Australian Company
9+ Hours = "Employee can elect to travel business class"
So Sydney -> Singapore = Economy due to 7.5 hours.
Sydney -> Hong Kong = Business due to 9 hrs 5 mins
I am yet to fly business yet. 3 trips so far (all over 9 hours) however I decided it was best to fly 1 in economy, 1 in full fare economy (rule due to it being a sales conference - all staff in economy), 1 in Premium Economy.
I should do the next trip in business so at least I can hit gold status.
