What is required for each additional row of three passengers regarding exit cards?

For each additional row of three passengers, one exit card is required. This is in line with the safety protocols followed by Southwest Airlines, which ensure that there is adequate communication regarding emergency exit procedures for all passengers on board. Each exit card provides crucial information on how to operate exits and what to do in case of an emergency, thereby enhancing the overall safety of the flight.

This requirement reflects the understanding that having one exit card for every three passengers is sufficient to effectively convey exit information without overwhelming the passenger with too many cards, thus making it easier for the crew to manage safety instructions. The main goal is to ensure that all passengers are informed and prepared without unnecessary duplication or confusion.
