had good attitude.

The overall operation needs to be improved. The in-flight services took forever and sometimes ran out of options.

Check in was snails pace, only 1 of the luggage screen was working so long lines, an hour to check in Nobody seemed to want to fix the issue Flight was 45 minutes late Scoot is a mini sized plane ( sardine class plane), literally felt slammed between people

Food is really bad, not to the Emirates standards. Coming out of Houston airport is very confusing,

Service needs to improve. Air hostess do not register flyers request and we need to keep on repeating our request to them on multiple occasions

The flight was great. We had to purchase extra long seats for the long flight. But overall it was great.

The experience was not as pleasant returning as leaving. Went through clearance twice, crew was not as customer focused.

WORST AIRLINE EVER—FOOD WAS MEDIOCRE AND WIDEBODY 777 BOEING WAS VERY UNCOMFORTABLE! IT WAS NOT WORTH THE MONEY THAT I PAID.

Amazing service and food. However I didn’t get chance to choose my own seat which bothered me a little.

More space all around is practically essential on long international fights, and Emirates definitely delivers. But food selection and taste was only average. Otherwise, the flight was smooth and the cabin crew service was fine.

Food was not eadable. Testless and not apealing. order for indian vegitarian, recived spice less. combination of main course and side iteams are far away from traditonal food, serve less iteams. , but eadoble. Thanks

I bought Business class ticket but they treated me like economic class. No lounge allowed at check inn I have to take stuff out while other passengers have more than 25 lb in bag. Because I bought tickets from other than airlines . It’s discriminations from airlines to passengers.

Quality and tasty Food and service, bigger seat comfort and leg room, etc.

Suddenly Flight has been change by Qatar and there’s no information is there of us from Bom to Doha and counter person is behaving like Qatar owner next I will not buy Qatar and I will not suggest anyone to fly in Qatar

The crew was fantastic and the over flight was perfect as well.

They shld provide food. Between food they are giving 10 hours gap which is toooo much

The crew was great and the food and liquor offerings were good. Seats were a bit cramped. Flight arrived early at destination. That's a plus.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

I had already opted for Vegan food before 2 months yet they say we have no record for it,

Too many boarding protocols. Never experienced with other international flights.

Polite and helpful crew. My son developed fever. Crew members came and gave him medication and also came and enquired about his health several times.

After going through security and waiting for the flight at the gate, there was no access to bathrooms and no place to charge a phone while waiting for the flight. But once I was on the plane, everything was very good.

Overall good but staff in the place looked extremely tired after 8hrs in 14 hrs journey and then service was cut short and response time for calls increased in later part of flight. Food was ok not astonishing

Very very impressed with the proactive care and alertness with which ABHISHEK Chowdhary took care of us. Quietl,dignified , very alert, and meticulous. Very impressed. Also with SUNiL Kumar who was there for us in a very helpful way. SHERLY ALEX On Flight 119, BOM TO JFK CUSTOMER ON SEAT 21C, 21ST March 2024

If you are traveling to mumbai -- must try SFO - MUM direct flight. It's a game changer when you are traveling to India. Timings are well designed, optimal and makes the travel enjoyable.

Air India needs to launch new planes. Seats are worn out, most of the plane's TV screens wasn't working, USB charging ports wasn't working as well so I can charge my phone & watch my download movies, Food was mediocre, the plane smells. How can Air India put through their customers with this bad experience? This complaint needs to get escalated to the upper management. How shameful is the upper management to improve this plane? The flight is going back & forth from NEW YORK & DELHI. Two of the big cities in the world and this is how your experience is for sitting in a plane for 12+ hrs? Get your planes fixed ASAP Air India (TATA Management do your job right).

One of my worst experiences. Nothing was working in the flight. Entertainment system was broken, seat was very uncomfortable, crew did not offer water until food was provided, lights were not working, attendant call was not working. In short everything was broken and duct taped.

Old aircraft, crew were so so. Meals were mediocre. Flight to delhi was delayed. Lounge needs update and was mediocre too.

Bathrooms were horrible and no cleaning. Announced baggage claim carousel as one but came to a different one. People were waiting

Every thing was so old…. Can’t believe they are able to charge so much for this terrible level of service will use alternate company in future for all travel needs

The food on board the flight was atrocious - tasteless, spicy as hell, and simply a hodge podge of nonsensical items of poor quality.

The crew smile nicely when you board and exit, in between they are sullen and innattentive

Air India business class flight seat is too low and very congested I am 72 years old . I had knee surgery.Bcz seat was very low and there is nothing to hold near the seat when we sr citizens are going for washroom. For sr citizens one small handle should be there so that we can hold and getup.I reached on 29 th of Jan in US but still I have pain and swelling in my knee and severe back pain .Please do the needful Thank you 🙏
