You guys are talking about 121, which I know nothing about. But under 135, it isn't an interpretation or a "gray area." Ferry flights are SPECIFICALLY excluded from 135 under 135.1. Thus, if no revenue passengers or cargo are carried, it is a 91 operation.
The call sign thing is interesting. At my present company, and others I have flown for, we used the company callsign whether 91 or 135 (many of our trips are 91 because we are carrying the owner of the aircraft). I am not aware of any restrictions on using the callsign, but I also haven't seen any regulatory references to it either way-- anyone have a link?
