TooSlow,
I agree with a previous post, check out the WIA funding for a type rating. A great way to advance your qualifications and "marketability" when things turn around. And the suggestion to go out and get your dispatchers certificate is a GREAT one. Realitively easy to complete, and my twin brother (a corporate dispatcher) tells me there are ample job opportunites all over the country for dispatchers, both regionally and corporate.
I would caution you, though, not to rely on anything out of your control. A letter of intent with any carrier, or recall rights, DO NOT guarantee future employment. I've been at this a little longer than you, and I've found that you tend to make your own breaks. Don't sit and wait for something that may never happen. Get proactive now.
And I also wouldn't worry about the "what did you do to stay current" question in a future interview. If you have the ability to fly, great, do so. But these are unusual times, and a tactful response ("I first looked at maintaining my currency by flying, but my family is my primary responsibility, and I needed to provide for them first. I still continue to seek employment in aviation, too") will go a long way to show your value system to any recruiter.
Good luck to you. I truly wish you the best. These are difficult times, I know (I, for one, was furloughed from a major airline after 15 years, but now I'm in Phase 2 at JetBlue and couldn't be more excited), but these times will pass, and better times will soon shine upon us all.
