Airline reviews

Overall, it was a very good experience. I would have given it a 10/10, especially based on our flight from SFO to Melbourne. The cabin crew on that flight were wonderful and incredibly attentive. They took extra care when setting up our beds so we could sleep comfortably without being disturbed. Dinner was served promptly and smoothly. I woke up quite late, when the flight was already preparing for landing, and the crew still made sure I was taken care of. They brought me English tea in a proper cup, and when it was time to prepare the cabin for landing, they thoughtfully transferred it into a takeaway cup so I could continue enjoying it along with some breakfast. Those small, thoughtful gestures made the long flight feel much more comfortable and special. The service from the SFO to Melbourne crew was truly excellent.

Great food and good entertainment options for the long flight.

Loved the food and beverages available, spacious economy class, excellent entertainment

Very good overall. Highly recommend for all flying to Australia

We had bulkhead seats in a A380 in the upper deck in seats 31 D and E. Storage was very limited other than in overhead bin - which is not within reach when in seat. Yet paying same price as others in premium economy who have a lot more storage within arm’s reach. Seems very unfair.

Excellent as always, I won't fly to Australia, and back to the US on any other airline. The flight crew is always top notch, and have a way to make one feel extra special. Thank you for your service, I would rate Qantas Airways a 10+.

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

Terrible. 6 hour delay with no explanations and only 15 dollars in food credits. A disaster. I'll just leave it at that.

It was so hot on the plane mixed with being quite turbulent and a rough landing. We all felt very nauseous for hours afterwards. Crew were lovely though.

Ease of boarding. Staff were friendly and helpful. Food was good. In flight entertainment great.

Uncomfortable plastic seats even in premium economy. No free wifi. Even paid wifi was spotty to nonexistent. Bad food. Much worse than economy on foreign carriers like Qantas.

Good flight. However, when booked flight with United, assumed the layover included by United in San Francisco of 1 hr and 40 minutes was sufficient . Not so and would recommend at least 2 hours or more. Needed to go through US immigration (very long lineups), then pick up bags, take all the way to another terminal, running because we did not have sufficient time. We made the flight because they held the door for us but luggage didn’t follow.

It was good but only meal served is very less. Meantime good to add rice and chicken in one of meal

I found the staff to not be very attentive at all. When paying for Business Class you expect a certain type of service and that was not found. They were almost rude even

Great. Food going from Australia to the US was better than other way around, but still needs improvement in terms of quality and quantity!!!

Flight departed owing to SFO TSA delays as well as incoming flight running late I know these delays are commonplace but when you’re flying long haul international the least that could be done is priority being given to customers in this situation I raced to the gate the plane was still there but NO UNITED AIRLINES STAFF in the surrounding area could seemingly provide effective support This coloured my view of flying with UA The actual flights were good

Crew seemed annoyed by the fact we were there. Very unpleasant

Due to a cancelled flight the day before this flight only had 44 people. Best flight ever on international route. Food getting better. Can United provide fruit ex apples and bananas for snacks? Crew fantastic.

Honestly didn’t like anything. Crew was in rush . Food was ok and there was no whiskey. Have to pay extra $ if you want to drink whiskey . They only provide wine and beer.

Compared to other international Airlines the infotainment system is need of overhaul. Doesn't have music it's got a limited selection of movies but I was impressed that an American airline was showing the documentary on John Farnham an Australian singer!
