If I've got access to a (relatively) inexpensive aircraft (C172, PA28), and I have the means to just fly myself to 500 or 750 hours, then get on with a low-time job that I'd prefer over instructing (say, SIC at Boutique, Great Lakes, AMF), is that a viable path?

After a few years, would I have a decent shot at getting to, say, an LCC (Frontier, Spirit, Allegiant)?

I know the typical path is CFI to regional, so I'd really appreciate insight into whether a Part 135 to LCC path is at all viable. Does HR look down on folks who just flew long cross countries on their own to build time?

Thanks!
