Doug,

I started using Compassion Flight etc and changing my 'N-number'. I was
getting questioned so much by ATC, that I figured it wasn't worth it. So,
now I just use my N-number, but if I need 'special attention' I add, "...and
we're an Angel Flight today". Occasionally I also add "...and we have a
really cute girl in the back who can't wait to get home" (or something
similar). FWIW: That works like a charm, from jumping to #1 from #7 at PAO,
to flying the PAO approach with no delay (in IMC) etc. But while getting
handed off on a long XC, I just use my N-number.

So I wonder how often using "Compassion" or "Angel Flight" makes a
practical difference?

Another poster noted that his brain was trained to hear his normal call
sign and had missed "Compassion" more than once. Something to consider...

Perhaps Hilton has the right idea.
