Which precautionary action for executive protection is not advisable?

Choosing not to use commercial airlines is a precautionary action that can be unadvisable for executive protection for several reasons. While private travel can offer increased privacy and reduce exposure to potential threats, it can also complicate logistics, create higher costs, and limit options in certain scenarios.

Travel by commercial airlines provides the benefit of established security protocols, which can enhance the overall safety of the executive. Additionally, the use of commercial flights can minimize visibility, as various passengers use these services regularly, thus making it more difficult for potential threats to track an individual.

Maintaining a low profile, not publicly announcing travel plans, and the use of armor-plated vehicles are all strategies aimed at enhancing security without drawing undue attention or incurring excessive costs, making them generally advisable measures in executive protection strategies.
