"Isn't it true a lot of 135 guys fly solo? If so, that seems like a better way for a low time guy to eat it rather than gain knowledge from a captian"

There are no low time guys who fly "solo" IFR 135. You gotta have 1200 hours to meet the mins. Another reason pax airlines shouldn't be hiring 121 F/O's with 300 hours. Heck, you gotta have 1200 just to fly IFR 135, what does that tell ya?

135 freight won't touch low timers cause the FAA says they don't have the experience to do the job safely...and their right.
