Best airline I think. No problems with anything. Crew were great, no problems with the airline food and entertainment and a smooth flight.

I was in a middle seat where I felt a bit too cramped otherwise the trip was good

Lounge a access was excellent as was the attentiveness and service from the crew as always. The food and drink supplied were of good quality. The entertainment system had a good selection and I liked the mapping system supplied. However the screen wild have been bigger and the operation a little smoother to navigate. The seats were barely comfortable, but adequate.

Headwind delayed our flight which wasn’t the airlines fault

Food from Surabaya was below average but from Singapore is much better

Horrendous. We upgraded and they took the money but cancelled one of our tickets. The recline action didn’t work on the seats for the flight from Singapore to London, pre booked meals but they seemed to have disappeared as well.. Phone customer service was horrendous. Took 5 phone calls and no fix. Craig at the airport was the only one who seemed to be able to get the ticket back.

Very good flight from Boarding to landing -efficient and comfortable with decent entertainment options

Loved the airline with the exception of their carry on limitations. They enforce a strict 7 kilo limit for carry on baggage which is ridiculous. We traveled from SFO to SIN with carry on with no difficulty yet when we checked in Delhi they forced us to check the carry on bags. The weight of our carry on bags were 11 and 12 kilos and while they exceeded the limitations set by Singapore Airlines they were well under weight limitations set by may other carriers. Interestingly my wife and I were each allowed two 22 KG bags to check in addition to the 7 kg carry on for a total weight of 102 KG's. Our total weight with the one bag we planned to check and our two carry ons was 46 kgs.

So happy I flew with Singapore Airlines. The customer service is top notch. I am terrified of flying and the staff made me feel so at ease. Will only fly Singapore internationally moving forward.

Food could have been better. Too many passengers getting up and down all the time.

The experience was efficient, on time, and provided great service.

one hour transit not good. cathay pacific is not helpful at all

Trip was fine. My only complaint was that when the passenger in front of me reclined her seat (which was, in essence, the whole flight except landing and take-off,) it was uncomfortably claustrophobic for me and very difficult for my husband to get in and out of his window seat. Also uncomfortable to watch the entertainment because the screen was right in your face.

The flight was just ok, but the vendor made it exceptio ally bard to manage my own reservation and would not give me access. The blocked all of the one time pins to come to their email address which caused me.to go through them eceryrime to get seats see rhe reservation and even get wheelchair access for my sick 71 year old uncle. They only xommunicates via a bot which gave me incorrect info. I thought this was Kayak and not underprivileged. They ruined his trip, did not get him aisle seats and made it impossible to purchase extra leg room. It was a horrible experience. He was taken to hospital on arrival only to find he had blood clots and pnemonia while trying to navigate the airport. This vendor is very irresponsible and the airline could not access his info.

There were delays at boarding and landing. These events resulted in a tight transfer time in HK. Poor signage for transfers. Finally, lost luggage at final destination.

It was good. The planes needed to be updated though, they were dated and the entertainment systems were old. Service was amazing. The pre-booked meals were lacklustre.

The morning in Hong Kong was ridiculous. Very chaotic. The flight was delayed. Missed connecting flights. Kathy should be more competent in getting the planes ready ahead of time so that flights can depart on time.. totally ridiculous and unnecessary. Very poor performance.

Flew from lax economy on cathay 777. Seat configuration 3-4-3. When the forward seat reclines it feels like someone is leaning forward and staring you. If you are slightly big tray tables will touch your abdomen even with seats upright. AVOID this above 777 configuration at all cost for a long flight. However their Airbus 350 3-3-3 configuration felt spacious and Seats wider.

It's basically 15 hours with an airline in economy class. There's really not much of anything that could have been done better unless I had a first class ticket. Cathay Pacific does excellent work, with a very professional, friendly and attentive crew. It's literally the only airline that I will fly to Southeast Asia.

Well- trained, cheerful onboard staff. Business class seating and storage were excellent. Outstanding range of food choices, though quality ranged from just OK (seasonal rice and beef dish) to outstanding ( congee and soup noodles with beef brisket). But what can you expect; it's on a plane. I couldn't figure out the remote control, but touch screen worked well. My wife and I (in our 60s), didnt find much to watch from the Entertainment choices. We mostly watched the flight maps. The bedding did the job but is unwieldy and ends up in a clump, with one-third falling on the floor.

