Good flight. Fiod was ready a bit late hence a hurry to finish before landing. Excellent crew and service

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

Awesome as always. I wish though the cabin for premium was upgraded.... Same old sane old :(

It was a great flight Food was great Crew was spectacular

In general good, but the machine seems to be long in operation and some functions were restricted as e. g. Adjusting of seats.

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.

Every thing was fine. Some ild classical Hindi movies should be add

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

The singapore airline now compared before covid, I like the service before covid. SQ was the best of all airlines but now I am going to look for different airline if I am travelling in asia.

Flying with Singapore airlines is always excelllent - the crew are lovely and the food too is great. It’s my number 1 airline
