When Frank returned to Schiphol Airport on Monday, his friends and relatives were overjoyed to see him.
'When he didn't come home after his evening shift on Friday, I called the airport-but nobody had seen him for hours,' his mother said to reporters.
Frank explained that he was very lucky because it is possible to die of cold in the hold of an aircraft.
He apologized to his boss for sleeping at work instead of working, and promised it would not happen again.
'During the flight I was petrified. I thought I was going to die!' said Mr Vreede. 'I wouldn't want to do it again. Next time, I'll catch a regular flight!'
