Business class points redemption - good value for points paid, dubious value if out of your own pocket, domestic class business product okay for this length of flight. The flight left and arrived on time, crew were good, aircraft was a bit old and tired, but still miles ahead of their competitors in Virgin and Jetstar.

Business class points redemption - good value for points paid, dubious value if out of your own pocket, domestic class business product okay for this length of flight. The flight left and arrived on time, crew were good, aircraft was a bit old and tired, but still miles ahead of their competitors in Virgin and Jetstar.

Was bumped to a later flight because of inefficiency on part of the airline.

Very good as always, stand out airline. The passengers whom choose to stuff baggage that otherwise should be checked-in is a real bother but that's not the airlines doing. A real frustration that passengers just don't want to check-in luggage. This is a pet hate unfortunately.

The old Plane had not been cleaned properly in a long time.

Great flight and attendants. Seating is a bit weird. The extra price seats aren’t too worth it.

Too many passengers are bringing on too many large items as part of carry on baggage where it should be checked in. This is not the fault of Qantas but the stupid mindset passengers have now about trying to bring anything and everything on as carry on luggage where it should be checked in.

Plane a little late departing, but not an issue. The pilots humour when he said “I will try to make up some time…. I know a few short cuts to Adelaide” made the passengers chuckle. This is what makes Qantas “Australian”.

The staff we fantastic and seemed to work very well with each other

IFE didn't work. Wifi didn't work but they eventually managed to reset it. Our original flight was cancelled, so rebooked onto new flight seated apart from travel partner.

No individual entertainment screens on this flight. Would have been nice to know beforehand.

Boarding was great, and the crew were very friendly. The seats must have been a bit on the older side and you could feel some of the seat components through the padding. Also, the plugs did not work on the row's entertainment screen or charging ports. Checked bag was transferred for connecting flight, and we appreciated how early we had the connecting gate information.

It was Swiss. Our kosher meals were literally frozen solid and therefore inedible, and the crew didnt care.

Food was great. Staff was phenomenal. Seats were a bit hard and could use a lot more entertainment options as far as movies to choose from. WiFi was good. Overall great trip.

The flight was delayed, they didn’t even have water for the toilets or for drinks

It’s always a great time flying with united airlines.

Very old flight - time to retire it for newer airplanes

2+ hours delayed Outlet in row 12 did not work Tv monitors did not work Lights kept off the entire flight for at 5pm-7pm flight

Seated dude next to me even though lots of empty rows. But main thing was we sat on the tarmac after landing for 30 minutes because of, in the words of the dude who sat next to me, “operational incompetence”. We got changing directions about where to pick up gate checked bags. Pilot and flight attendant were awesome though.

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

Tastless food and too obvious lack of enthusiasm for service in the economy vesus business class
