If you drop to 0 hours in a month, do you owe the company for your benefits? If so, is there a minimum to not owe?

Can you decline your benefits at Spirit if you get them from another place?

Noisecanceller, go try that and see what you find. I searched Drop to Zero Spirit and it gives ~30 threads, most of which are not even on the Spirit forum. The ones on the Spirit forum are mostly pilots saying Spirit has Drop to Zero, but no details. At least going forward, someone who uses search can find this answer in a consolidated thread.
