It costs over a thousand USD to take some ocean liners.
What are alternative ways that are cheaper, and how would one go about it?
(No planes)
For context, I know someone who went from China to California by freight ship in the 1990s by bribing the captain with beer and their cooking skills.
Which ocean? Do you care where you start and/or end your journey? Miami to Barcelona is going to be very different than Long Beach to Shanghai.
