Seating wasn’t good at all with not much leg space in between. Fortunately it was a relatively short flight. Otherwise we would have struggled a lot. On board meal was pretty ordinary. It is sad to see the overall quality of this once superb airline has dropped so low.

Seating wasn’t good at all with not much leg space in between. Fortunately it was a relatively short flight. Otherwise we would have struggled a lot. On board meal was pretty ordinary. It is sad to see the overall quality of this once superb airline has dropped so low.

Very good customer services before, & during flight. I will choose it again in the future.

Pros: "The crew was great although I needed to ask them for my meal cause they passed by me. They thought I had my meal already which I didn’t. I don’t think they did it on purpose so it was just misunderstanding. My flight was on SQ 38 from Singapore to LAX on October 30 2019 Other than that. All is amazing. I will still highly recommend Singapore Airlines to other people."
Cons: "I think I have nothing in mind about improvements because I can see they have been training very well. I would like to say keep up the good work"
Pros: "The crew was amazing. It was my first time flying so I was a little nervous but they made me feel safe and welcomed. The friendly crew was honestly what made the whole experience great."
Cons: "Having a reservation on Alaska for the first leg of the trip would have been nice. They didn't expect us, we had no confirmation number that Alaska recognized so we were denied boarding. How much else could have gone wrong?"
Cons: "Luggages did not arrive with the flight as it should be. It got lost in Sydney from Queenstown on flight SQ 6683 operated by Virgin Australia (VA 162)."
Cons: "Flight was canceled. They moved passengers to the Lufthansa but didn’t tell us even though we checked with the counter every 20 min. Apparently a text went out that we didn’t get"
Cons: "Singapore airlines use their antique aged flights for services to chc.unconfortable and a poor in-flight entertainment system"
Pros: "smooth boarding process excellent enterntainment offered food is also quite good"
Cons: "seats seem to get smaller, less comfortable then I am used to with Singapore Airlines"
Pros: "Great service and attentiveness with great food and entertainment, including a nice big comfortable seat!"
Pros: "Non-disruptive 15-hour red-eye flight from Hong Kong to New York was appreciated. Smooth and comfortable flight, no complaints here."
Cons: "In-Flight Wi-Fi was not available once reaching the continental United States."
Cons: "The crew should be friendlier while they deliver their service."
Pros: "Seats are ok, not super comfortable. Legroom are kinda limited but the monitor screens are great and user friendly."
Pros: "Nice plane. Crew was great. Seat not bad for economy."
Cons: "Only complaint was the 5 or 6 hour delay because of the weather."
Pros: "Crew is very good and efficient, generally very friendly and helpful. Seats are fairly spacious and comfortable. The flight was only slightly delayed. Food and drinks are quite readily available. Meal quality is nothing amazing, but it's definitely not bad."
Pros: "My flight was delayed, at check-in I was offered an earlier flight that was departing in 40 minutes. Because premium economy was full I was upgraded to business class"
Cons: "not getting any AA miles for economy / economy plus tickets on Cathay. Will make me consider flying alternatives like Thai next time"
Pros: "Everything"
Cons: "Bathroom is clean, but could be better if more attention is being given."
Pros: "Checkin experience was great. Boarding was great. The crew was great"
Cons: "The movies were old. Not many new releases to choose from"
Pros: "The seats are old .. the plane is old .. the flight was delayed 2 hours, food even in first class lounge is not apetising the menu has been cut significantly.. lettuce and tomato say that they are not sourced from China .. must be from India as the quality sucks"
Cons: "On time is an expectation that if you travel from HK to BKK on CX that it is always delayed .. common knowledge for people in Thailand.. this is bad"
Pros: "Everything was top notch,crew were super professionals,food was delicious,look forward to flying with them again!!was one hour early on first leg of journey"
Cons: "Softer seats"

PAL Airlines is always delayed most of the time. Please try to avoid it.

