122.9 is commonly used for air-to-air communications? I thought it was a
designated UNICOM frequency for airports where no other UNICOM frequency was
published. There are specific air-to-air frequencies, right? And 122.9 is
not one of them, right?

I guess that's my point. There are several, if not many, frequencies that
could be used. Unless one is officially designated or at least publicized as
the right one, what are the chances that a collection of pilots flying along
the Chicago lakefront (or around the Class B in general) will just happen to
pick the right one?

122.75 makes more sense to me than 122.9, since the purpose is basically
position reporting between airborne pilots and their planes. There is no
reason why Joe Pilot would choose that frequency above all others (unless
they happen to be reading this thread of discussion).

Someone mentioned that the VFR corridor around New York had a published
frequency. Is it one of the air-to-air freqs or a designated CTAF or ATC
frequency? Who took the initiative to get it published? Was is ATC trying to
offload VFR flight following or a grassroots effort by pilots?

Why did Jim suggest 122.9?

It's commonly used for air-to-air communications, the proper frequency for
that is 122.75.
