At least to airport employees outside the US. After our recent trip its now 30% of our international trips where I have gotten pulled aside at an international airport for additional screening (About 20% of total international flights). I'm at maybe 2% domestically. My wife, who is standing next to me in all these security lines, has been pulled aside exactly 0 times. I wear the same clothes as a domestic flight, have the same luggage - just standing normally in line so I'm still trying to figure out why I look like a bad guy or if I am just filling some sort of quota
