John F. Kennedy Jnr's sister-in-law spoke by phone to a Hong Kong friend just before boarding the fatal flight, it emerged yesterday.
Lauren Bessette, who had hitched a ride with her sister Carolyn and her husband, chatted to Irene Chu.
The pair, both graduates of the University of Pennsylvania, arranged to have lunch in New York, where Mrs Chu is staying.
Mrs Chu's husband, Victor Chu Lap-lik, had employed Bessette at his investment company. Mr Chu said yesterday: 'Lauren and my wife talked on the phone on Friday afternoon and they were going to get together this week,' he said.
'Lauren was telling my wife how she was going to Martha's Vineyard and they would get together when they got back. She was rushing off,' he said.
Yesterday, authorities gave up hope of finding any survivors, almost 48 hours after the plane disappeared from radar on a flight from New Jersey to the island of Martha's Vineyard.
