I felt that the whole experience went very smoothly. The aircraft was extremely clean and tidy on boarding. The cabin crew were beautifully turned out very, very efficient and were a credit to Singapore Airlines who are now my favourite carrier.

No frills airline with minimal leg room and no entertainment

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.

Crews were very caring and polite. Washroom was surprisingly clean. Overall experience was good , only food choices was very limited. Thanks

The seats were more narrow than at other lines. Food was mediocre (economy class)

They made 22 hours aboard aircraft very enjoyable. I was very impressed with the attention to detail and level of service. Singapore airline will be my preferred choice going forward.

Once again the meal served was delicious - we got chicken rice

Crews are not allowed to perform any service whenever the captain deems there’s a chance of turbulence. Even if it is perfectly smooth air.

Leg room and flight sound insulation is very bad. They broke 3 of my bags with bad handling

I was very impressed with this airline. The flight was comfortable the plane was clean and the attendants were very nice. The zipper on my suitcase broke after I checked it. The airline wrapped it in plastic wrap, so it wouldn’t continue to fall apart. Every item I had in the suitcase was there when I got to Los Angeles. That is above and beyond!

Cathay has always been great. Even allowed some leniency on my baggage weight. I believe they are also on the more leg room side of airlines.

The staff from beginning to end we're friendly and helpful. The food and beverages were quite good (but see the comment below). I also liked their entertainment options, as we'll as their frequent attention to the airplane restrooms. Here are the reasons this is not a 5-star review: - You have to pay for WiFi on the plane unless you have some level of seat upgrade. - CP sent me a warning that the name I entered to book didn't match my passport. True, but the form for entering my name didn't allow for anything but a middle initial. This lead to a lot of chats, phone calls and stress before finding out at the ticket counter that it didn't matter. CP has modified their notice to now tell you this key bit of info. - After consuming a chicken dinner they offered (Kathmandu to Hong Kong), I developed symptoms entirely consistent with salmonella, beginning about 6 hours later. There were some odd things about the serving of this meal, too. Our row was the last one served, and we were given a tray without the entree on it. About 10 minutes later the stewardess came by and said they only had one chicken meal left. My seat mate and I decided he would have the lamb and I would take the chicken. I think I lost. I suspect that this entree was left over from an earlier flight and they were scrambling to get the last row fed. My seat mate and I were the last two to receive our entrees. I am not accusing CP of giving me a contaminated meal - just that the onset and progress of symptoms closely match those of salmonella poisoning. I opted out of the first meal on the next flight 13 hours later, but was fine after that.

Flight was kept super cold. I was shivering and had to layer up.

Boarding on any airline is a hot mess. Load your pivilaged passengers, then back to front. Back to front.

The flight experience was good for a long flight over the pole, but it got my wife to the Far East in time.

I love the comfortable business class seats. The service was excellent. Staff was friendly.

The lead business class attendant was excellent. Made a point of greeting you and knowing your name by the time you leave.

Better. I took an aisle seat this time. Although the overheard compartment above the seat ahead of me kept opening up during flight.

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

Uncomfortable seat/ bed. Opted for a front window seat without TV not working ). A bit smelly blanket and environment inside.

It’s sad how legacy airlines feel like budget airlines now. Cramped space Non reclining seats No inflight entertainment (need to connect via your own device) Saving grace is the crew. Truly nice and sincere service.

It was great! The flight was on time and had a smoother flight

Crew excellent calling me by name ! Only downside was no inflight WiFi

Delayed, from morning flight, they moved to evening. And said, their earlier flight is already full but we can upgrade the seat

Well it's strange everytime going the flight is late coming back the service is superior

Flight was cancelled and rescheduled to 205 in the morning at the peril of passengers. No hotels provided by the airline. Passengers left stranded at airport. Not acceptable. I was able to get a hotel at my own cost outside of the airport. No reimbursement. Won’t be my choice in for future travels.

Poor check in attitude , terrible food , movies selection poor, food came out cold , service terrible , entertainment system also broke so we had to use a iPad , worst biz class I have ever been on

Upgrade their seats. They’ve got 20-year-old business class seats in their 777s. The food choices. On the way to Manila and the way back I thought we’re lousy compared to other carriers. The staff was fantastic and very happy.

I was thrilled with this flight and look forward to flying again with Philippine Airlines in the near future…thank you

Need to upgrade the lavatory it was very filthy and disgusting. Very poor hygiene.

The crews were very professional and courteous. Pleasant flight and thank you!

They wouldn't let me on the plane. The 3rd party apparently didn't pay for the tickets properly?

Food was good but only 1 meal and 1 pie, instead of 2 meals. Both legs were late.

Jia yung was the flight attendant that made this a miserable flight.

Ok, but legspace on MH0127 from Kul to Per was too small. It was not possible to tilt my seat which I don't understand because the seat in front of my could do it. So I didn't rest on the flight. Also, the crew was probably understaffed because it took very long time to take trash after the meal. Everything very different from the flight with Malaysian Airlines from London to KL.

chaos boarding. Crew in business class seemed short staffed and lacking in attention to details initially, but did improve during flight.

Delayed, not enough information. Had to ask for refreshments, crew could have been more proactive

No recognition for one World Emerald member. I got row 1 in business class and it was pathetic. No leg space, cramped space, less recline

Cabin crew as always are leaps and bounds the crowning glory of MH. Friendliness and natural warmth are such incredible traits. Food was very good on this flight also; and flexibility in meal time to accomodate rest was a plus point. Early arrival and landing as the first morning inbound at T4 LHR meant I was off the plane and in the queue for an Uber in less than 15 minutes!

The flight is awful, food isn’t very tasty or good, entertainment sucks
