Traveling overseas is expensive. Even with the best deals, an international flight costs hundreds of dollars...maybe even thousands if you want the best of luxuries.
If you just want to get there, however, and really don't give a damn about amenities, would you mind being shipped to your destination like cargo? The fee would be minimal...about the same as sending a package through the mail. There'd be no luxuries (bring your own food and drink and whatever else you might need), but you'll get there safely and inexpensively. Would you go for that?
