>>However, if the DAL guy is "jumpseating" on a less than full flight (riding in the back) you may be able to convince him to nonrev so that you can "jumpseat", riding in the back. "
This is exactly what I said, although I must not have conveyed it well. The key is where you put your quotes. As a DAL guy, you can let an off-line jumper take the "Jumpseat," that is, he is listed on the paperwork as the jumper, although he must, of course, sit in the back. The DAL guy, who used to be "on the jumpseat," as listed on the paperwork, now "gives that up," and becomes a non-rev. This is what I have done numerous times, although it takes a receptive gate agent, also. Of course, this all assumes adequate room in the cabin, but then so does the subject of this thread, i.e. taking more guys in the cabin.
We're saying the same thing.
