HCMC
I am not sure if they have changed the crewing, but last time I was in the top end, the JQ crews would operate HCMC/DRW/SYD with a 3 hour layover in DRW. Disappointing thing was that the HCMC crews did not have a crewroom. The only place they had for the layover in DRW was to try and sleep on the aircraft
