When I had to call my car service to let my friend Billy know I was coming home from DFW
I placed a call on the AT&T airphone and heard a pre-recorded message saying if I answered a few survey questions I can get the NEXT call free (that's ONE CALL ONLY.)

So I called, answered the survey and when I
am in an airplane next time I get a free call.

I believe the promotion's good until June 30.
I did not see this anywhere. CATMAN
