The seating is spaced out nicely, The crew could have offer more drinks.

Very uncomfortable aircraft. No free entertainment or drinks. Food okay. Won't fly with them again.

Excellent comfort and entertainment. Service poor..Food average with little choice.

Comfort good. Service as usual poor. Cabin temperature as usual too cold, about 15 degrees

The plane seemed pretty old and the food was not good

The plane was clean and well maintained the crew members were professionals and friendly and the food was good

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

Boarding, seats, entertainment and service were all great. The food was great except for the fact that there were too many sweet items.

The service on board was excellent, the flight wasn’t overbooked and we departed and arrived on time.

The usual excellent experience with Singapore Airlines. The airplane was on time and actually early to Haneda Airport. The onboarding experience was pleasant with no delays, perhaps owing to the fact that the flight was not full. Nevertheless, the air crew were their usual outstanding standards in serving the passengers.

Good service and food. For buying items on flight should be preordered as they don’t keep much stock on board.

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

The seat in economy class and legroom in Singapore airline are narrower than Korean airlines! I don’t have that comforting feeling flying with Singapore air as in the past!

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.

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.

Check in was easy through self-check-in kiosks just like domestic flights. Staff onboard were fantastic. Some "book the cook" good options weren't great, others really good. Entertainment options a bit limited to what I've experienced on Qantas. Overall a good flight though, especially for the price.

The staff on Singapore Airlines was incredible. I would like to commend LS Reuben from my SQ37 flight on November 19th, 2024, from LAX to Singapore, for his outstanding service and care. During the flight, one of my earbuds—brand new and valued at nearly $300—fell out and became lodged in the box controlling the in-flight entertainment system. I was understandably upset, but Reuben went above and beyond to assist me in this tough situation. Reuben demonstrated exceptional determination and empathy. Instead of suggesting we wait for an engineer, he immediately took action, spending almost 30 minutes searching for the earbud. He even got down on the floor to ensure it was recovered. His genuine concern and persistence made all the difference and turned a frustrating situation into one where I felt truly valued as a passenger. Reuben is a shining example of the remarkable service that sets Singapore Airlines apart. His dedication and willingness to go the extra mile left a lasting impression, and I want to sincerely thank him for his kindness and professionalism.

The 10hr flight was a comfortable as it could be in row 57. The food was just very bad….bland and soggy!

The business class upgrade meant a good sleep on the way home after a long week away. Excellent service, great food, and comfortable seat/bed for the journey.

I love the “boarding from the back” idea - it’s so much better than the “Zones” idea that many others use. Also, the inflight wifi was a first for me! Very nice to have on a 13-hour flight!

Again, Air New Zealand was great. They kept bathrooms clean, food was actually very good, New Zealand wines a big hit

The issue was with getting our boarding pases. There were issues with our arrangements that were made through Kayak. I am sorry to say that we will not use you again because of this. The flight itself was good and the flight attendants excellent.

Arriving at Coolangatta, rows 20 forward, took the airbridge across to the terminal. It was suggested to those from rows 21 back, that we take the rear stairs and to be careful crossing the tarmac. That was all well and good. However, when we got across to the terminal we then had to climb three large flights of stairs to meet up with those coming across the airbridge. No elevator! There were people carrying babies and elderly carrying hand luggage that needed assistance from others.. There was no option to turn back.

It was good for a short domestic flight. As no food ar entertainment provided, there should be a n/a rating available for those.

USB charging ports did not work on any of Air New Zealand flights

Economy was much nicer on the Air New Zealand planes.

At Coolangatta International it is difficult to hear voice boarding announcements when away from screen announcements.

Was bumped to a later flight because of inefficiency on part of the airline.

Inflight entertainment, poor that there are no headrest screens on aircraft used for an international flight.

Delayed QF59 flight once again, Qantas doesn't fail in maintaining there delayed departures and arrivals. USB points do not work nor do the power point sockets on the plane, Qantas staff admitted that on the flight. Don't expect to your charge devices. Saving grace, was the ice cream. Bottom line, if you expect to fly to HND and make it on time avoid Qantas and if you're interested in ice cream - visit 7/11.

Loved the staff. The economy seats could have been bigger.

Friendly staff, surprisingly good premium economy seats allowing good sleep/ snooze opportunity and very good menu.

The old Plane had not been cleaned properly in a long time.

I got upgraded from economy to business, and the experience was outstanding

Boarding was over 3 hrs late and we didn’t land until almost 1:30am

Delayed and missed connection, was not re-booked like other travelers so ended up being stuck for several hours due to no one handling my booking.

American Airlines was their usual junk service — but at least it got us down to LA. I was more irritated that while they codeshare with Alaska Airlines in Seattle, they could not out our flight on one of these, opting for one of the small SkyWest operated American Eagle flights — and causing a 14 hour layover. Which I accepted due to a $2000 difference in airfare — that said it was irritating for a flight that usually would have cost around $100 extra, if that.

Wow very impressed by the quality and attentiveness of service of China Southern. Lived the blankets! Will definitely fly with them again. Despite language barriers, a few attendants know enough English to understand our rudimentary Mandarin and respond to basic questions. Although they don’t explain the beverage and meal service on the website or ticketing documents, they offered regular beverage cart and snacks during the beginning hours and end hours of the long, transoceanic flight. A full meal at the beginning and end of the flight as well, and a midflight small sandwich (dinner roll sized) but we weren’t hungry and didn’t try that one. The expectation is that every sleeps during the middle of the flight. We were on a “redeye” departure from LAX with a morning arrival in China, so I don’t know if this service pattern is the same for other flights. The domestic flight we took from Guangzhou to Harbin offered conventional refreshments and meals like a US flight service. Note that they didn’t offer diet sodas. If you like to stay hydrated, I recommend bringing plenty of your own. It is served in small cups like any other drink. You can ask for a bottle but they’re tiny - about 6 ounces.

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
