Three meals on a single flight is disgusting. Even if I reject them all, sleeping is impossible and all that food (especially wasted food) is just antithetical to a pleasant flight experience. People were chucking multiple abandoned trays on the floor in front of my seat.

Three meals on a single flight is disgusting. Even if I reject them all, sleeping is impossible and all that food (especially wasted food) is just antithetical to a pleasant flight experience. People were chucking multiple abandoned trays on the floor in front of my seat.

Similar to Hyd->Dubai this too was worst airlines. Bad seats, bad seating arrangement which created lot of confusion since family member were not given seat together. However most of them changed the seat and got with the family. Cheap tactics by Emirates.

The best ever, friendly and attentive cabin crew, amazing captains who utilised their expertise for less turbulence, just overall amazing

Overall I was quite pleased with the experience; the cleanliness; the polite and attentiveness of the cabin crew; and the delicious food options.

I would never have been able to make the transfer in time without asking for a wheelchair

Good food, real silverware, polite staff, smooth landing, charging plugs, good entertainment options.

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!

The entire crew was amazing. They went out of their way to make us enjoy a great travel experience.

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?

We had to deboard using stairs. Why didnt you have the aero-bridge?

Airline should consider adding a small meal at the last leg of the flight, right now there is 7 hours of no meal break.

The staff on the plane were attentive and friendly. The frustration with the cabin crew was that we were served second to special diet people. And, we were in economy section. The boarding staff was mediocre. Got scolded for requesting to sit with spouse on 14 hours long flight home. Was told they cannot break up families for us. Didn’t understand how we were denied sitting together as we are husband and wife. After many words of exchange, we were accommodated. Cleaning crew did a horrible job! Bathrooms were unsanitary or dirty from beginning of flight! Didn’t expect sparkling as its economy, but did except decent.

The food wasn’t good at all. I skipped meals .

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.

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.

Flight from SFO did not include entertainment as it was not working the entire duration of the flight. Was informed that there would be a $350 voucher for the inconvenience. Uncertain how the voucher will be provided.

I very much liked and appreciated the service on board. The seating arrangement in Business feels uncomfortable. It's not made for tall people, in any case.

The flight overall was good. The attendants did a good job except that 1 female had too much fragrance on. The other things that made the flight unpleasant were out of the airlines control.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

I would love the entertainment center to be updated with more content. The flight to Doha had more options than the one to Miami

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

Not sure how we end up with American Airlines instead of Qatar Airways. From Philadelphia to Qatar they boarded us then they asked us to unload. After 30 minutes later they board us again. The inside the plane it was burning hot and we were sweating like crazy. Crew members are absolute rude. The way they served the passengers were horrible. One of the crew members hit my knee with food cart and kept going. I was holding an ice pack for almost 2 hours. I am still with the pain.

I felt that when I was rerouted it should have been to business class.

The flight was smooth Thank God but the delays and changing gates for 3-4 times made me so tired of walking back and forth with heavy bags I thought I was going to pass out with heavy headaches but Thank God finally found the final gate and home safe. These delays happen anytime for important reasons so just be patient when you come across these situations.

Worse fight I ever take since I start flying , still have even made home , and crew abandon us half way home . No water no food and no even anyone to answer our questions

All the crew members were too slow and rude. Most of the times the registers were empty, while hundreds of customers were waiting in line, and it was impossible to get a supervisor. Despite being in line on time, I missed my freight, plus a some customers who were ahead and behind me.
