Flight attendants were awesome! Very helpful and patients. Some food were good but maybe not serving fish that kinda make the whole aircraft smell fishy. The “fried pork” was tasty but too much skin so it doesnt taste that great.

Flight attendants were awesome! Very helpful and patients. Some food were good but maybe not serving fish that kinda make the whole aircraft smell fishy. The “fried pork” was tasty but too much skin so it doesnt taste that great.

Never book through Kayak. They can offload booking to third parties that are completely horrible.

It was okay. I feel that Singapore Airlines isn't as good as it used to be but it's still not bad

It was fine. Nothing special but nothing went wrong so all good.

Overall the airline tried to give excellent service. The wheelchair service was bad at SFO. My baggage was also delayed but I thank them for taking the trouble to find it and deliver it to my home.

I felt that the whole experience went very smoothly. The aircraft was extremely clean and tidy on boarding. The cabin crew were beautifully turned out very, very efficient and were a credit to Singapore Airlines who are now my favourite carrier.

Service was very good, food and entertainment systems were good

No frills airline with minimal leg room and no entertainment

I wish there was a little more leg room between the seats. The recline was good and seats overall were comfortable. I also didn’t like the 2-4-2 configuration.

The flight arrived on time. 2×2 seating meant no one needed to sit in the middle. This was a connectibf flight from Singapore and required going to 3 counters in different levels to check a golf bag

Gate and boarding processes were handled smoothly and efficiently. Both (connecting) flights departed and arrived on time. The cabin crew seemed anxious and a bit stressed/rushed. Food service was OK, but the hot food dishes were poor quality.

HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q

We still get drinks and a snack. Love the gift bags too.

business class is old but still done very well by the team.

Excellent airline. The plane was clean and the staff were very attentive

Good experience although the boarding gate is at the terminal extension hence need to leave lounge to head over earlier.

Thai Royal First is very good. Easy check in , Private room in the first class lounge and escort from ticketing to the plane. Once on board crew was very polite, food was outstanding, and the ride was smooth as silk. Restrooms were especially clean. Great Experience

I'm not interested in improving the airline. Therefore, I won't explain this in more detail. Next time I'll try a different one.

The flight (boarding) was delayed by 40-50 minutes and there was very crowed. They need to improve on the timeliness & boarding process. (They asked passenger to board in groups, but the 2nd group was standing there waiting for 20 minutes!). However, services from the crew was very good, also the food was good as well. I also found the legroom was quite comfortable.

Need to improve on punctuality. My flight was delayed by 1 hour.

It was ok, but not what it was like 20 years ago

Great food and good entertainment options for the long flight.

It seems that qantas are trying hard to regain their status as Australia's premier airline. I only flew economy but happy with the service entertainment, food, configuration everything.

I never flew with alliance. Kayak is a joke and none of the flights or times were correct. Won’t ever use kayak again

I missed my flight due to unforeseen circumstances It was, however , an excellent price !

Loved the food and beverages available, spacious economy class, excellent entertainment

Very good overall. Highly recommend for all flying to Australia

Helpful staff when I felt unwell. Qantas need to have an audio/music channel so you can listen to various music/.artists

We had bulkhead seats in a A380 in the upper deck in seats 31 D and E. Storage was very limited other than in overhead bin - which is not within reach when in seat. Yet paying same price as others in premium economy who have a lot more storage within arm’s reach. Seems very unfair.

Good check in and helpful staff. Delayed for 1 hour. Took about 45 Mins to get baggage’s at DFW . Food was average ( Hindu meal ) . Overall it was good experience

Boarding was not as per sequence Light snacks were not available Window had hair oil stains and water condensation

3 hours delay ,we changed plane after boarding and waiting inside

Apart from the staff at the airport who were amazing the rest of the experience with scoot was disgusting a very basic flight packed and uncomfortable no consideration to a disabled traveller. And even worse from Singapore to Vienna. All about the money. Not even a complementary coffee or juice. From the airline. The staff at the airport didn't look at me as been disabled and no help not even a wheelchair was offered. The food on the plane was cheap and tasteless and expensive no entertainment on plane and WiFi which had to be paid for was intermittent at best.

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.
