You can't run a DC-9, Convair, 727, 737, ect on 135, they're payload is too high, has to be less than 6,000lbs for 135. You can run both 121 and 125 on demand, IFL ran 125 for years on demand, and now they're 121.

Also it seems like most people assume that most 135 is freight flown single pilot and it's really not. There's a ton of 2 crew A/C in 135. Out of the 45 planes my company has only 10 are single pilot. Also the size of the company doesn't dictate them being 121, it's the type of planes they fly. Though there are some planes that can be run either 121 or 135 generally they will be run 135 in that case as it's less restrictive.

I guess that's a part of 135 I didn't really dive into. Cool, thanks. Unfortunately I'll probably never return to the 135 world, but who's to say I won't either.
