Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

10.0 ExcellentYM, Apr 2024MEL - SIN

Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

Excellent meal served with real utensils, cardboard served hot meals instead of plastic utensils and plastic covers. Quick service, friendly and accommodating stewards.

All in all the flight was good. Love the fact that for airline food it was piping hot

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 :(

Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold

Wonderful service, planes and interior in great condition, very pleasant experience

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

The premium economy seats were not that great. It could have been more premium than economy seats.

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