One travel catering expert explains that while there is speculation that airlines might serve stale food to passengers, they only provide fresh meals prepared between 12 and 72 hours in advance. This timeframe allows for proper food preparation, packaging, and delivery to the aircraft while maintaining freshness and quality.
The truth likely lies somewhere in the middle. Airlines may not serve truly "old" food, but the definition of "fresh" can vary. Some items, such as sealed beverages or packaged snacks, may indeed be reused on subsequent flights if they remain unopened. However, perishable items are typically discarded after each flight to comply with health and safety standards.
Ultimately, how airlines handle unused in-flight food remains a topic of debate and varies by carrier. If you’re concerned about food freshness as a traveler, you can always inquire about the preparation date of your meal or opt for sealed, packaged items.
