Narrative:

While holding short of runway 8 on taxiway A1, air carrier P xx ab received tower transmission to position and hold runway 8. (All 3 crew members heard the transmission.) the first officer read back the clearance 'air carrier P xx ab position and hold'. This readback was not challenged, however while taking position (approximately 90 degree to line up) tower questioned us as to our presence on the active runway. Understanding to have been cleared into position, the tower controller informed us that the clearance was for commuter X ab. We were instructed to taxi clear of the active while commuter X ab was cleared for takeoff. (They had been holding short of a taxiway further down the runway.) they departed, we taxied back to the hold short line, and commuter X ab landed. We were then reclred into position. Both tower controller and crew members acknowledge a miscom due to similar call signs, however we maintain that it was our aircraft which was cleared into position.
