Former airline cabin crew Dee and Tania were interviewed on the Richie Allen Show this week about the very real dangers of aerotoxic syndrome which the airlines don't seem to be taking seriously.
This is not only an issue for cabin crew and pilots but for all airline passengers on commercial aircraft except maybe on the Boeing 787 which is the only commercial passenger aircraft that does not ventilate the cabin with bleed air.
It seems likely that sooner or later the airlines will face massive damages claims and will be forced to pay compensation to affected passengers and crew.
