Edit to clarify regarding international travel: You don't go through anything OTHER than our TSA security checkpoints when flying internationally. No dogs, just people. They're looking for certain things, and snacks being brought onto the plane is VERY common for these super-long flights. You just try to tell that little old lady she can't bring her noodles or na'an bread on the plane!
Seriously, though, in Taiwan drug offenses carry a penalty of death. So, if you have any leftovers by the time the plane's within a half hour or so of arrival, flush 'em. On all of the international flights I've taken they will put up the flight statistics (altitude, ground speed, outside air temperature, time at departure and destination, and so on) on a screen, so you can see how far you are from touching down.
Anyone ever made brownies and brought them through airport security? Really bad idea? I'm thinking that in theory it could be nice for a flight to China I have coming up.
Hey, now that's a REALLY good idea! FUCK I wish I'd thought of that. China is a really long flight, and that's just flying out of SFO. The only problem would be if you went through customs (which you won't heading out) and a dog hit on you. There are no dogs going through check-in and all of that, so as long as they don't obviously stink and as long as you don't do what I did and bring along a can of soda, you should be golden (they took my soda).
