I think it´s a very simple doubt but also very important, and i can´t find the answer. If you are flying on a Federal Airway that at some point cross a class B airspace (for example)...do you need authorization or can you keep flying without one?

    $\begingroup$ Ask for Flight Following on your flights, they will more than likely help you out in those situations. $\endgroup$

If you are flying your IFR flight plan which you got clearance for, then you have permission already.
If you are flying VFR you need to ask ATC for clearance.
Class B airspace requires clearance for all traffic and separation is also provided by ATC for all traffic.
