This is just one of the honest deeds of SIA cabin crew which involved the largest sum of money. It was not reported in the press,I believe. One of my visitors gave me this report:
Many years ago a paper bag containing more than a million SIN dollars in foreign currencies was left in the seat pocket of SQ flight arriving into SIN from TPE. After passengers had disembarked the crew did a routine check of the cabin and found the bag with the monies in the seat pocket of the Economy cabin. The crew-in-charge surrendered the found items to the company.
