Johanna Ganthaler, a pensioner from Bolzano-Bozen province, had been on holiday in Brazil with her husband Kurt and missed Air France Flight 447 after turning up late at Rio de Janeiro airport on May 31.
All 228 people aboard lost their lives after the plane crashed into the Atlantic four hours into its flight to Paris.
The couple had managed to pick up a flight from Rio the following day. But Ms Ganthaler died when their car veered across a road in Kufstein, Austria, and swerved into an oncoming truck. Her husband was seriously injured.
