When is a Delay Snack Kit required to be available on board?

The requirement for a Delay Snack Kit to be available on board is linked to the anticipation of long delays that could impact passenger comfort and well-being. When flights experience significant delays on board, such as during extended taxiing, weather-related holds, or other operational interruptions, it is crucial that passengers have access to food options.

To enhance the flying experience and fulfill the airline's duty to care for its passengers, having a Delay Snack Kit readily available during these circumstances ensures that crew members can provide necessary nourishment. This practice is aligned with customer service protocols and enhances safety by preventing passengers from experiencing undue discomfort caused by hunger, especially in situations where a delay could extend for several hours.

Thus, the correct reasoning is that the Delay Snack Kit is specifically required when a long delay on board is anticipated, ensuring that passengers are cared for effectively during their wait.
