On the issue of commuting home via positive space jump seats: most guys used them to go home unless they lived in a difficult to get to place. No reason not to use them. You can study at home or in an airplane as easily as in DEN. F9 will not book positive space between DEN - ORD or DEN -MCO.

I used a positive space to visit my brother in PBI. Coming home we diverted to DFW due to Snowmageddon. I got kicked off of my positive space Jumpseat from the Captain because two other pilots were commuting to work. Yep, total bull****. Flight cancelled and it was a moot point. Try not to leave yourself with zero options due to a Captain not understanding the program.
