Qantas has admitted that they lost the property of a passenger, believing to have donated it to charity.

Sydney-based lawyer Suzanne Clarke received a phone call from the airline revealing they had found her 22-year-old son's item, but lost it again, the Daily Telegraph reported.

The confession comes after the Sunday Telegraph’s controversial article that the airline auctioned off passengers’ unclaimed lost property, released two weeks ago.

According to Ms Clark, her son had left the CD and DVD folder on a flight from Sydney to Los Angeles in May, and the airline had been uncooperative in her son’s three months of efforts to make contact.

"They believe it has gone to a charity but they can't tell me what charity, or when it went to a charity or any information about the whereabouts of the item because it's now too long since my son's flight,” she said.

"They have offered me a gift voucher for $400 but the items are worth more than $1000. They said they can't reimburse the full cost because it's not their fault.”

Two weeks ago, the airline said that it made every effort to reunite passengers with their lost items, and that it donates hundreds of unclaimed valuables each month to the Salvation Army and Mission Australia in Sydney.

Neither of these charities has received donated items from Qantas in over a year, the Daily Telegraph reported.

Do you think Tristan, the 22-year-old who lost the $1000 worth of CDs and DVDs, should be fully reimbursed by Qantas?
