Singapore Airlines became the first airline to operate the Airbus A380-800 on 25 October 2007, after a series of delays. The airline placed orders for nineteen A380s with six options. The first flight was a return trip from Singapore to Sydney, with a flight designation of Flight 380 to signify the first commercial flight of the A380. To mark this moment in aviation history, SIA auctioned all the tickets in a special agreement with eBay, beginning on 27 August 2007 for two weeks, and donated all the proceeds to charity. Close to $1.3 million was raised for charity through the auction.
