What can passengers do to enhance their comfort related to cabin atmosphere?

While notifying the crew of discomfort related to temperature or air quality is indeed a valuable option, adjusting personal air vents actually provides passengers with a direct way to enhance their comfort regarding cabin atmosphere. Personal air vents allow passengers to control the airflow directed toward them, which can improve comfort by adjusting the temperature around their individual seat. This feature enables each passenger to personalize their environment, taking into account their own preferences for airflow and temperature.

Conversely, while informing the crew of any discomfort is important for overall cabin environment management, it doesn't provide immediate relief like adjusting personal air vents does. Passengers are also not empowered to request different meal options or change their seating arrangements in a way that pertains to the cabin atmosphere. Thus, passengers can take immediate action to enhance their comfort by adjusting their personal air vents.
