Let's face it: waiting in line for the TSA to scan our carry-ons is probably only second to getting a root canal from a painful experience perspective. So we've learned that liquids and gels over a certain volume will be confiscated at airport security, and aside from the occasional forgotten bottled water in the bottom of our laptop bag, we've become fairly adept at keeping stuff out of those bags that will slow up our time at security.

But beyond these restricted items and ever so quietly, the Transportation Security Administration (TSA) continues to roll out new rules that can affect travelers' experience, slowing the security screening process. One of the latest substances to get additional attention from the agents is powder.

My wife and I know this all too well, seeing our time at security tripled on a recent trip, as the agents removed all the clothing in one carry-on bag to get to a small container of baby powder we'd packed.

It's not that powdered substances are not allowed in carry-on bags, but additional scrutiny is being placed on containers believed to contain powder, including the TSA potentially opening the container to sniff the substance. The rule states that if the powdered substance is over 12 ounces, TSA has the discretion to do additional screening. If the TSA "flags" the powder, they may not allow you to keep it, and it is suggested that you place these items in your checked baggage.

The next time you travel, toss that powder, including medically necessary products, in your checked bag. It will make the TSA adventure a bit less adventurous.
