Hi, I`ve done a search for the following but have not come up with any answers.

I have read a long while ago that there are some airline/Private companies that are willing to use people and have them deliver a various objects to other countries. Apparently, the reason why they prefer to use people instead of delivery companies as it is often cheaper and faster. As a return for having these people deliver objects, their airfare is often severly discounted.

Can anyone possible give me information about this?

I'm fairly flexible and am looking for cheaper ways to fly to and from North America (YUL-Montreal) to Europe.

If any one could help, I would greatly appreciate it!
