Cheaper prices
 

I once heard of some low-fare ticket offers if travelling with no luggage...Is that true?
If so, is there any www-site where could I get more informations?
Thanks for clueing me in...

Maybe you are thinking of air courier travel? When you let a company use your luggage and only have your carry-on? I don't know much about it, nor have I heard anyone say anything about it so I don't know if it works. Maybe someone else here has some experience?
There is a site you can check out: http://www.courier.org

That'is, thanks a lot!
I get a trip on that site and I found it quite interesting even though there are few infos on flight availability.
I'll keep on trying and searching: any other tip is welcome
