The L.A. Times has a great travel checklist online. It gives a "to do" list from one year before your trip up to two days before your trip. I cut and pasted the list into Word. Then I highlight the items as I go along. If you cut and paste into Word you can also edit out or edit in items as you see fit.
You can click on "single page" at the bottom of the article so you can get the whole list on one page.
