Cost to fly w/ Delta Buddy Pass

Can someone kindly give me an idea of the cost for a buddy to travel on a DL buddy pass.
For example:
New York - Florida
NYC - Toronto
NYC-London

I've heard that the cost is not all that favorable and would like to know if I want to travel on such pass (I'm aware of restrictions, such as waiting for days to get on a flight)
Thanks.

Your best resource for this info is the employee who will be supplying the buddy pass.

We are not supposed to answer to this kind of question, you must ask the employee who will provide you the buddy pass.
