ronb wroteThe suicide bombers in Brussels detonated before the security check. There are crowds as you approach security checks in the Bali airport, so the same sort of problem could happen.
I don't agree ronb...you cannot enter Bali/Jakarta's departure hall without a ticket/boarding pass and all bags are x-rayed just inside the entrance door before approaching the check-in counter.
In many other airports, like Brussels, anyone can enter the departure hall and the security check is done after the check-in counter.
I believe they have changed that procedure already.
