I was hoping that somebody could elaborate a little on the per diem write off deal.

I have a credit card that I don't use at all, that I was considering using for my meals/snacks/beverages (non-alcoholic) that I purchase while on the road. This way I would have a paper record of it and can easily see an itemized listing of these expenses, as well as a monthly report. (I would save my receipts too)

Now my question is...I receive $22 / day per diem, everyday.

Would I need to find out what the per diem rate in the city im in is, then keep track of that as i travel all over?...This seems extremely tedious, especially for you regional guys.

Thanks in advance. I understand that asking an aviation CPA would yield more information, however im trying to just get an idea of how it works.
