You seem to have pretty good quals. The only "weakness" if you can call it that may (or may not) be coming from your 91/135 background. There is nothing wrong with that kind of flying per say, but pilots from that background tend to have less of an active network in the 121 environment.

I'd suggest leveraging your network to a greater and more active degree, and going to job/career fairs. Also make sure you have something "extra" on your resume if you can, like check pilot, safety department, standards, pro stans, etc. as well as some type of volunteer activity. Doesn't have to be a ton.

Update monthly and aggressively pursue the jobs you want. The wave has just started. You should have a pretty good chance at getting multipile calls with the times you have especially if you help yourself.
