So, even in-transit passengers through the US have to clear customs just to get on a plane to elsewhere (assuming that someone were flying SYD-LAX-YYZ)?
I can see why people don't want to transit here. Going through HKG on the way to SIN was very simple...another security check, but no customs to clear. How silly.
Agreed.
I encourage people not to transit the US if they can help it.
