We were not given option for meals since they ran out of the other option but good thing the remaining options tasted great.

10.0 ExcellentBeverly, Apr 2025MNL - SIN
Read more Singapore Airlines reviews

We were not given option for meals since they ran out of the other option but good thing the remaining options tasted great.

Both the staff at check-in counter and on board were pleasant and helpful. My chicken and mashed potato was good, sauce was tasty, but the zucchini, carrot n other accompanying vegetables were over-cooked a little. (I understand the meal has to be prepared earlier). Yet I would fly on Singapore Airlines again and recommend it to family and friends.

Horrendous. We upgraded and they took the money but cancelled one of our tickets. The recline action didn’t work on the seats for the flight from Singapore to London, pre booked meals but they seemed to have disappeared as well.. Phone customer service was horrendous. Took 5 phone calls and no fix. Craig at the airport was the only one who seemed to be able to get the ticket back.

Construction at PDX resulting in very lung walk from the rental car to the gate. SFO, extremely long walk between terminals to get to connecting Singapore airlines flight. My smart watch recorded a total of 3 miles.

Loved the airline with the exception of their carry on limitations. They enforce a strict 7 kilo limit for carry on baggage which is ridiculous. We traveled from SFO to SIN with carry on with no difficulty yet when we checked in Delhi they forced us to check the carry on bags. The weight of our carry on bags were 11 and 12 kilos and while they exceeded the limitations set by Singapore Airlines they were well under weight limitations set by may other carriers. Interestingly my wife and I were each allowed two 22 KG bags to check in addition to the 7 kg carry on for a total weight of 102 KG's. Our total weight with the one bag we planned to check and our two carry ons was 46 kgs.

So happy I flew with Singapore Airlines. The customer service is top notch. I am terrified of flying and the staff made me feel so at ease. Will only fly Singapore internationally moving forward.

Food could have been better. Too many passengers getting up and down all the time.

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

It was very good experience on board to Sydney with SQ.

Everything was great keep up the good work 😁, can't ask for more.

Food no so good. Extra charge to much for front seats cost me £163 then other people sat near me for nothing 🤬

Ove the A380 planes. Comfortable seats. Served great Indian food and Masala Chai!

Except for the uncleaned tray, and the delay in serving food for our section (which may have been due to the location of our row) everything else was good. The crew were very professional and responded to our requests promptly throughout the flight. We as a family were not disappointed by Emirates.

The plane seemed pretty old and the food was not good

Thay crew was so nice.Air hostess il ham was so nice.my mom was little scray with airplan turbulence she help us alot.

Comfort and customer service from most if the crew was great. The crew reassigning passengers should consider the presence of infants when reassigning seats. Unfortunately a couple of oversized passengers were relocated next to us, making this segment a bit uncomfortable, as there was not only extra leg space required. I ended up swapping seats with my husband so our baby wouldn't be impacted. My husband travelled quite uncomfortable as the reassigned neighbour shoulder and arm ended up on my husband's seat

Loved that I had an exit row seat, and there was no one else in the row! And again, I don' use on-line entertainment at all (I read or sleep) but I very much appreciate that I didn't hear anyone else's entertainment!

Loved everything! This flight had premium economy and I didn't see an option to upgraded to premium economy OR buy premium economy tickets. How come?

The ground staff on Islamabad is horrible. The on board services are excellent.

They were very pleasant and helpful. My husband and I were sitted apart. We asked if we could be seated together were told flight ws fuly booked but would try. After a while they were able to make it work we got seats together. Their food is good and attendents are very friendly/helpful.

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

So so, crew was overly professional and lacks human touch. Equipment is very old, especially the HKG-PVG CX366 flight. That plane along with its decor must have twenty years of history, or at least I had that impression.

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

Crew was great. But a bit understaffed. The business class seat, etc were dated. But comfortable. Some legs had entertainment system from a decade ago. Selections were rather poor. Food was mediocre at best. Actually poor for business class standards. I liked the lounge in Hong Kong. Showers were great. Food was nice.

Overall, it was ok. However, the food was very sub-par.

It was okay overall but the food was very, very bad.

Fast boarding flight on time boarded plane back to front instead of stupid zone groups like US airlines do...

Baggage delayed for 2 days and still chasing for reimbursement of basis items. Very horrible customer care service.

Horrible. No good food. Baggage missed to onboard and came after a day. No support to compensate the delay. Customer care cannot see the status of the complaint. No reply of the email.

Excellent service provided the flight crew. Food and drinks were very good.

China Southern was not the problem. I booked my flight through Kayak and also received a booking reference and alert details regarding departure time and gate numbers… however Kayak NEVER actually booked my flight! We were stranded at the airport without a flight for a long awaited holiday!

The connection between LA and Atlanta was too much stress

Terrible boarding experience,,food is very poor that I I . Never going book this airline again.

The crew were kind, patient and responsive. The service was excellent, even though we travelled the cheapest economy class. We arrived at our destination 40 min early, which for a 15+ hour flight is a great bonus. The boarding seemed a bit "loose", but got us boarded on time, and the plane was off exactly @ 0:30 hrs.

The airport didn‘t give me the ticket. I called customer service to ask for a refund but they kept giving me a perfunctory response and refused to refund me.

The flight was delayed hours and most flights from CS are always delayed. Plane was efficient and got us home but not the best food and no entertainment system at all.

Not good - chair back could not move back for premium economy. Not worth the price

The back of the chair - premium economy could not move back - not worth the price

It was okay. Boarding the staff made you feel rushed like we were late or something

It was great. The staff were so nice and helpful the food was great and they always made sure I was okay. As a foreigner I was worried about the language barrier but it was absolutely no issues. I highly recommend

Flight was on time. My group paid for seat’s so that us four can be seated next to each other. We all got separated. We all got middle seats, which made it more difficult to be able to get up and stretch or use the restroom. We tried talking to the employees at China Eastern and they were of no help. We will not be taking this flight or recommend this route to others in the future. Also I will be contacting customer service on how I can get our money back for paying for assigned seats.

China eastern was fantastic. I had read so many bad reviews that had made me nervous. However, I found that the flight attendant’s, and customer service check in etc. etc. was excellent. I had no problems. I would fly with them again!

Excellent! I had read some negative reviews but I found out that it was not all was not true! The staff was courteous and helpful. The flight take off and landing was nice & easy. The food was good! I asked for a second and I got it easily and without an attitude! All was wonderful!

Excellent experience however older aeroplanes used by China Eastern Airlines.

The crew were excellent, service amazing, blankets and pillow good, cabin temperature perfect, the flight on time, food was unusual selection however plentiful, price for tickets unbeatable through Kayak. Older aeroplanes used by China Eastern was the only down side.

Delay in off-boarding due to customs at SFO... pilot announcement should have come earlier so passengers don't clog aisles.

Better good than most, if not all European airlines. If you’re stuck in an economy seat anyways, China Eastern is a good choice because of shorter flight time, being able to overfly Russia

The temperature of the plane cabin is too hot. Sweat and uncomfortable. Also my food tray was broken down drinks fall off

Reasonable. What they offer during the flight is not great, but the crew is polite and try to compensate it.

Price is the main attraction. Staff is OK but difficult to communicate with them due to general lack of English. Food is truly abysmal, the main courses (4) were barely edible. The choices for breakfast served at 5:30 am prior to landing at Gatwick airport were Spaghetti Bolognese or seafood fried rice. Choices offered for all 4 mains were either something rice or noodles. Shanghai airport layover is much too long in a very poorly serviced airport. We were unable to use WiFi; private lounges required cash only payment with no ATM or cash exchange open.
