Which of the following is NOT part of the Blue Stripe program's focus?

The focus of the Blue Stripe program primarily revolves around improving passenger experience through aspects such as signage visibility, passenger flow efficiency, and pathway clarity. These elements are all about enhancing navigation and ensuring that travelers can easily find their way through the airport.

When considering security delays, while they are an important aspect of overall airport operations, they do not directly fall under the specific objectives of the Blue Stripe program. The program aims more at optimizing the physical and visual aspects of the airport's environment to make the journey smoother for passengers rather than addressing operational delays such as those caused by security procedures. Hence, security delays are not a direct concern or focus of the Blue Stripe initiative, making this the correct answer in contrast to the other choices, which are indeed integral to the program's mission.
