There's not a lot of O/D traffic to Dubai from Indonesia... it's mainly labour traffic at low yields. GA to Saudi Arabia is to serve the labour, government and religious pax.
GA left Abu Dhabi years back after they cut most of the European flights leaving FRA, LGW and AMS to be served through SIN/BKK instead on the 744.
Most of the traffic on EK to Jakarta are cargo, and Europe through pax... and LOTS of CGK-KUL/SIN pax (since they're cheap and the holds have quite some cargo already!)
Garuda has no A332, only A333. Besides, Garuda is waiting for 3 more A333s and 6 772s... The A333 will be the principle medium hauler with the 772 for long hauls in general. The 3 extra A333s will replace current 4 742 routes... (Saudi Arabia, Hong Kong and Japan)...
When losing situational awareness, pray Cumulus Granitus isn't nearby !
