Thanks. This is what I was looking for. I know with the airlines per diem can only be claimed from the time spent away form the assigned domicile, regardless of where the pilot actually lives.
This one is a little different though because I am not technically assigned a domicile and I don't live where I work.

I have a mortgage so I itemize my taxes. Should be a nice chunk of change coming back. 80% of the allowed daily rate I think.
