Or put the things that fit into the bin, then take the empty bag into a toilet stall. Wait a bit, and leave it open and empty in the stall.

Open bag, left in a stall? Immediate security alert. You're naively assuming that if it appears empty, it'll be considered obviously empty. But devices that appear harmless are widely used in insurgency/terrorism, it could be a bomb in the lining, triggered by the act of lifting an apparently "empty" bag. And you'll be on CCTV records going in with, and coming out without. Hard to explain.

@WGroleau that's a very easy way to cause a security scare and then get a good cavity search if security notices you doing that

Thank God, the actual correct answer!

@Stilez Wow. Walking with shoes in an airport? Security scare! Throwing a sandwich into the trash? Security scare, could be a bomb! Come on.

@pipe The airport I live near frequently broadcasts a message specifically telling everyone to notify security of unattended baggage.

(The idea of "leaving it in a stall" is of course, totally, utterly, bizarre.)

@WGroleau I think you're missing the point that the correct approach here is to be absolutely transparent. Security personnel has no idea what your intentions are, so any effort to be sneaky or to hide something are going to be seen as malicious until shown otherwise. If you really think this is the right answer, why try to hide what you're doing?

Kind of hard for security to notice what happens in a toilet stall in most airports. Less than a year ago, I stood for fifteen minutes about ten meters from a huge unattended suitcase. Heard at least two announcements about unattended luggage, and watched pilots, security people, janitors, passengers, and flight attendants walk past it oblivious.

@LordFarquaad, I’m not trying to hide anything. OP is the one that asked.

Seriously, this is a really bad idea. 6 quick answers, courtesy of: Scotland: arrest (scotsman.com/news/…). Singapore: arrest (straitstimes.com/singapore/…). Detroit: misdemeanor charge (flyertalk.com/forum/travelbuzz/…)....

... LAX, Manchester UK: terminal evacuation/armed response (latimes.com/local/lanow/…(thesun.co.uk/news/3765601/…)). Paris: zone evacuated (dailymail.co.uk/news/article-4073136/…)‌​. Two of those (Scotland, LAX) involved bags abandoned in a toilet.

Did any of them involve an EMPTY and OPEN bag? OP isn't trying to scare anyone, merely (apparently) trying to avoid attracting attention. (For what it's worth, I agree that telling the appropriate people what you want to do is a much better idea.)

@WGrolea - the better question is, whether they involved an apparently empty and apparently open+fully visible bag, which just happened to also be enticingly placed and abandoned in a security sensitive area. Do you really think anyone should be even slightly encouraged to think "maybe if I abandon it opened enough In a toilet, nobody security trained could mistake this open bag with an opaque frame, solid wheels and hidden parts for a suspiciously abandoned bag........

This is not worth arguing about.

@Fattie obviously, somebody might be trying to blow up the toilet.
