I flew LEX-PIT a few months ago on Shuttle America. It was embarrasing. During the flight attendants level off announcement, he mentioned the beverage service. "I only have onboard a few diet Cokes, a coke, two Sprites, some juice and one beer and two wines. I also have little ice." At the time it was quite humorous, but in fact, it is sad that USAirways allows this carrier to fly for them.
Despite the flight attendants announcement, he was dressed to uniform standards and was quite attentive to us. He actually tried to have a conversation with each of us individually. There was less that 20 on board. The flight was fine. The legroom appeard to be more than a Dash 8. But, i would pick a Dash 8 anytime over the Saab.
