Up to this point Delta has returned 100% of the saabs that have come due to the leasor.... so with that track record I wouldn't say it's a stretch to say they're going to park them all. I'm not happy about it but it looks like Mesaba will be a 600 pilot airline in two years.. based on what Delta has done to Comair I guess they just HATE wholly owned regionals?
As for recall... probably not for a long while.