Flight was canceled. I was not alerted. It was only kayak that alerted me

Flight was 2.5 hours late leaving. We spent 50 minutes of that sitting on the plane with no explanation. They did reduce the time in the air so we arrived a little less late which was something. The cheese and crackers were okay but the wine was terrible.

Excellent as always, I won't fly to Australia, and back to the US on any other airline. The flight crew is always top notch, and have a way to make one feel extra special. Thank you for your service, I would rate Qantas Airways a 10+.

Basic airline, aircraft and service. AA gets you from point A to B. My flight was delayed by 2 hours too.

No internet on flight, which makes log travels really hard.

Not great. The inflight entertainment was all on an app, and I did not want to watch a film on my phone. Also, the range of options of films was limited.

by the time they got to our row, they were out of some of the food options. games and movies were great but maybe more game options like tetris or pac man would be great

A few more inches of legroom is all i ask

Great as usual, some delays but well communicated and made up for in the air

Business class points redemption - good value for points paid, dubious value if out of your own pocket, domestic class business product okay for this length of flight. The flight left and arrived on time, crew were good, aircraft was a bit old and tired, but still miles ahead of their competitors in Virgin and Jetstar.

Uncoordinated boarding, seat comfort is terrible, even toilet is so small that overweight people wouldn't fit in. Baggage scam with additional fees. Stay away from this airline.

Forthright communication to the customers regarding services offered and any fees involved.

Scoot is a no frills budget airline. Do not expect a legacy airline experience.

I have taken more than 50 flights in the past year and this is the worst onboard experience that I've come across. There's always a risk with budget airlines and their creative views of customer service. Having bought a standard seat, we boarded at the assigned seat - we naturally couldn't choose ourselves as that would be extra cost. After take-off, the person in the row in front leans back their seat. As a frequent flyer, I believe this is their right, so I try to lean my seat back as well to have the same space available. However, my standard seat could not lean back, as the row behind was an exit row. As I had paid for a standard seat, not a less space than standard, I moved to the completely free row behind me. This was not allowed, as due to extra legroom, this would cost extra. Subsequently spent the next 30 mins discussing this scenario with the crew. I have no issues with budget airlines and additional charges, but if I pay for a standard seat, I want a standard seat, not one with less space. As you do not offer me a discount for the less space, do not try and charge me a premium, when I find a free seat with more space. It works both ways Scoot.

Finishes were quite worn, including our very scratched up seatback. No entertainment available, and the WiFi (even for “ScootHub”) was very slow. Crew were somewhat friendly.

Food & lower the prices. Look at Air Asia food look better & affordable

Not a frequent user of their website booking. Booked my check-in baggage and only realized that I did not book my check in baggage for return flight. The receipt was not clear in identifying that as well. Was charged exorbitantly at check in counter. Bad taste for sure when it is a business trip and not leisure trip. Baggage was delayed for more than an hour at belt back in SG.

Boarding took forever. It's also weird that we paid more (for preferred seats) to get on the plane last. Inflight WiFi never worked the entire trip. I want my money back.

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

Departure date of the ticket was ONE WEEK LATER than I purchased it for. Total failure on trying to get it reissued for the date I was to fly on. Will NOT use Kayak next time due to this screw up on Kayak's part..

On-time takeoff and arrival Cabin crew very helpful, especially the crew manager (I think) (young gentleman with glass)

I cannot check in online , and not able to select my seat

Watch for "bait and switch" - cheap prices, but not obvious at all at point of purchase that there will be an undisclosed charge for baggage - and less obvious that you will have to purchase baggage at an eye-watering level. Better still, if you go this airline, leave your gear behind and buy a complete wardrobe when you arrive in country and still be ahead. The staff were very pleasant, both at counter staff level - they were clearly unnerved by having to charge - and on board.

No entertainment service which equates them with budget airlines. But their fare are regular airline fares. Aircraft are old and seats are worn.

The crews at check in counter are not professional, they are talking and playing around. Also no entertainment on the plane

2 failed landing attemps before going to Nagoya airport for refueling. After 3 hours of taxiing, we still needed 3 attemps before a succeeded landing (after the 5th attempt finally!). In total, 11 hours inside the plane instead of 4h30, and with only a crappy piece of bread to feed us. A shame.
