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.

The staff was great. I also like the movie selection was great. Lastly, it I appreciated the fact that wine was a drink selection.

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!

It is not so much I had bad experience with Singapore Airlines, but with Kayak and particularly Underpricer. My wife and my seat arrangements were changed some times after we booked our tickets and reserved our seats I February 14, 2026. However, after our arrival we realized that we were separated and sitting in different isles. Our return tickets indicated the same. Our several calls to your Underpricer customer care were useless as they cared how much they could charge us rather than actually help us. At the end they referred us to Singapore Airlines. If that was the solution, why did I have to call your Underpricer customer care. I will definitely erase your app from my phone and I will never use Kayak for future traveling. After all, there are so many agencies that I can use other than your company.