Pros: "the seat are comfortable. Flight stewards are responding to anything I need but on the downside, lavatories are clogged most of the time ( maybe because too many are using it.) Another issue is the travelers card, the letters are printed too small that seniors like me can't read it inspite of the fact that I'm wearing my eyeglasses."
Pros: "PAL crew, as expected, was good. we arrived sfo ahead of schedule.."
Cons: "i think desserts can be improved"
Pros: "yes the crew are good and accomodating"
Cons: "hoping the seats can adjust a little bit more to recline"
Cons: "for a long flight seat could have been a bit bigger."
Pros: "Yes, they were nice and approachable at all time. The seat was fine, I slept most of the time"
Cons: "Never on time. Almst missed connection. Planned on 4 hours. Downn to the wire. Nevermore."
Pros: "None"
Cons: "I am Filipino and would really love to support this airline, but I can’t help it; the airline really needs to get it together. This is the second and the last time I’ll be flying with this airline internationally."
Pros: "Friendly crew"
Cons: "Not sure what that sandwich was supposed to be... but it was not good.. some kind of pseudo-Spam."
Pros: "food, crew, comfort were Okay. In-flight entertainment could use more improvement -- probably more asian content or travel-related shows."
Cons: "the 6-7 hour delay was handled very poorly -- lack of information; no airline manager so the answer all passengers received were "We are sorry but we aren't in a position to answer that." When asked about possible compensation, the ground crew answered "We'd have to wait until we reach Manila (which was at least 17 hours away)" -- This just made passengers more irritated and the ground crew were forced to call airport security. boarding very unorganized on our return flight."

On time and smooth flight from San Juan direct to Sint Maarten.

Just to be expected on a budget airline. Since all the flights were either late on the evening it would help to offer some food for purchase Since you tourists cannot buy decent food withoit local vaccination record in hong Kong this would really to help Using phone to submit electronic data is great but for the elderly this is a hassle

Flight cancelled without notidication, had to book an emergency replacement flight at the counter

Cons: "We should have been allowed to sit near our family (wives). There was empty row but they wanted to charge us to move up. Ridiculous!!"
Pros: "Absolutely nothing"
Cons: "The flight took forever to land. Pilot said prepare for descent and we stayed in the air for another forty minutes. The air smelled awful. One of the worst flights I’ve ever taken."
Pros: "I was able to purchase extended seat room for a reasonable price."
Cons: "No free drinks or entertainment or anything to help pass the flight time."
Cons: "Staff at check-in counter were not helpful. They were there and they weren't. We were there at the front while two of the counters were ready but didn't call us up. They were chatting with each other instead. We I asked them are they ready to work, she ask me where was I heading. What is the difference?"
Pros: "Price was good and HK to Tokyo times were good"
Cons: "No entertainment on 5 hour flight"
Pros: "Nothing in particular."
Cons: "They don't tell you that 1) you aend up paying more than other airlines charge by the time you add various 'extras'; and 2) you have to go through immigration because they are in another terminal. This means two hours of work, plus I missed my flight because I didn't have 3 hrs. They said my fault."
Pros: "Good price to go HK to Tokyo"
Cons: "Flight attendant woke up a baby to tell passenger something and then baby cried for next hour No water unless you pay for it"

Scoot refused to change my flight even though I had booked a flexible ticket. MyTrip wanted to charge me an extra $271 for a ticket that was only listed as $217. I complained about this to scoot and they didn't give a shite. So never again will you be getting money from me Scoot. You can Scoot off.

It would have been nice if I could have actually travelled to Perth. I injured my back and was unable to fly. Scoot refused to change my ticket saying it was not flexible. However I purchased the ticket through MyTrip and it was flexible. MyTrip wanted to charge me an extra $271 to change to a ticket that was only listed as $217. Never again will I fly Scoot or book through MyTrip

It was a cheaper flight and it arrived early. I thought the crew were pretty noisy for an overnight flight, and my friend was not able to sleep because of the noise. Also I think it’s absurd they don’t provide complementary water. Why does everything have to be a surcharge? Airplanes are dehydrating and it would be beneficial to help passengers stay healthy.

Pros: "The crew were super patient (a must when dealing with the quality of passengers from Trichy who were lacking in manners and etiquette)."
Cons: "Boarding was chaotic. The majority of passengers seem to not be used to the normal manners and etiquette of queuing and it was chaotic with pushing. Some discipline and order needs to be enforced by ground crew (and this will no doubt make the cabin crews' lives easier)."
Pros: "Extremely rude."
Cons: "I got sick on the flight from some food poisoning and the crew acted put out when I asked for some water."
Pros: "Loved the tinted windows on the Dreamliner! And the rainbow lights at the end of the flight. Scoot personal were excellant!"
Cons: "Things to know: Need to download an app before getting on the flight to get ScootTV. Plane was a little loud."
Pros: "Organised well. Clean plane. Excellnt comms from pilot and staff presented well."
Cons: "Could not recline chair"
Pros: "Overall it was a good flight."
Cons: "No offer to book my seat assignment during the booking process. A kiosk check-in would be a nice addition."
Pros: "Crew on Singapore airlines were very helpful, friendly and accommodating."
Cons: "They had 0 entertainment on an 8 hour flight. Tv turned off. One small meal after 20 minutes of flying. Would not fly with scoot again."
