BBB,
Hello mate. I think being a Captain on your worst day is better than being FO on your best day. I would continue to build your PIC time on the CRJ and keep the Airbus option open with your airline - but send your apps out to SWA and JB after building more jet PIC time.
You can always bid FO later after another 1000 PIC on the CRJ. I say stick with the CRJ for now.
Cheers
