Which of the following techniques is NOT listed as a method to influence the passenger experience?

Social media engagement is not typically categorized as a direct method to influence the passenger experience in a physical or immediate sense within the airport environment. While social media can play a supporting role in enhancing customer service and communication, it does not create a tangible or sensory experience for passengers who are physically present in the terminal.

In contrast, the other techniques listed, such as airport ambassador programs, calming music, and therapy dogs, all provide immediate and direct interactions that can significantly affect passengers' comfort, emotional well-being, and perception of their travel experience. Airport ambassador programs involve active engagement with travelers, helping them navigate the airport and providing personalized assistance. Calming music serves to create a serene atmosphere, aiding in stress reduction. Therapy dogs are known to improve emotional health and reduce anxiety through physical interaction. These options target the experience during the passengers' time at the airport more directly than social media, which tends to be more about communication and brand presence rather than the immediate airport environment itself.
