Currently the FARs put the task of being rested mainly on the crew member. With 117 the company and pilot share the responsibility equally. With 117 crew members will be required to sign the release every leg stating they are fit for duty. I haven't read the entire reg cover to cover, but from talking with the guys working on it here, it's going to be a mess.

And regarding commuting, if your show is 8pm the company must make sure you got the required time for rest...it's up to you to make use of it. The memo that went out to our pilot group a couple of months back introducing some 117 concepts had a section on commuting. It basically said that while the regs don't prohibit it, that pilots should review their base/seat preference bids and take the new regs into account and bid according. The way the company wrote it got my attention.
