I just flew Air Canada. When we were leaving Sydney on the 15th of September we were waiting for an hour on the taxi way because there was too much traffic to depart. The pilot came over the intercom and said they were going to switch off engines to save fuel.We still made it to Vancouver half an hour early though despite leaving over an hour and a half late.
Arrived back on Monday morning. Left Vancouver on time but got held up by head wind and arrived late. Had to go through the spray process as well once we arrived. Sitting on the plane for another 15 mins when you just want to get off after a 15 hour flight.
I will write up a full trip report with photos and videos when i get some time.
