Have just done SYD-SF0-MCO- (prior to spring break in the US) LAX-SYD, all flights except for the LAX -SYD leg were full! LAX-SYD was probably around 80% capacity. I was told prior by my agent here in Sydney that the SYD-SF0 flight was virtually empty, which left me somewhat surprised when checking in i was informed that the flight was full & had been full for a number of weeks.
