How many hours prior to departure must a special meal be requested?

The correct timeframe for requesting a special meal prior to departure is 48 hours. This requirement is in place to ensure that airlines are able to accommodate passengers' dietary needs and preferences effectively. It allows sufficient time for the airline to plan, prepare, and procure the necessary ingredients to fulfill the special meal request.

When a passenger requests a special meal, such as vegetarian, kosher, halal, or gluten-free, the airline needs to coordinate with catering services, which often have strict schedules and inventory management systems. By setting a 48-hour notice period, airlines can ensure they maintain the quality and safety of the meals provided onboard, minimizing the risk of last-minute issues.

This time frame is a standard practice within the industry, aligning with many airlines' operational procedures and catering arrangements. Other time frames, such as 24, 36, or 72 hours, may not reflect the typical operational needs and logistics involved in preparing special meals, which is why 48 hours is the established norm.
