Don't worry, they will fix the homeschoolers too. They have found a potential loophole by requiring state issued IDs for children under 18 to fly. In order to get one of those state issued IDs, guess what? Proof of enrollment in school. If you don't have a cover group, it is time to call HSLDA.
In NYS a child can get a non-drivers ID. You go to the DMV and go through pretty much the same process as for a permit or license. We did that when we homeschooled.
