Do courier flights still exit?
I remember back in the early 90th I saw constantly ads for courier flights in the newspaper (newspaper where read frequently at that time). Another big thing then where Milk Runs, where you bring some usually illicit goods (not milk, but not drugs either) to some place. I recall that one Lamma dude got arrested with gold at Kathmandu airport.
Or in a similar matter, is there a way to monetize your unused luggage allowance? I am only interested in totally legal options.
