Pack a hoodie and wear pants. Don't purchase anything past initial security check- youll have to empty any drink- even a sealed cola can- before getting through a secondary screening at your gate.

Check your all or most of your luggage if you can. Take a small light carry for your must have items with you such as snacks, book and electronics on hand accessible during the flight.

Bring a sweater, a mask and wear socks. Although they provided a blanket, it’s very chilly on a long flight. I caught a nasty cold from the flight and wasn’t masked up. Other than that our flight was great and comfortable.

Wish the seat don’t have restrictions, can’t fully insert backpack all the way inside.

Best service airline. The cabin crew is attentive and friendly. Inflight entertainment system is good

I was in a middle seat where I felt a bit too cramped otherwise the trip was good

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.

Crew and service excellent. 2 hour delay for takeoff. SQ app showed flight on time.

Food from Surabaya was below average but from Singapore is much better

Excelent service and plenty of food and drinks during the flight. Flight crew very attentive to our needs. Leg room between rows are very disappointing.

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.
