OK.. I know I'm being very bad here.. but I think I'm about to do this.

Here's what I'm doing. I'm flying AAA-HUB-BBB on a Friday. Now I originally bought this as a RT.. so I got a great weekend fare. But my business plans changed, and instead of flying back to AAA (completing the RT on Sunday), I'm need to stay at HUB. So, I'm going to get on the plane and just not get on the HUB-BBB portion of the flight.

Is this bad?

Note I did not mention the airline. I don't want RPU's all over me.. although it is not on DL.
