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

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

Perfect experience from boarding through to leaving the flight, comfortable and personalised service from all staff, highly recommended

They were able to assist my elderly father and myself after not being able to check in to scoot. The counter service was phenomenal. They did what they could to get us on the next plane so we could catch our Connecting flight. Scoot closed early on us so we ended up missing our flight.

They are great with every aspect of customer service. Helped my elderly father and aided him with using the restroom.

Even though it was a very full flight, the service was still excellent, the plane did not feel too cramped and cabin crew made a sincere effort to help passengers find overhead space for stowing luggage.

Due to the delay of my first flight, my connecting flight with JetBlue was canceled by Singapore Airlines, but the JetBlue crew was very accommodating and rebooked a seat for me. The crew was very nice and had good attitude.

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.

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

The crew were fine. I didn’t enjoy the food at all. I found it unappetising and really had trouble eating it. The comfort level was fine and our return flight is with Cathay Pacific but honestly I probably wouldn’t fly Cathay Pacific again.

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 .

Average flight for which I paid too much for on a last minute purchase.

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.

Cons: "The flight delay could have been announced over the speakers"
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."

It was fine. Flight was on time and arrived at destination with 15 min to spare.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The food that was offered based on class level of your ticket was absolutely ridiculous and disgusting. They didn't even hot tea to serve, the food was horrible. On our departure flight I was seated in premium plus economy and considering the cost of the flight the food was literally some of the worst I've ever eaten. On the return flight I sat in economy with extra leg room and was given a thin little throw "blanket" and a flimsy little pillow. The air condition was on artic and the seating arrangement wasn't really worth the money. The seat didn't recline good enough and the foot rest was laughable. Total waste.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

The flight was delayed due to weather issue…WiFi did not work and even though I wanted to pay for WiFi I couldn’t buy it. Overall very disappointing even though I paid and reserved Business class

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

All flights were on time and boarding was issue free

The crews at check in counter are not professional, they are talking and playing around. Also no entertainment on the plane

2 failed landing attemps before going to Nagoya airport for refueling. After 3 hours of taxiing, we still needed 3 attemps before a succeeded landing (after the 5th attempt finally!). In total, 11 hours inside the plane instead of 4h30, and with only a crappy piece of bread to feed us. A shame.

Pros: "No IFE without warning. 16 hrs. of nothing. very uncomfortable seats. Flight admits HKA going under and can not pay bills, customers suffer."
Cons: "No IFE without warning. 16 hrs. of nothing. very uncomfortable seats. Flight admits HKA going under and can not pay bills, customers suffer."
Pros: "This airline is going out of business in the US. They have had great fares from LAX to Hong Kong and Bangkok. It seems the airline has been mismanaged or has had political restraints despite always being full. I was lucky to purchase the last roundtrip flight LAX HKG BKK before the online bookings were pulled for the LAX route. Hence, my flight to HKG and the return to LAX were empty flights, which is such a loss for an already dying airline. The crew were still polite and hardworking unlike US airlines."
Cons: "Now you cant fly LAX or SFO to Asia on this airline. Bezos or Gates should buy the airline."
Pros: "New aircraft"
Cons: "There was no entertainment at all for the entire 15 hours."
Pros: "Crew was great."
Cons: "Entertainment was not functioning whatsoever during the 15 hour flight, not enough food choices."
Cons: "To simply find how much weight I’m allowed in every section of the flight. Also I couldn’t check in online with ELAL maybe because the ticket was a Hong Kong Airlines ticket operated by ELAL"
Pros: "Nothing"
Cons: "It could have been business class like kayak sold me"
Pros: "Horrible."
Cons: "Everything was wrong and kayak knew they were selling me a scam ticket."
Pros: "A little bit better with the service but the opportunity to be great like the other airlines I experienced was missing. To be honest the plane was one of the newest model around but looking and observing at the seats and restrooms, etc, I was not impressed. I feel like it was so cheaply done and maintenance was so poor."
Cons: "Offering cheap fares does not mean poor service and being treated with rudeness and so so service. In every year that I travel, I try different airlines to see and experience. I say that this experience is the worst and will be forever be embedded/marked on my list. They should look into service more to make up for other shortcomings I observed. Really felt bad not for me but for the other people who also got mistreated with the crews rudeness and their mean attitude towards work and guest. I work in a service Industry and all I can say they are not even at par to our lowest standards in what we do at our work."

Captain smooth landing, Crew efficient and helpful. We saw Mt Fuji from the plane. Thanks.

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."
