The family of the Auckland man who died on a Jetstar flight say he had a pre-existing heart condition.
Robert Rippingale died on a flight from Singapore last week with his girlfriend, Vanessa Preechakul, as he was coming back for his parents' combined 50th birthday party.
The 31-year-old's father, David, said his son was born with a hole in his heart but said his family were waiting for the results of the autopsy before they made up their minds about how he died.
"The police told us he choked on the food on his flight, but he had a heart problem so we think it might have been that. He was born with a hole in his heart and had that fixed when he was 6, and he's had the valves done a couple of times since then.
"We're just waiting for the answers now."
