Narrative:

Taxi instructions were to taxi to runway 12L via taxiway C. We were told to follow a B757 on taxiway P. After the B757 took position and hold on runway 12L we were told to pull up to #1 spot for takeoff. We both heard to take position and hold and read the clearance back. The clearance was not for us. As we were taxiing for position and were 'clearing left and right' I saw an air carrier jet also taxiing for the runway. He was taxiing on runway 6. We had already slightly crossed the hold short line and stopped. We notified tower we had crossed the hold short line. After the other aircraft departed, we were told to cross runway 12L, turn left and hold short of runway 12L on runway 24. A B767 landed and then a group of fighters landed. We then took off. Our crossing over the hold short line did not affect departures or arrs. We had no affect on traffic flow whatsoever. After departure, the tower asked us to call the tower on arrival at destination. We called back to the tower and I talked to the manager, and he explained the 'position and hold' clearance was not for us. He told me basically to try and be more vigilant in the #1 position and to remain task free when #1. Excellent suggestions. He also stated there should be no further action.

Original NASA ASRS Text

Title: FLC ASSUMES POS AND HOLD CLRNC WAS FOR THEM AS THEY CROSS HOLD SHORT LINE BEFORE STOPPING.

Narrative: TAXI INSTRUCTIONS WERE TO TAXI TO RWY 12L VIA TXWY C. WE WERE TOLD TO FOLLOW A B757 ON TXWY P. AFTER THE B757 TOOK POS AND HOLD ON RWY 12L WE WERE TOLD TO PULL UP TO #1 SPOT FOR TKOF. WE BOTH HEARD TO TAKE POS AND HOLD AND READ THE CLRNC BACK. THE CLRNC WAS NOT FOR US. AS WE WERE TAXIING FOR POS AND WERE 'CLRING L AND R' I SAW AN ACR JET ALSO TAXIING FOR THE RWY. HE WAS TAXIING ON RWY 6. WE HAD ALREADY SLIGHTLY CROSSED THE HOLD SHORT LINE AND STOPPED. WE NOTIFIED TWR WE HAD CROSSED THE HOLD SHORT LINE. AFTER THE OTHER ACFT DEPARTED, WE WERE TOLD TO CROSS RWY 12L, TURN L AND HOLD SHORT OF RWY 12L ON RWY 24. A B767 LANDED AND THEN A GROUP OF FIGHTERS LANDED. WE THEN TOOK OFF. OUR XING OVER THE HOLD SHORT LINE DID NOT AFFECT DEPS OR ARRS. WE HAD NO AFFECT ON TFC FLOW WHATSOEVER. AFTER DEP, THE TWR ASKED US TO CALL THE TWR ON ARR AT DEST. WE CALLED BACK TO THE TWR AND I TALKED TO THE MGR, AND HE EXPLAINED THE 'POS AND HOLD' CLRNC WAS NOT FOR US. HE TOLD ME BASICALLY TO TRY AND BE MORE VIGILANT IN THE #1 POS AND TO REMAIN TASK FREE WHEN #1. EXCELLENT SUGGESTIONS. HE ALSO STATED THERE SHOULD BE NO FURTHER ACTION.
