Nice friendly staff and crew. Love the 787 flight. Get meals and lots of drinks!

Service was excellent and they’re very helpful and nice

Overall the plane was good and the crew great. The big disappointment was the skycouch. Maybe it would be good if you were a parent with 2 small kids travelling but as a couple it's hopeless. It's impossible for 2 adults to lie down so one ends up sitting. We split our time with one lying and the other sitting. We both got more sleep sitting upright. We will never book one again and don't recommend it to anyone.

Aircon set too high so VERY warm and VERY uncomfortable.

Lost my luggage and brought someone else luggage to my airport.

Not entirely positive. It’s frustrating that everything is done through the united app. One of our flight attendants on our trip from San Francisco to MSP continually had trouble hearing people so she flipped her hair into people’s faces

I flew United from San Francisco to Auckland. My connecting flight from Auckland to Christchurch was canceled with no explanation. I was finally told the cancellation was due to fog. Even though it was clear when we landed. I am from San Francisco, I know what fog is! And I didn't see any fog. I was told the next available flight was 7 hours later. Unacceptable, they should have had a flight ready to go as soon as it was deemed safe to take off.

Our original flight was cancelled from SFO to AKL on 6/16/25. So we had to stay overnight at a hotel after a 12-hour layover plus 3-hour delay before the cancellation. Then had to fly to LA and then to AKL the following day losing an entire day of our vacation in NZ, that we can never get back.

Full flight. Flight attendants were harried. Otherwise, fine for the typical cramped seating conditions in coach.

Great! Flight was delayed by 30 mins but all was great. Thanks.

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.

Mostly good. Flight was crowded but Airline personnel were very friendly & accommodating. It would be good to have savory snacks rather than just sweet Biscoff cookies.

It was a typical flight. We had a delay which seems to be the normality now. And we had no in flight service due to conditions.

Flight attendants on this flight were very attentive and friendly

After we landed we sat on the tarmac for 1.5 hours waiting to get to our gate. Ridiculous.

Food should be better quality. Video screens have poor resolution and the library of movies is poor. The other airlines are much better.

the trip to madrid was uncomfortable with my legs touching the seat in front of me

The plane was late, when we did board the plane was as cold as a freezer. I was freezing the entire flight, no blankets. Lost miserable flight I’ve ever had.

My flight was delayed for 17hs because the pilot forgot his passport!!! What a joke. AA used to be a great airline, now I have to think twice before flying with them again.

Terrible. Flight delayed for more than 8 hours with only a $12 meal voucher provided for the inconvenience. The airplane did not have breaks on arrival yet they still made us go through the motions and board on time knowing we could not take off then sit for 40+ minutes before having to get of the time. A complete waste of my time. I cannot believe they can stay business with these shenanigans. I’ll avoid this company like the plague moving forward as the lack of accountability is disgraceful.

This was the best 2 flights I have had with American out of SGF. Great crew both flights.
