Heightened security at U.S airports (and overseas?)

[500N]

I am no expert but I flew not long after 9/11, Aust to US direct on either Emirates or Qantas.

Apart from triple checking ID's (more than one) at counter and before boarding, checking VISA at counter, all bags
- both those going into the hold and carry on were inspected, questions asked etc.

That's all I can remember but it made checking in a PITA.

Note sure they can do much more than that but Aust and the US get on so if they ask, we will do. Not sure what other countries would do.

Edit
As per below, other stuff goes on as well that we don't see !
