As this was our first time flying international business class we couldn't compare it to any other airline. The short flight from Las Vegas to Los Angeles was very comfortable with exceptional service. We had nearly a 7 hour wait for our next flight to Brisbane where we had the use of the Etihad Lounge. This lounge was quite ordinary, we had hoped for more comfortable seating as it was such a long wait. The service was very good for the last leg of our trip, food was delicious. I thought the staff would ask if anything was needed during the trip, but didn't. You have to actually push the call button to get their attention for anything. This might be normal, I wasn't sure. They are very happy to help you with anything of course, once called. On arrival at the airport our bags came very quickly and we were so happy that everything went smoothly at Brisbane airport once we arrived.
