Flight Incident Overview
On August 1, a China Southern Airlines flight traveling from Wuhan to Urumqi experienced an unusual in-flight disturbance after cabin crew distributed 100 ml packs of prune juice to passengers. According to passenger accounts shared on social media, the beverage acted like a strong laxative, prompting a rapid scramble toward the aircraft’s two lavatories.
Passenger Reactions and Reported Effects
Multiple travelers posted that they had mistaken the prune juice for ordinary grape juice and consumed it without hesitation. Within minutes, queues formed outside the limited toilets as stomachs “started gurgling” throughout the cabin. Some passengers said the gastrointestinal effects persisted after landing, with at least one individual racing to an airport restroom and later needing another bathroom visit at a hotel. ) ).
Airline and Staff Response
China Southern Airlines staff later stated they could not fully verify the specific incident and described several online reports as inaccurate or exaggerated. The carrier noted that prune juice is not served on every flight and that typical beverage options include coffee, regular fruit juice, soy milk, and water. No formal complaints of diarrhoea were recorded, and the airline has not announced an internal review, catering audit, or investigation.
Medical Explanation and Data
Prune juice is known to contain high levels of sorbitol, a sugar alcohol that draws water into the intestines and can produce a laxative effect. A doctor referenced in the reports indicated that ingesting more than roughly 10 g of sorbitol may trigger diarrhoea in healthy individuals.
Implications for In-Flight Service
The episode highlights potential risks when serving beverages with known laxative properties on densely seated aircraft with limited restroom capacity. It underscores the importance of clear labeling and passenger awareness, especially on routes where cabin crews may offer a variety of drink options without detailed ingredient disclosures.
