A woman is suing the airline Emirates, claiming she collapsed after being refused adequate water on a long-haul flight.

Lina Di Falco, 54, has told Victoria’s supreme court she suffers constant ankle pain from the injury she sustained on the 2015 flight from Melbourne to Dubai after being refused additional water.

Di Falco said she asked repeatedly for water after boarding the 15 March flight but only received one glass with her meal more than an hour after the plane took off.
