Although booked meal of fruit only The crew had not received this special meal The same happened on my flight Bangkok / CAN The films are so old that best is to use own computer to watch downloads . Serve nuts but they do not warm up . Service is attentive , WC clean

Terrible. It’s like they are stuck in the dark ages. I brought a standard carry on suitcase and a back pack - I was told I could only carry on 7kg per bag - in business class, I was forced to remove articles from the suitcase and put them into my backpack! That’s the most ridiculous thing I’ve ever encountered in all my years of flying. The two bags weighed the same amount but one could not be more than 7kg. Holy cow.

They used Thai Smile plane, which is a smaller model and used to service only domestic flights; hence, the plane is small and quite compact. No entertainment on the flight. While boarding was delayed, it was done in a quick manner.

I give EVA 5 stars in every category. I enjoy this airline and it's great team of employees. I always highly recommend EVA to friends and family and everyone.

The flight was delayed going out of the gate at BKK that made it a difficult challenge to get through immigration transfer at tapei and make it to my departure on time. This appears to be a recurring issue. The flight crew and cabin crew were excellent. The food was very nice.

The boarding efficiency was good. A couple of the flight attendants did not seem in the best of moods. Overall it was a good experience.

The setting configuration of the aircraft stinks. Nobody should pay business class fares and be so uncomfortable. The design of facing fellow passengers is a brilliant nincompoop.

Entertainment is limited with a relatively old catalogue. Wi-Fi never works and the cabin and lavatory had evidence of a lot of scuff marks and temporary repairs. Nothing unsafe, but a bit tatty in places.

Delayed flight in Singapore caused the transfer at Bangkok to be very stressful. Fortunately, no elderly were in this trip, else it will not be possible to catch the connecting flight. There were also several occasions throughout the flight journey where some of the passengers were not wearing their seat belts despite several remainders from the stewardess.

USB charging port was not working at my seat 48K.

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

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
