Singapore Airlines from Mumbai was late, we were rerouted to Copenhagen and then to Los Angeles. As senior citizens, we should have been given a hotel voucher for a night and fly out the next day. I hope Singapore Airlines should give us a credit in good faith if they want us to fly with them. I doubt it, but you never know.

Singapore Airlines from Mumbai was late, we were rerouted to Copenhagen and then to Los Angeles. As senior citizens, we should have been given a hotel voucher for a night and fly out the next day. I hope Singapore Airlines should give us a credit in good faith if they want us to fly with them. I doubt it, but you never know.

I loved the comfort of the flight and the hospitality of the flight attendants!

I had to change a flight date and it cost me $800.00 dollars. In the past, if there was room on the flight(which there was), Singapore Airlines simply re-booked me. This might have occurred because the office in Bali where I could interface with a human face to face is now closed since COVID. I naively figured the ability to change my flight into my decision to go with Singapore Airlines as it does cost a bit more. I will still fly on them as they are superior to the other carriers by a fairly large margin, especially for my needs.

I was traveling with my 3 minor children, one leg I was seated two aisles behind them. On the longest leg I would have preferred sitting across the aisle from them, not behind. My youngest is 4yos. I understand airplane seating configurations are not the airlines problem but seating the one adult with a reservation apart from the minors was very difficult.

plus: service and personal assistance minus: online check-in did not work

My overall experience with Singapore Airlines is great. Will definitely fly Singapore airline again.

Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

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

I requested an aisle seat and got a middle seat The flight gate was changed and the flight was delayed

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

Wanted different plane design with an additional bathroom at the back of the plane.

The crew staffs are very nice. The temperature is too low.

I booked Flexi ticket, Paid extra for extra legroom seat. What I got was worst ever place to sit. It was an emergency exit seat with lots of legroom but half of the seat was occupied with aircraft body. Means you don’t keep that seat where a passenger can’t sit. The seats are too narrow. Whole night I was awake. Not movable armrests. One of the worst.

Bad experience. Departure time delayed from 1610 to 1740. After the flight was pushed back, pilot said there was a technical issue on the aircraft and we couldn’t take off. Delayed another hour to solve it.

Great, the flight attendants were very friendly and the food was also good.

Very comfortable Prem economy seats for a long haul flight. Had a problem with the tv that the crew fixed so was great!

While I was in great pain, the seat was sufficiently comfortable to allow me to rest and not be in so much pain.

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.

My seat was sold off to someone else. Had to wait 9 hours to catch the next filght. Definitely will never use Cathay Pacific again. Bad, very bad airline. will comment on google reviews too.

One of the worst flight in business class by qatar airways and I’m no stranger with qatar airways businesses class, I travelled with the extensively in the past 12 years

Plane a little late departing, but not an issue. The pilots humour when he said “I will try to make up some time…. I know a few short cuts to Adelaide” made the passengers chuckle. This is what makes Qantas “Australian”.

I have never had a problem with flying Qantas, so this flight was the same as any other.

After British Airways cancelled my London to Sydney and Virgin Australia refused to refund, there was no ways I would try Virgin Australia again, so it was Qantas - what a good flight experience. So much easier to get off an international flight and get a local flight without having to add extra amounts for baggage

The flight was delayed by 1.5 hours and most of the flights bags were not on the flight. Have also had no communication from QANTAS

I was thrilled with the bottle of water, blanket, pillow, earphones, and little packet of toothbrush, toothpaste, earplugs. I was very satisfied with the meals and snacks and drinks. I alao was very grateful to have a seat that backs up against the lavatory, as it made it very easy to get to the bathroom without being jumped in line, as so often happens in the airplane. Of course that was just a random strike of luck, but it really made a difference.

Food was great. Customer Service not so much! Flight Delays.

The plane was delayed about 3 hours so anything else is immaterial

It was so hot on the plane mixed with being quite turbulent and a rough landing. We all felt very nauseous for hours afterwards. Crew were lovely though.

For a long haul, the flight was good. We left an hour late due to a seat in business class not working. But they made up time and we still got in on time or even early thanks to tailwinds. The crew was friendly. The meals were okay, nothing special.

Internet on internation flights is a basic comodity. Very disappointed. Same entertainment that has been on for the past year. Update your content for frequent flyers

This was the most horrific experience we have ever had. I would advise people to steer clear of this airline at all costs.

Online checkin was a nightmare. They kept popping me into Chinese language site which I can't understand.

The flight take-off was delayed which was fine but the staff seemed pretty over their jobs. The seats are very uncomfortable and the food was pretty average. Overall is was okay.

Note that food has to be purchased in flight. No free food. And no entertainment in flight. So I’ve treated these two items as okay which, in this case, means neutral/not applicable.

My Dad needed assistance to board the plane. The Jetstar staff were excellent with him and made the experience a lot easier😁

No food taken so can't rate also no entertainment so can't rate.

Would be better if can provide small free snacks on a long flight

Boarding was easy and unstressful, though the early "final call" was a bit off-putting. The crew were pleasant, and the seats were comfortable. The prices for food and drink were reasonable, apart from tea and coffee, where simple percolated coffee was charged at espresso prices. Deboarding was OK, though some Jetstar passengers appear to have a bad habit of pushing forward from their assigned rows, making it more difficult to get out for passengers that have paid a premium to sit up-front. Jetstar might want to look to address this to stop it from spreading.

I was allocated an exit row seat and was told to move so it could be given away to someone who had purchased two extra legroom seats and one regular seat but wanted the three to sit together. I was also charged for entertainment after booking but before checking in, and the ground crew couldn't do anything about refunding it. When the whole plane was given access to the entertainment as an apology for the flight being four hours late, I was told they couldn't do anything about that either, so I was charged for something I didn't want even though it would have been free anyway

I got to the airport earlier than I expected, and they let me change to an earlier flight with no trouble.

The cosmetic condition was pretty run down. The carpets were badly worn out. Even the paint on the wings was chipped and peeled! Looks like they are running these 787s to the ground..

WiFi didn’t work on both sectors so made killing time harder - planes clean modern and good flight crew - would do again if WiFi works

6hrs fly they dont give you a glass of water from seoul to singapore need to buy drink and food plus they charge for bag on international fly is always Free 1 bag from seoul to singapore is Not a local fly you are traveling true asia same story from singapore to Bali no water drink after payment for bag drink cost more the regular airline Well never use this company again we use regular company like Delta korea japan China and even scoot parent company Singapore Air

We had 2 attempts to land at Singapore Changing during a thunderstorm. Everything was delayed by 1 hour plus.

Boarding was not accordingly after front seat, bmf then back seat. This delayed for at least 40mins or more. The staff at Jakarta can do better. Is chaos at the entry to board the plane. This tarnished Scoot reputation when everyone was talking about it.

The crew was not customer oriented at all, even confrontational . The aircraft needs more attention to detail as far as comfort, and the 1 hour sitting at the gate with no air is inexcusable

We flew on the 787 Dreamliner direct to main gate at KLIA2, quick entry via eGate and on the train 41mins after touchdown. Go well SCOOT

Was on scoot plus. The only good thing about the flight was the spacious seats. Tables and armrests were extremely dirty Food: bad Entertainment: non existent Wifi: unable to connect, then was painfully slow that we couldn’t even send messages Good thing we had a night flight, so we just slept throughout.

Not clear why boarding passes could only be issued at the counter and not through the kiosk. I had already check-in on the web, so waiting to obtain a boarding pass 1.5 hours before the actual flight defeats the purpose of early web check-in.

no charging point. food offering is limited and very much on the budget line. Overall is not satisfying for such a price and duration of flight.
