The TSA has started a campaign to answer a lot of the “Why” questions that they get from travelers and has produced a series of videos.

Here’s the idea:

It is a national effort to build awareness about checkpoint security procedures so that passengers will be better prepared for airport travel. The campaign is committed to communicating why certain procedures and requirements are part of airport security. The goal is to improve security by compelling airline passengers to be better prepared for the security processes, resulting in less frustration and a more positive experience.

This video explains why TSA asks passengers to show photo ID before entering airport security checkpoints. The bottom line, no we won’t take you word for who you are. No, nor a note from your mother.

This video explains why TSA limits passengers to three ounces of liquid or less in their carry-on baggage. The bottom line is that we would rather that if you carry liquids that blow up that you only have them in small amounts or at least have to pour them all together. It’s all about making you feel safer.

With more than 700 million travelers passing through airport security checkpoints yearly, TSA recently began introducing changes to passenger screening at the checkpoints to improve security, and enhance passenger and officer experience. These changes include: calming the checkpoint environment to improve security, deployment of enhanced technology and improved checkpoint signage at airports to help passengers learn the “why” behind what TSA does and self-selected lanes for passengers (like Family Lanes and Black Diamond Lanes for biz travelers). Because of these changes it has become increasingly important to get the public to focus on what they need to do to get through the security checkpoints before they travel.
