Hello everyone!
I am having a very hard time getting a straight definition of what Part 121, 125 and 135 are. That is, how can I categorize an airline in what part?
Up to this point I have:
Part 121: Scheduled airlines
Part 125: Airlines with 20 or more passengers
Part 135: On demand
Now my question is: a charter airline that flies 737s, what part would it be? 121 and 125? Is a charter airline considered "scheduled" or "on demand"?
Thank you for any help, as I have read through the CFRs, but the more I read the more confused I get...
