Nut Ban Announcements on Planes Deemed Ineffective by Experts

Researchers find no evidence of airborne nut allergen transmission, recommending pre-boarding for allergy sufferers instead.

Experts from Imperial College London and Aviation Medical Consultancy state that nut allergens are unlikely to be transmitted through aircraft ventilation systems.
Studies suggest that nut ban announcements on flights may create a false sense of security for passengers with allergies.
Passengers with nut allergies should be allowed to pre-board to clean their seating areas, reducing the risk of accidental reactions.
The presence of nut residue is more likely due to consumption on previous flights, not airborne transmission.
Airlines are encouraged to develop clear policies on food allergies and consider carrying general use adrenaline autoinjectors.
