Prop planes are always "more interesting."
SkyWest/Delta Connection flys the Embraer 120 twin turbo prop. It is a great aircraft. That is the usual aircraft used between Pocatello and Salt Lake City.
I checked my ticket. The aircraft is a Beechcraft 1900D. It seats 19 passengers. It's a turbo-prop. Not much different from the EMB120 except seating is a single seat on each side of the aisle. 3 seats in the back row.
