This flight was 16 hours and they made it very tolerable. Seats were comfortable and the staff very accommodating. I had plenty of inflight entertainment. Food was very good.

This flight was 16 hours and they made it very tolerable. Seats were comfortable and the staff very accommodating. I had plenty of inflight entertainment. Food was very good.

They made 22 hours aboard aircraft very enjoyable. I was very impressed with the attention to detail and level of service. Singapore airline will be my preferred choice going forward.

Service excellent would chose Singapore airlines as my first choice

The staff were amazing and very kind. The seats recline a little too far back and are up close when sitting behind.

My groups frequent flyer star allianceUnited airline miles was not accepted. The Singapore premium economy bag had to be requested, it was very lacking- no toothbrush. I paid more than double than economy but could only use the bathrooms sharing with economy which was hardly available and had to wait in line. Is the 2X $ worth it just for a larger seat???? It is questionable. Seats were not that comfortable. My husband’s seat had white stains on it- had to wipe it down. Our headphones did not have covers on it. Food- way too much.

The booking experience was bad. Our six character booking ID number disappeared the day before the flight, We could not find out what happened or what was the status of our flight, scheduled for the next day. We finally found the right number to contact Singapore Airlines on the matter (not easy). The Singapore agent worked through the issue in a little over thirty minutes on the phone, the day before the flight. That was great. I'm very happy with Singapore Airlines and their performance. Contact with a competent person on the matter was near impossible. It seems no one in business these days wants to deal with customers once they've pocketed the money. There were resellers, including Kayak, involved in the chain. When we finally got through to Underpricer, we did get a return call that could have proved helpful. But by that time the matter had been resolved by the Singapore agent. Majestic Vacations, the reseller who received the payment was less than worthless. That's just a fast buck operation. Ugh.

Could not really fault anything. We had a really short time between flights (about 45 mins), and had to get across the other side of the terminal. But we made it and crew were helpful. Food was good and service for the kids was great.

On time, friendly staff and decent food. Would definitely recommend.

A 16 hour flight from Singapore to Los Angeles had only 2 meals. Please make it 3 meals.

Once again the meal served was delicious - we got chicken rice

bad… no veg food was provided eventhough i pre ordered special meal

Excellent service provided the flight crew. Food and drinks were very good.

Cathay has a great reputation, though it's baseline economy seating is nothing to write home about (and SE Asia flight passengers sometime lack 'routine stateside' etiquette). On the other hand, food was great, flight attendants were nice, and price was very good~

The crews were smiling all the time with soft tunes when they spoke; the food was excellent. Thank you!

Cathay flight was fine, Amsterdam airport was a nightmare, spent way too much time walking to our next connection, no travelators.

They charged me $900 to board my flight I already paid for just because I missed my previous flight. I do not recommend this airline by any means.

Not good. Small seats. Not enough food that customers wanted. No special requests were given that i could see. Slow response from flight attendants

For a transpacific flight, flying economy is awful! The seats are cramped and its meant for petite folks! Good luck if you have long legs. BOARDING - AWFUL, we got to Hong Kong - the gate was listed, but upon arrival, there was a MESS of boarding procedures, they basically DIY'ed how to board but making three lines and putting three ground crew to check for passports in the terminal area. THEN to make it worse, after going through that cattle process, all of a sudden you see people standing and looking confused, apparently we were told to get in line to board, but the AV notification wasnt even working. So people started cramming in line - worse than cattle. One saving point, the flight crew forgot to serve me dinner and after waiting for it, I fell asleep since this was a midnight flight. After letting a crew know that I was forgotten, all of my meals were served first !!! Yay for being in the economy seats! Nothing much to write home about once more!

Bathroom was not cleaned as often as other airlines does. It was gross for a less than full flight capacity.

Rarely saw a flight attendant. Never received what I wanted from drink service. Twice I was told they would return with my order. I never saw the flight attendant again. I has requested a Moslem meal. I did not receive. It

nothing to complain about w/the food, and professionalism of the crew. i just cant stand being on a flight for that long of a time.

Everything was great from the staff to the seats and food. The plane was timely taking off and landing.. I couldn't have asked for a better experience (especially on such a long flight)

Good communication regarding any updates time of flight and flight delayed. The fight was delayed by two and half hours at eleventh hour. That was unexpected, especially when you international passenger.

The service was excellent. The quarters were a little cramped in Economy, and we had to exist there for 18 hours.

It was very nice. I will try to fly with Qantas whenever I can.

Terrible. 6 hour delay with no explanations and only 15 dollars in food credits. A disaster. I'll just leave it at that.

We lucked out. The passenger who was supposed to be in our row changed her seat, so my husband and I had 3 seats for the 2 of us. We were able to stretch out a little which made the trip much more tolerable.

We paid for business class seats for the comfort that comes with that but couldn’t use the bathroom as it was full all the time.

Flight was cancelled about 1.5 hours before departure. Replacement flight provided scheduled 1 hour later. Late boarding, late departure and arrived Melbourne nearly 2 hours after originally scheduled.

Flight is overpriced. Quality of service is poor. Constant delays. This flight again was multiple times delayed. The relaxed and careless attitude of staff is appalling. People are busy and it does matter if we do things more efficiently than chilled out. Once the flight was ready to depart we had more delays due to the careless approach of boarding passengers. Food is highly processed with limited options and super unhealthy. Leg room is shockingly bad. Even the biz class is pretty bad. Coupled with the horrendous prices Qantas only benefits given Australia is their home market. Otherwise they are not competitive at all.

The crew were great. The seat was older than an old Holden with a big metal bar sticking right into my back. The passenger next to me complained that hers was the same. The pre purchase system for food was disappointing as the pie/quiche took 20 mins to warm up, arrived too hot and with no utensils. It was one of the most uncomfortable flights I've ever been on.

Not very good, no food and not drink ( caffe or tea). Never ever fly with jet star.

Fabulous I have no issues with JetStar great service always use them to fly

Flight was as expected - we got what we paid for which was a base fare

Unaware of charge for carry on until i got to gate

I got what I paid for - flight was clean, staff were friendly

I like that fare is cheap but because there's no amenities whatsoever. You get what you paid for.

There's a reason why fare is cheap, no amenities.

It is what it is - nothing more, nothing less. No entertainment onboard but one kinda knows that when buying a ticket on a no frills airline. I choose Jetstar only because of price.

Plane was delayed both on arrival to Sydney and departure. We boarded the plane while it was in the process of being refuelled, which I am certain is against CASA regulations. Comfort for anyone over 6 foot is non existent.

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

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.
