Just want to do a little more clean up so does not smell like urine.

Just want to do a little more clean up so does not smell like urine.

Check in process at the kiosk, crew in flight and overall comfort was good. Food selection could have been better. Flight from Hong Kong to Los Angeles did not have any vegetarian main course option, it was either sea food or chicken. Being a vegetarian I could only eat yogurt and fruit. Most international flights have one vegetarian main course dish which I found missing in Cathay Pacific menu.

Great. Efficient boarding process with the face recognition. Plenty of cabin space for luggage.

As before, my only problem was not being able to download my boarding passes prior to arrival at the airport. Everything else was perfect.

Better. I took an aisle seat this time. Although the overheard compartment above the seat ahead of me kept opening up during flight.

They ran out of food and were offering random food to passengers.

The food and service was great. You have to pay a lot for in flight Internet though which is lame.

Special request meals are really below average. Vegetarian options are very limited if you didn't prebook.

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

The flight was delayed for 30 mins. The overall experience was good.

A few more inches of legroom is all i ask

One of the best Qantas business flights I've had. Quality product

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.

Airline running better than post Covid, proper boarding process now implemented, some aircraft feeling a bit old and tired, crew fine, online experience better.

Five hour flight instead of four hours due to westerly headwinds which wasn’t the fault of Qantas !

The wifi was out. Otherwise it was great flight. Richard, as CSM, was excellent.

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

The Emerits/Qantas flight was cancelled to Wellington. We need a refund. Had to buy another airline ticket. How do we get the refund. Still not in Wellington.

Delayed QF59 flight once again, Qantas doesn't fail in maintaining there delayed departures and arrivals. USB points do not work nor do the power point sockets on the plane, Qantas staff admitted that on the flight. Don't expect to your charge devices. Saving grace, was the ice cream. Bottom line, if you expect to fly to HND and make it on time avoid Qantas and if you're interested in ice cream - visit 7/11.

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?
