As 43 said the Saab offers more frequencies and this is very important to the businesses or government traveler who generally purchase the higher or full fares. They want to spend as little time possible out in a regional town and want to be home before dinner is served. Even if getting home earlier by 45mins may cost $100 more they don't care (probably because they're not paying for it)
Just how long can the company compete with older aircraft
well considering they dont compete with anyone on 3/4 of their routes ....
