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

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.

Except that our flight was cancelled, by mail, and later moved to 12 hours prior, then the experience was good. In Bangkok we were offered a hotel, it was fine, but would have been nice to know in advance😉

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

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.

Always liked Thai Airways but in the past they have been very expensive, not being a millionaire just yet, I will use cheaper airlines. Bangkok to London £370 11 hours 45 mins. Old plane but ok. Lovely ladies on board, very polite. Food was ok. Will always use them if the price is right.

Could have been better. I prefer Thai airlines only but it hasnt been reliable.

Service on board was excellent. Flight attendant was very helpful. I wish the website is more functional. I can't even choose seats online and had to call the customer service. During check-in at the counter in CGK, I saw a printed page about paying for the bulkhead and exit row seats, so I asked the staff at the check-in counter. I was told that the flight is full and there isn't any seats available for paid upgrade. When I boarded the plane, I saw so many bulkhead and exit row seats empty and asked the flight attendant. He allowed me to purchase the upgrades on board. It would have been nice if I could purchase the upgrades ahead of time, eg. During online check-in or bag drop at the airport. The economy seats in the A350-900 are arranged in 3-3-3 configuration. Seat width is a bit tight for me.

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

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

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.

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.

We were delayed, but there was never any update given. Everyone was standing at the gate as boarding was supposed to commence at 13:10 for a 13:55 flight. We didn't actually start getting on the shuttles to the plane, until after 14:00. No updates, no information given at all.

Me and my Partner were in seats 6A and 6B. (Which we paid a premium for). Unfortunately the person is seat 6C was large and because of his size my Partner was squashed to the point of discomfort and unable to sit properly. We requested to be moved to some empty seats and two hours into the flight the crew moved us. Perhaps it’s time airlines began checking passenger sizes to ensure they don’t encroach into fellow passengers seating space!

Connection flights are smooth, both flight takeoff arrive on time, that will be the best u can expect. Food no order, service no complain, entertainment not seen, cleanliness can be improve.

U could offer everyone a drink ,juice or water.. coffe or tea ...ur air craft isn't a flea market ,where someone has to buy a tea or water!!
