Airlines like Loganair are accustomed to the fact that there will be a high turnover of pilots, especially when the job market is good like it is at the moment. The middle aged Scot who lives near a Logan base would be the ideal candidate, however the job market is very buoyant in Scotland as a whole and the numbers of ideal candidates for Loganair are dwindling fast... hence the apparent increase in demand for low hours integrated candidates. They need crews to fill their aircraft and there are not many potential long term employees out there. Instructors are in some cases getting snapped up very quickly by a variety of airlines in Scotland. If they get a couple of years out of you then I am sure Loganair would be satisfied with that!
To answer smith's question... A Saab TR is useful since it gives you sound flying experience in a modern prop enabling you to broaden your horizons for that next move!
