I heard that the company is using way more positive space than they anticipated for this program. What exactly is the etiquette for using it? I live in DFW, which is a Spirit and AA base.

Is it better to try to non-rev on Delta or jumpseat on one of the other options? From what I understand, as long as I do one of the other, I am entitled to the positive space on the next flight if I can't get on.
