Well, this is something i want to talk about. I just came back from China-Beijing, they security there is tight, and they check things through. It maybe part of the olympics.
When i first landed back in singapore-BT, i realized the security is very loose, i actually able to brought 5packets of cigarette !! I think its ridiculous, they did not scan all of the bags when passenger is leaving. I still remember last year when i came back from china, that was in T1 or T2, the security is tighter.
Really BT is very BUDGET!
perhaps they just close one eye nia..
to further test them, try to bring in weapons (e.g guns)..
