The experience with United Airlines was excellent; however, the experience with Houston Intercontinental Airport (IAH) was horrible. Although our flight departed from Terminal B, we had to go through security in Terminal C and then get on a train for travel to Terminal B. Additionally, there was significant walking required to get to the boarding location.

The experience with United Airlines was excellent; however, the experience with Houston Intercontinental Airport (IAH) was horrible.

Additionally, there was significant walking required to get to the boarding location.

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!!!

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!
