Had to take a shuttle bus from boarding gate to the plane and climb steps to the plane. I already knew 737-Max 8 was a small plane with only two toilets at the back for the entire economy cabin. If you sit among the last 5-6 rows closer to the toilet you will have passengers standing at the single aisle queuing to go toilet next to you as there could be more than 5-6 of them waiting at each time especially after meals. That said the crew was prompt to ensure the toilets were checked and in good order at intervals and they remained clean for use. The plane ride took close to 6 hours rather than 6.5h and despite taking off late some 25 minutes we arrived ahead of the scheduled time due to a shorter flight duration. In-Flight was challenging due to narrow aisle and quite slow. Food for breakfast was served rather late and a bit of rice grains were not fully cooked. good variety of juices and fruits + yogurt served. Flight was smooth.

I paid extra for assigned seating. When I checked in my seat had been changed to middle seat middle aisle. There was a reason I paid for an aisle seat. I did not sleep the entire 14 hour flight, preceded by a five hour flight from Kathmandu to Singapore. When I arrived in San Francisco, I had gone 40 hours without sleep. My immune system was compromised and I caught RSV flu. These days I hate flying!

Flight attendants were awesome! Very helpful and patients. Some food were good but maybe not serving fish that kinda make the whole aircraft smell fishy. The “fried pork” was tasty but too much skin so it doesnt taste that great.

They ran out of the second choice of food was stuck with fish

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 was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

A 16 hour flight from Singapore to Los Angeles had only 2 meals. Please make it 3 meals.

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

When boarding, after business class should be premium economy, but economy class already lined-up at the gate blocking premium economy to board. Singapore airline crew should done a better job to organize this chaos :( Thank you.

Cleanliness Help for boarding and sitting Food should have been better

Seating business class, the entertainment screen was old and clunky, and No WiFi, food was poor

When landing in Hyderabad, the pilot made a hard landing. Everyone in the plane were shocked. The captain landed the plane hard and felt as if we were going to be thrown out from our seats. It was surprising the captain didn't apologize or make an announcement about. Again a surprise no crew acknowledge this. This was an odd experience!

Terrible. Air India canceled my flight out of Kathmandu because of airport constructions but did not tell me. They should not be selling night flights out of Kathmandu right now that they know they will not honor. The staff was terrible and not helpful with my rebooking or compensating me.

Flight leg to and from IAD/Delhi was good. The leg to and from Delhi/KTM was terrible.

Their security process is excessive. We were checked when we got off our incoming plane, at the gate and up the stairs when boarding the plane. Come on.

Interment is zero tv wasn’t work phone charger plug doesn’t work moves doesn’t work

My inflight entertainment system didn’t work for the entire round trip ,16 hour flight without any inflight entertainment is tough

Flight crew were welcoming and attentive. The flight was on time and arrived a little early. Overall a very good flight!

Mumbai to Delhi aircraft was unfit for flying. Seats in front of me were broken and cracked , tray table falling apart. Seats loose shaking. During Take off and landing there were loud banging noises and plane almost drifting off the runway. Fight delayed by 2 hours. We're told by crew that it was due to technical issues, no wonder given the aircraft conditions it was flying in. Very old airplane

No organized boarding procedure and TV screens in most of the seats didnt work. For a 14 and half hour flight, without any entertainment made it much worse. Recliners in the seats were not working properly.
