New aircraft and flight was running on time, but adverse weather conditions meant we were unable to land on the first two approaches. Third attempt resulted in a very smooth and safe landing.

New aircraft and flight was running on time, but adverse weather conditions meant we were unable to land on the first two approaches. Third attempt resulted in a very smooth and safe landing.

Very good it will be my choice of airline while in Australia.

Very friendly staff. No food service and no entertainment. Only 1hr 20min flight

I bought flights in August and there wasn’t a flight in the system

Our 6.30am flight was boarded then cancelled to fly at 10.55am . We were flying to Brisbane to attend a funeral at 12 noon an hour away . This means missing the funeral due to unreliability of Virgin . Unimpressed !!

Virgin has always provided a smooth and comfortable flight. This one was no different. Seats are comfortable. Staff are great. This is my favourite airline.

Virgin changed the flight to an Alliance flight. Smaller plane, tea coffee and water the only refreshments available and not sure what happened to the extra money I paid to sit in a selected seat with extra leg room. This is obviously a regular switch as it happened on our flight there and back. Do not recommend.

Cramped, crowded flight, with no complimentary food except coffee, tea, or water.

Check-in was good and efficient, Boarding was quick and easy. Didn't like the entertainment side of things requiring your phone to connect for a screen, my eyes are bad enough to use my phone more than I already do. Trip was comfortable and baggage claim was good. If coffee and tea were free, then why not a soda or juice as well, its not like its an alcoholic drink.

The flight was delayed by 45 minutes, but boarding, actual flight, and crew were great. However, there was Zero free food and only water, tea, or coffee to drink. Everything else was for sale. No onboard entertainment but it was a short flight.

Small twin prop plane. Basic flight. Food was half a chicken & pesto sandwich. As the flight departed after 12pm alcohol was available. No on board entertainment. No wifi services.

I liked the refreshments as the flight was short and the free WiFi. The seats were comfortable.

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

My experience was great overall. Tanya was particularly friendly and helpful the entire trip. I was very pleased with her customer service skills. The plane was an older aircraft but the entire way was comfortable with barely any turbulence at all. Qantas should speed up its fleet renovation. Totally recommend using this airline.

Flight was canceled. I was not alerted. It was only kayak that alerted me

I love flying with Qantas. There was no onscreen entertaining on this flight, and only a snack provided (not a meal) but still better than Jetstar or Virgin (in my opinion) so still happy.

Wheelchair assistance to move through the terminals and to/from the plane door was excellent. No vegan snack on the flight, only something with salami and cheese in it.

Boarding was over 3 hrs late and we didn’t land until almost 1:30am

It’s a very long flight and there are so many people on board. Perhaps a warm washcloth now and then to freshen up

The plane was delayed about 3 hours so anything else is immaterial
