Really nothing.

Boarding was slow and people were standing in line for ages before they started to let passengers board. Once boarded, flight was delayed over an hour so we just sat there on the plane. We were sitting in the last row where extremely cold air was just blowing directly at us the entire flight! We asked a few members of the crew including the manager and were told that that's what happens when you're close to the door. It was the MOST UNCOMFORTABLE flight of my life!!! I will never fly Qantas again. They were a complete nightmare and definitely the low point of our wonderful vacation.

People were allowed to be on their laptops and watch movies but we were not allowed to have our phones out to watch movies on our phone. That was not cool for those of us who did not bring laptops and downloaded all our movies and books to our phones. The plane was also freezing cold and the blankets were thin and small. No wifi that worked in Shanghai either for American service providers.

The checkin counter experience was not good. I had business class tickets but was checkin at an Economy counter resulting in my boarding pass not being for business class so when I went in to immigration lines and throughout the rest of the process I did not receive priority that Business class should have received. In addition when I enquirer about TSA preaplroval at the counter I was told Chicago does not have preaplroval at Terminal 5 but in reality passengers with TSA-pre were being sent through the lines without having to take off their shoes and laptops etc. overall the checkin process should have been much more informative.

Our first flight to LAX was delayed by 7 hours so we spent the day in Sydney airport, spending more money on meals that hadn’t been planned. Because of the delay, we missed our connecting flight from LAX to JFK. The flight we were re-booked on was also delayed for mechanical/paperwork issues so we arrived back home in NYC 8 hours later than originally scheduled. This caused us to spend more money on a taxi since it was too late to take public transportation. it also made it difficult to settle back in at home because both my husband and I had to get up early for work the next day and we missed several hours of unpacking and cooking time we would have had had our flight not been delayed.
