Downwards,
Then you should please use the airlines' correct name and do not abbreviate as "Aboriginal Air Services". The correct name is..."Ngurratjuta Air and Ngaanyatjarra Air and Pitjantjatjara Yankunytjatjara Air and Janami Air trading as Aboriginal Air Services"
FYI even people who work and own and use these airlines refer to them as "AbAir" and "Pee Why Air".
It's just handy abbreviation not an evil attempt by the master race to take over the planet.
