Stowaway Travel

Cheapest fares to Hawaii, Iceland, and places in the near East, like Teheran, Istanbul. Also, Italy.?
I have not had much success with the usual search sites, like cheapfares or Orbitz. Can you suggest other means of travel? Any luck with courier service? Hitchhicking on a private jet or yacht? Freighters? (We won't go stowaway!)
Thank you.

After 9-11, the days of cheap and unconventional travel have become more challenging. Gone are the days of the one-way ticket to Bangkok. I believe, however, that bucket shops still exist overseas and you can buy cheap tickets once you are outside of the US. Way back when I used to travel, my favorite series were Lonely Planet and the Rough Guide. (URL's below). Whatever you do, make sure your passport is current and not about to expire! Avoid the hassle! oh, and if you have a student i.d., make sure you check out http://www.statravel.com/ Bon voyage!
