Emergency Services reported three flight attendants were exposed to a white powdery substance prior to boarding. The substance has not yet been identified, there are conflicting reports. Works are underway to identify the substance.
The airline reported a powdery substance was observed occasionally throughout the flight, one flight attendant was taken to a hospital, examined and discharged, the flight attendant was feeling fine the following day. The substance was identified as a de-icing agent that got into the ventilation system while being de-iced in Seattle.
A passenger reported the captain announced about one hour into the flight that a mysterious white powder was leaking from the air conditioning vents, the captain suspected it was the result of de-icing fluid sucked into the air conditioning system and powderizing on its way into the cabin, the substance likely was non-toxic.
The occurrence aircraft is still on the ground in San Jose 37 hours after landing.
(Editorial note: at this time it is unclear whether there is a causal link between the cabin crew feeling unwell and any leakage from the aircraft, we rate the occurrence an incident - should a causal link become confirmed, the category will be changed to accident).
