plus: service and personal assistance minus: online check-in did not work

The Premium economy class is not the same as some other airlines because there are no economy seats on these planes. Basically you’re getting an economy seat that’s a little wider. The seats are not that much more comfortable. The service and food experience is similar to economy class on other Asian airlines. There aren’t enough toilets for the entire plane therefore we are forced to share the business class toilets that are closed off with curtains.

My overall experience with Singapore Airlines is great. Will definitely fly Singapore airline again.

Excellent meal served with real utensils, cardboard served hot meals instead of plastic utensils and plastic covers. Quick service, friendly and accommodating stewards.

All in all the flight was good. Love the fact that for airline food it was piping hot

Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold

When boarding, after business class should be premium economy, but economy class already lined-up at the gate blocking premium economy to board. Singapore airline crew should done a better job to organize this chaos :( Thank you.

It seems paying premium economy does not make difference with economy. No priority boarding, not worthy paying extra$$$ for premium economy.

Wonderful service, planes and interior in great condition, very pleasant experience

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

Very comfortable Prem economy seats for a long haul flight. Had a problem with the tv that the crew fixed so was great!

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.

Very poor check-in experience, and flight meal service was very disappointing with no drinks service or hot meal.

Lounge in pukhet not good Very nice new aircraft Super crew as nearly always with Cathay

I felt thirsty and asked the flight attendent for water, but no one came for more than half an hour.

Everything went smooth. All flights were on time No changing gates, . No changing flights . It was like a completely different airlines tha n the last time I used Cathay Pacific . The last flight, 2 months ago, I had before this one was from Philippines also . I got changed in Manila and was told it only added 2 hours onto my flight . My 20 hour return trip ended up being 30 hours return with a 10.0 hour layover in New York with no seats anywhere . Everyone was sleeping or sitting on the floor . Unlike the hotel I was given in Manila to wait for this flight home . I never thought I would use Cathay Pacific again . But I did and this time you were great! I should have complained about the flight and layover from Hell a couple months ago. Consider that I am complaining about that august/23 flight now . Thank you got the great flying experience on my way home from philippines .

Everything was good food could be better but ok for economy on my 2nd flight the head ph jack are bad you have to hold pushed in to hear anything but other then that very nice service

Cathay much better than other options Imigration was a total mess on arrival in KL but not Cathay s fault

Would have liked working outlets on the flight. The first meal was very bleh, the second meal was a lot better so overall okay meals

I traveled to Singapore for 5 days, I didn’t receive my luggage until the 3rd day. When I received my luggage was broken which they fixed it supposedly. I never had such a poor experience with the any other airline. I honestly think it should be a compensation for all of my losses and suffering that I went through.

The plane had a technical problem it would delayed 10 hours but they just gave limited information and put all passengers into the Miracle lounge. Ther were not enough chairs and so on.

Ensure there is a choice of food for all customers and also enough food

An excellent airline; polite and courteous cabin crew, excellent meal and drink service. Highly recommended.

We boarded the plane at 1:20 pm It was hot. There was no air-conditioning It was stifling They kept us on the plane sitting there for 1 hour and 10 minutes

No space in between the seats as per them the average height of human is 5’3” and weight as 55, so seats are designed as per the same. Also, the aircraft was dirty and full of insects

when we arrived at Taipei no one help us to get boarding pass. we saw a few people there asked them for help but they just ignored us. There was a guy told us to call Starlux number to get help but we don’t know how to dial the number until there was a lady working there helped us to call Starlux customer then someone came down took us to another counter for boarding pass. Very confused and inconvenient. We might not choose Starlux again in the future.

There was no entertainment and food option limited But the service was first class on an economy flight

They didn't have a vegetarian food in spite of the ore order

Technical problems checking in. Had to wait a long time while they got things ready.

Vietnam airlines is just one step upper to the cheapest one (vietjet, if you wanted delays and cancel or feel like a criminal then vietjet is for you) for sure better customer cares and on time.

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.

Not clear why boarding passes could only be issued at the counter and not through the kiosk. I had already check-in on the web, so waiting to obtain a boarding pass 1.5 hours before the actual flight defeats the purpose of early web check-in.

no charging point. food offering is limited and very much on the budget line. Overall is not satisfying for such a price and duration of flight.

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.

Paid for seats near the window but given seats right at the back, near the toilets. This location was so noisy with the blasts from the aircraft engines blowing beside. Not a nice one 😞.

Flight was delayed 2 hours, which seems regular with this airline. Aircrew were avarage, friendly but robotic. At check in I asked for a spare seat. Got some stupid response about loading capacity (it was 85% full!) Then passengers behind jumped up and moved to vacant exit rows, they obviously didn't pay for. Waited over 20+ minutes to disembark, with ground staff trying to squash all passengers onto 1 bus. Causing even more delays. Unsafe and stupid! But this is a problem at Saigon airport. Overall a very average experience!

In experience we didn't even get water unless it was paid for. Even Bamboo Airlines provided free water. The flight was cold with no blanket being provided. The flight attendants were not responsive in keeping the passengers under control. I complained about fellow passengers playing loud music several times before one of the flight attendants to action. I will not recommend flying with Vietjet unless things improve.

I have few bad reviews about VietJet, but my experience was really good and it worth every penny..

Not even free water. NO legroom. Narrow seats. Not enough room to even hold a book at reading distance in front of you.

No food? No movies? No water?? On an international flight, really???

No water or snacks. Crew did not give us arrival cards. There was no need for more than 1 flight attendant as they did not do anything

I got to the airport and flight was cancelled without notice

Some chair in the flight should be maintained, but I think they may not have time to check every seats, since it is high demand in this period.

Our experience was the worst. Over 2 days flight was changed and delayed 4 times. Not impressed
