It has less to do with your time and more to do with where you are coming from. Regionals have historically been leary of ex or furloughed mainline pilots because they assume, probably correctly, that...
1. He doesn't really want to be there.
2. He will leave as soon as he can.
3. He will spread hate and discontent

With that said if you are corporate/135 type it seems that your times would be just fine in the current hiring climate...they probably just have a lot of applicants.

Regionals will also try to consider your personal situation...some would be more inclined to hire an older experienced pilot who is looking for a permanent home. My company has a wide variety of ex fire, bush, night freight guys who are planning on staying.

Regionals tend to be realistic...they know that many of their new-hires will not stay forever, but they want to at least get their money's worth out of you. If they think you will stay for a few years and upgrade they will probably be happy with that.

While the regional business model actually works better with moderate turnover (they want most of the pilots low on the longevity scale) I don't think any of them are smart enough to try to pick guys who will stick around long enough, but not TOO long. I think they mainly just look for red flags that you might bail quickly.

In your case you probably qualify for DAL and other majors, so that might possibly be a factor but I kind of doubt.

Do you have any internal recs? If not, that is the most likely reason they haven't called. Airlines hire mostly on the "family and friends" program.
