I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

Awesome as always. I wish though the cabin for premium was upgraded.... Same old sane old :(

It was a great flight Food was great Crew was spectacular

Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold

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.

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.

Indigo attempts to make you pay for a seat during check in. I opted to not do this. The result - they allotted me and my minor son seats apart. In the interest of making maximum money, they seem to have lost common sense too. Similarly, even during the flight, the crew are busy trying to serve food to those who’ve already paid for it. By the time they’re done, it’s time to land and no one else is able to get anything. Sadly this seems to be what makes them profitable, customers just need to bear with it till a better airline comes along.

As usual invariably delayed Lots of time in getting chkd in baggage

Staff needs to be trained in managing customers better. Indigo appears to be a low cost airlines in all aspects.

Flight was delayed and also lots of mosquitoes on the flight

Two times the gate was changed and flight got delayed

INDIGO Never On Time & Always Prefer to Shuttle Passengers Like shuttle Corks

I did not like the communication gap existing amongst the staff and the customer. My flight to Nagpur was delayed by two and half hours but it was informed to me on email ( not by W.A. or SMS) when I have already left my home in Baner area. I was painfully detained at airport with luggage when the gate no. 10 was changed to 5. I'll never recommend your flight to anybody.

Seats don't recline, no charging points. New aircraft and very clean. Crew should serve some water atleast.

Wife and I were seated in separate seats across the aisle

There was inordinate delay without any plausible reason. This has become a normal feature of Indigo now a days.

The flight delay... but bus from the airport be on time

Bad experience, delay like no tomorrow. Original schedule departure time at 9:30pm, delayed until 12:05am only depart.

Great. Very satisfied with a direct flight from Penang back to HK international. Stewards in the cabin were very friendly and helpful. Would not hesitate to fly with Air Asia in the future.

Second time flying on AirAsia. They’re fine for a low cost carrier, so I don’t expect high level hospitality. They could have informed us that the flight would be delayed even if by a few minutes, instead of the passengers asking the gate agents why we’re not boarding 8 minutes before takeoff. And given some of the passengers on this particular flight were problematic, the crew did great handling such people.

Meh, it was AirAsia. It's not about a quality.

Great flight. Achieve my objecttive of travelling with less hassle .

They didn't have a single blanket for hire for a long haul overnight flight. This wasn't good enough even for a budget airline

Kayak shares with you the best price! and in my case it was Air Asia flight. Air Asia flight was on time, the boarding was seamless with FACES technology at KLIA2 and the pilot made a great smooth landing upon arrival. Excellent trip!

I left the city late and fortunately the flight was also delayed 50mins

Air Asia’s standard has dropped tremendously post pandemic. The whole organisation feels ‘soul-less’

The Air India lounge in Delhi , was very disappointing! The food was of poor quality and options were limited especially for vegetarians!! Beverages were fine. The in flight crew was excellent! . They helped me with my seat controls - the controls did not work without a hassle or assistance!! A very poor showing for a Business cabin!!! Post flight , the wheel chair passengers ( including Me) were “ shepherded and left waiting twice (an hour or more) before taking us to immigration! I chose to Fly Air India because I want. to patronize our National carrier with the hope that the experience will improve!!! Regrettably, I will have to look at other options for my next trip to India

Entertainment system was not working and was told I would get a voucher and have not got one. No toiletries were available not even a toothbrush false sweet talk by ground staff

Worst International flight I ever had in my whole life time. Boarding is the worst of all and flight experience was also not good. Screens were not working, seats were not comfortable and lot more.

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
