Pretty excellent. I don’t know what the pilot could have done better with the bumping ( there was a storm) nor what happened to my ears coming down into bendigo. It doesn’t happen coming down into Sydney just the return flight. I wonder why?

Pretty excellent. I don’t know what the pilot could have done better with the bumping ( there was a storm) nor what happened to my ears coming down into bendigo. It doesn’t happen coming down into Sydney just the return flight. I wonder why?

Loved the staff. The economy seats could have been bigger.

Airport and crew experience was excellent. We had to queue for the runway - no one’s fault, but it did mean we were 30 minutes late leaving

Overall good experience with flight and airport wheelchair staff. Also got Indian food in the flights

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

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.

It’s a two prop flight so I had problems with my ears on re- entering ! But otherwise fine

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.

The food was terrible. And the flight attendants were very rude. One flight attendant wouldn’t help a passenger lift their carry-on. Another flight attendant wouldn’t give a man an extra blanket. And they walked by not even looking at the passengers to see if they needed a glass of water.

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.
