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

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.

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.

I got upgraded from economy to business, and the experience was outstanding

It was very nice. I will try to fly with Qantas whenever I can.

The flight was good, long obviously but smooth. The seats are pretty small, definitely notice a difference for long haul compared to Emirates or Cathay Pacific it’s more like medium haul seating for space. Food options were good, children’s meals were good for my fussy 3yo.

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

Better food, hotter coffee, otherwise it was a very smooth and reasonably comfortable flight.

After flying Quantas (Prem Econ - SYD-SFO) which was Spectacular, we boarded AA flight SFO/PHL.. Prem Econ was NOT available on this flight so we were stuck in Econ - even though we paid $2600 EACH/ONE WAY for this ticket. I even had to BUY extra legroom seats - this AT LEAST should have been included on the AA flight. There were no screens in seatbacks, forcing passengers to use phones for entertainment. No water bottles were provided - only cups of water. The Quantas flight was FAR superior to the AA flight - even though we purchased Prem Econ for the FULL trip....
