I was told by an Afflac (SP) representative that their disability insurance will cover you if you cannot perform YOUR job. I specifically asked in respect to the pilot job and loss of medical.
The fine print, the small amount that I read, said that as long as any other job you were working didn't pay you more than 80% (or something like that) of what you were making, you would still receive benefits. One caveat, I have not seen the actual terms of coverage, only what was written in the brouchure.
Not sure if he was being a "salesman" or what, but it may be worth a call to them. I do not have the coverage.
