The jumpseat denials work in the other direction as well. I spent the night in IAD a couple years back trying to get home when a scab denied me a jumpseat on my commute. I was not happy say the least. The point is politicizing the jumpseat does affect others at times.

I am curious though if any of you keyboard warriors commute, do you take other flights if a scab is the Captain? I actually base my commute on the list when I can and avoid if at all possible.
