Under the circumstances, better plan for some period of unemployment.
Alternatively you get spend that time at a regional for the pay and benefits.
Upside to the regional route: Additional boxes to check on major app, enhancing your odds of getting called sooner by the legacy of your choice(s). Also *most* regional training programs are more accommodating than *many* majors these days, so it might provide an easier transition into 121. If it takes too long to get a major call you might need the recency, would suck to end up with no calls six months down the road and THEN realize you'll need a regional for the currency.
Downside: Pay during training won't be that much. In the unlikely event that you bust a key training event at a regional, that will set you back on your major app scoring and you'll have some 'splainin to do at a major interview. Also the geography of training and junior domiciles will not likely be convenient for your family (if any), and you'll have to do it all over again at the major.
