I'm looking forward to a renovation of the Part-135 regulations as well.

In my humble opinion, I think that the use of Part 91 is an 'easy way out' for an operator to put someone on the road way too long at once. I recently flew a trip from Ohio, to Arkansas, to Texas, all in one day in a Caravan. Used all 8 hours of flight, and was on duty around 15 hours. When I got to Texas, I was told, "Hey, the trip home is part 91, doesn't count towards anything, so way don't you just climb back in and come home now?" If I had done that, I would have flown about 16 hours, and been on the road for over 24 hours straight, and it's LEGAL.

I told them to get me a hotel. I believe in rest.
