Limited food options. I dont like chicken or even fish but that’s the only option. Sad to say not impress

Really great service throughout and the food was really nice. I can highly recommend thank you very much.

I had ordered vegetarian food. What I was presented was extremely dissatisfying and not up to the mark. I pretty much did not eat entire 19 hours. For.an airline voted as best in business, it was extremely disappointing. Seats were not comfortable to sleep. Entertainment system didn’t have much choice. WiFi didn’t work for more than half the time. Cabin crew were also difficult to understand. A bit of diversity like Emirates crew would go a long way.

A little more room from the reclining seat in the front of me.

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

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

Pleasant business class flight experience with good onboarding experience. Flight service team was excellent with usual book-the-chef menu available

Food was just okay, need to improve for other menu variations

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

I was in a middle seat where I felt a bit too cramped otherwise the trip was good

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

Great food and good entertainment options for the long flight.

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.

I never flew with alliance. Kayak is a joke and none of the flights or times were correct. Won’t ever use kayak again

I missed my flight due to unforeseen circumstances It was, however , an excellent price !

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

Very good overall. Highly recommend for all flying to Australia

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

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.

Good check in and helpful staff. Delayed for 1 hour. Took about 45 Mins to get baggage’s at DFW . Food was average ( Hindu meal ) . Overall it was good experience
