A trip to a foreign airport or another airport is not a real trip without plane spotting! Yes, I went spotting at Bali Airport and caught some cool planes! Enjoy the pics!
There’s 6 of them, and it doesn’t only carry the Vice President. Could be anyone important in the government. It’s only Air Force Two with the VP onboard.
The Secretary of State’s currently in Bali for the G20 meeting there iirc- he’s an important Cabinet member there on official business, so he generally gets to use the C-32 in the course of his travels
In context, Jetstar usually operates their A320 on flights between CNS, ADL, DRW and etc. Some airlines operate narrow body aircraft on some medium haul international routes, like the ones I just said. 737 Fam and A320 Fam can operate these routes very easily so it makes the airline choose this aircraft to operate that route.
