Narrative:

Midday jfk operations at sna. Lots of light aircraft traffic and airliner traffic for runways 19L&right. Runway 19L used for light aircraft, runway 19R for airliners. While holding on taxiway a short of taxiway left, tower told us to turn the corner and hold short of runway 19L. First officer acknowledged the call from tower and confirmed the 'hold short of runway 19L.' I, however, was thinking runway 19R. We proceeded on taxiway left toward runway 19L, but since I was thinking runway 19R, I crossed the hold short line for runway 19L. The first officer rightly called for the 'hold short' to me, and I was still thinking/confirming (erroneously) to hold short of runway 19R. The first officer, recognizing that we weren't actually stopping, said 'stop.' at that point, I quickly applied the brakes and stopped the aircraft about 20 ft beyond the hold short line. A light aircraft (a C172, I think) on final went around, seeing that we had crossed the hold short line. Tower then cleared us to 'position and hold' on runway 19R. Lessons learned: 1) confirm with the first officer the actual taxi/hold short instructions. 2) check final approach corridor for traffic. 3) call out simple commands like 'stop now' that don't require further thought.

Narrative: MIDDAY JFK OPS AT SNA. LOTS OF LIGHT ACFT TFC AND AIRLINER TFC FOR RWYS 19L&R. RWY 19L USED FOR LIGHT ACFT, RWY 19R FOR AIRLINERS. WHILE HOLDING ON TXWY A SHORT OF TXWY L, TWR TOLD US TO TURN THE CORNER AND HOLD SHORT OF RWY 19L. FO ACKNOWLEDGED THE CALL FROM TWR AND CONFIRMED THE 'HOLD SHORT OF RWY 19L.' I, HOWEVER, WAS THINKING RWY 19R. WE PROCEEDED ON TXWY L TOWARD RWY 19L, BUT SINCE I WAS THINKING RWY 19R, I CROSSED THE HOLD SHORT LINE FOR RWY 19L. THE FO RIGHTLY CALLED FOR THE 'HOLD SHORT' TO ME, AND I WAS STILL THINKING/CONFIRMING (ERRONEOUSLY) TO HOLD SHORT OF RWY 19R. THE FO, RECOGNIZING THAT WE WEREN'T ACTUALLY STOPPING, SAID 'STOP.' AT THAT POINT, I QUICKLY APPLIED THE BRAKES AND STOPPED THE ACFT ABOUT 20 FT BEYOND THE HOLD SHORT LINE. A LIGHT ACFT (A C172, I THINK) ON FINAL WENT AROUND, SEEING THAT WE HAD CROSSED THE HOLD SHORT LINE. TWR THEN CLRED US TO 'POS AND HOLD' ON RWY 19R. LESSONS LEARNED: 1) CONFIRM WITH THE FO THE ACTUAL TAXI/HOLD SHORT INSTRUCTIONS. 2) CHK FINAL APCH CORRIDOR FOR TFC. 3) CALL OUT SIMPLE COMMANDS LIKE 'STOP NOW' THAT DON'T REQUIRE FURTHER THOUGHT.
