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.

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.

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

Overall the airline tried to give excellent service. The wheelchair service was bad at SFO. My baggage was also delayed but I thank them for taking the trouble to find it and deliver it to my home.

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.

Overall were very good and I was satisfied w/ all the food and services.

First time flying with Singapore airlines and I’ll give them two thumbs up 👍 👍

Food was served to different people at different times and it wasn't clear why. The crew apologized for the wait. But it felt odd and inconsistent. They could use charging ports on each of the seats. Mine didn't have any. Also, they could've offered more snacks. It was a 12+ hour flight and no snacks were ever offered. Everything else was OK.

No frills airline with minimal leg room and no entertainment

The consistency with Singapore Airlines is fantastic. Crew are always brilliant and food delicious in business class

Wish the underseat compartment don’t have a restriction, can fit a personal item such as backpack fully like most Boeing

Boarding was effortless, the food was outstanding, the seats in Premium Economy were extremely comfortable, and the staff and crew were excellent.

It was ok, but not what it was like 20 years ago

We had a cancellation due to weather, but the American Airlines staff was very helpful. Once we got on a plane, the trip was great.

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!!

Loved the food and beverages available, spacious economy class, excellent entertainment

Helpful staff when I felt unwell. Qantas need to have an audio/music channel so you can listen to various music/.artists

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

We had bulkhead seats in a A380 in the upper deck in seats 31 D and E. Storage was very limited other than in overhead bin - which is not within reach when in seat. Yet paying same price as others in premium economy who have a lot more storage within arm’s reach. Seems very unfair.

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.
