Another option is a subcontractor, like ATS or Swissport.

I worked for ATS for nearly five years. While the pay wasn't nearly as high as an airline they were very flexible with my schedule, paid well enough, and I enjoyed working there. When I left, I took what basically amounts to a pay cut to play FO.
