This is THE BEST airline. I can see why they consistently win awards!

It was fine. Nothing special but nothing went wrong so all good.

I felt that the whole experience went very smoothly. The aircraft was extremely clean and tidy on boarding. The cabin crew were beautifully turned out very, very efficient and were a credit to Singapore Airlines who are now my favourite carrier.

No frills airline with minimal leg room and no entertainment

Great to have actual hot tastey meal on a flight. Well done

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

Airport lounge for business class is too crowded and not comfortable. Poor foods and facilities. Boarding was delayed. A lot of coughing people in the flight even in the business class, which indicated poor screening and health risks.

Seamless fussy free flight. Great service as expected of SIA.

There’s a reason SIN is on of the BEST airline in the world.

I was very impressed with this airline. The plane was clean. The attendance were nice and it was a great comfortable experience. The zipper on my suitcase broke after I checked it, and they wrapped it all Thailand plastic wrap to prevent it from coming apart during the flight. When I got to Los Angeles, all of my items were safe and still in the bag. That is above and beyond!

Poor. Flight was delayed by 50 mins. Poor quality aircraft. Aged, few parts broken. Bad plane.

I want a refund. I had to switch flights and buy another airline ticket because this one was delayed.

It seems that qantas are trying hard to regain their status as Australia's premier airline. I only flew economy but happy with the service entertainment, food, configuration everything.

We had a medical emergency, needing to get to an emergency room upon landing at LAX. I let the back flight attendants know the situation. One, David, contacted the pilot, who made arrangements for EMT's to be there when we got off the plane. They went above and beyond for us. We didn't have to go through customs, as a customs person came to us and checked us right at the exit of the jet way. Another wonderful woman, a United employee at LAX, perhaps a customer service liaison, took care of our luggage situation, as we weren't going to make our connection to Bozeman. When we came back to LAX to see when we could get a flight to Bozeman, the personnel are very accommodating and booked us on the next flight out, and assigned good seats. It was a horrible flight, physically, from Sydney to LAX, , but the professionalism of all involved was excellent! We are very grateful fir the way they all stepped in and helped during a very unpleasant medical situation. Thank you!!

Very good overall. However, your choices of free movies was limited and there was no music Channel???

We booked with Qantas instead of Delta and we instead flew on American Airlines. American is not our favorite to go on. No leg room and the width of seats are a joke. Your are packed like sardines on American flights.

After already paying for excess luggage prior to flight, i was advised AT check in that i had to pay $816 or forfeit my flight! The lady at the counter was SO rude and had already started offboarding me when i said i would pay it after asking her three times for the exact amount! Have lodged a formal complaint yet heard nothing. Will not ever travel via Qantas again

they ran out of fruit for breakfast and so I just had a yogurt instead. other than that the flight was good

One of the oldest most uncomfortable "lay down" seats I've ever experienced. Old plane and old seats that don't lay flat. The seat back does not even recline - at all. Instead the legrest awkwardly extends to fill the gap between a small cubby into which you must insert your feet/legs. I am 5' 11" and could not lay straight but had to tuck my knees. Ticket was also very expensive. Would not recommend flying business/first on Finair from Melbourne to Bangkok and will not do so again myself.

I liked the service, the menu, and the comfort of the seats! Even tho we were seated by the bathrooms, the reclining seats and movie selection was very good, my husband and I didn’t mind at all
