After already paying for excess luggage prior to flight, i was advised AT check in that i had to pay $816 or forfeit my flight! The lady at the counter was SO rude and had already started offboarding me when i said i would pay it after asking her three times for the exact amount! Have lodged a formal complaint yet heard nothing. Will not ever travel via Qantas again

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.
