The flight arrived on time. 2×2 seating meant no one needed to sit in the middle. This was a connectibf flight from Singapore and required going to 3 counters in different levels to check a golf bag

toilets could be cleaned more frequently, everything else was pretty good.

a completely full flight - felt quite carmped in, despite being on the window seat. Meal served could better. Surely different from pre-covid trips I used to take to and from Bangkok.

Lounge a access was excellent as was the attentiveness and service from the crew as always. The food and drink supplied were of good quality. The entertainment system had a good selection and I liked the mapping system supplied. However the screen wild have been bigger and the operation a little smoother to navigate. The seats were barely comfortable, but adequate.

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.

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.

Very good flight from Boarding to landing -efficient and comfortable with decent entertainment options

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.

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.
