I would like to report a lost property in the airport. On the last Wednesday, 10th January 2020 I flew from London to Vancouver with a flight number of SQ 728, (seat 25A). Although it was long flight, unfortunately I left my hand luggage on the upper head cabinet. As this was very ordinary bag and maker of Samsonite tagged on it. This was black color bag with a small side pocket on it and inside some books, personal diary and red jacket. There was a small pad lock which includes combination of number to open. Eventually my diary which contains some valuable contact details that might be very import for me.
