To echo the other folks on here. I didn't keep a line by line log of my military time (15.5 years). When I started prepping last fall for my transition, I took my Flying History report and made a single line entry in logbook pro for each aircraft I flew in the military. (I made two entries for my C-17 time, one for prior to AC school and one for all time after AC School) All flying I've done since then, I've kept a line by line entry in my electronic logbook. So now, when I use logbook pro to print out totals, etc. It has all my military time included with my line by line entries. For things such as PIC, cross-country, etc. that the military doesn't keep track of, I used my own calculations and estimations and include a page explaining what I did to come up with those totals.

I bought a leather binder and keep up too date printouts of everything and include my explanation sheet and flying history report in there as well and that's what I brought to my regional interviews (PSA & SkyWest). Neither airline had any questions regarding my flight time.
