Loganair were looking pretty short of Saab 340 drivers last time I was in Scotland ... although I heard that non type rated FO applicants are now getting compulsorily screwed for something like £20Kish in some nasty pay-for-type-rating-plus-line-training scheme.
Don't know if they'd try to fleece type rated applicants the same way, but it can't hurt to ask
You also have the hours for Easyjet TRSS entry and should definitely apply there, it's certainly better than a Saab job although it does seem to take a few months for your application to reach the top of the list for interview ...
