Narrative:

Air carrier X requested a lower altitude than FL330 because of reported turbulence ahead. I coordinated with 2 slc sectors, and then cleared air carrier X to FL290. On the descent air carrier X may have violated the airspace of a third sector for about 3 mi and about 700 ft. Better sector boundary displays on sector maps and pvd's may have prevented this occurrence.
