2- Children are the enemy. When given the option, always go for the childless line.
3- The **@#&!^ng laptop has to be run through separately. People ignoring this rule can double your wait time…so if you spot someone making this rookie mistake, always say something.
4- The ubiquitous pat down is part of life. Just hold your head high and own it.
5- Always make sure you grabbed your hat and identification! Learned this the hard way.
