CAPT OF AN LGT USED THE WRONG TXWY DURING TAXI FOR TKOF CAUSING THE ACFT TO HOLD UNDER THE ACTIVE RWY OVER-FLY ZONE.

Narrative

ARRIVED AT ACFT WAS LOADED AND PUSHED BACK APPROX 35 MINS LATE. THIS LAUNCH INVOLVES APPROX 125 ACFT IN A 90 MIN WINDOW. THERE IS RAMP CTL FREQ; A FLT CTL FREQ; AND SPLIT GND CTLRS FOR ARPT. WHEN WE CONTACTED THE FIRST GND CTLR I UNDERSTOOD TO EXPECT RWY 36R AND TAXI VIA QUEBEC AND CHARLIE; HOLD SHORT OF RWY 27. (OF COURSE; THE FREQ IS CONGESTED WITH NONSTOP XMISSIONS DUE TO EXTREMELY HEAVY TFC). ALL OF THIS IS NORMAL FOR OUR OP. UPON ENTERING TXWY QUEBEC THE GND CTLR ASKED IF WE WERE ON QUEBEC. I NOTICED THE FO LOOKING AT HIS ARPT DIAGRAM (WE BOTH HAD THE 10-9 PAGE OUT ON OUR CLIPBOARDS) AND I TOLD HIM WE WERE ON QUEBEC. HE ANSWERED GND CTL THAT YES WE WERE ON QUEBEC. GND CTL THEN SAID THEY HAD INSTRUCTED US TO USE ZULU AND CHARLIE. I ASKED THE FO AND HE SAID YES; THAT WAS WHAT HE HAD UNDERSTOOD AND READBACK; BUT WHEN WE TAXIED PAST ZULU AND TURNED ONTO QUEBEC HE THOUGHT HE MUST HAVE BEEN CONFUSED. CTLR STATED WE WERE UNDERLYING THE DEP PATH OF RWY 36R. WE ASKED WHAT HE WANTED US TO DO AND HE SAID JUST CONTINUE HOLDING SHORT OF RWY 27 ON QUEBEC. DURING THIS TIME A STEADY STREAM OF ACFT WERE TAXIING W OF RWY 27 BTWN US AND RWY 36R. AFTER 3 OR 4 ACFT PASSED WE WERE GIVEN CLRNC TO CROSS RWY 27 AND TAXI TO 36R. I HAVE 2 THINGS TO SAY ABOUT THIS: FIRST; IN ACCORDANCE WITH OUR STANDARD OPS WHEN WE FIRST CONTACTED GND CTL AND RECEIVED TAXI INSTRUCTIONS I ONLY REPEATED THE 'HOLD SHORT OF RWY 27' PORTION AFTER THE FO HAD RESPONDED TO THE CTLR. MAYBE WE SHOULD REPEAT THE ENTIRE CLRNC. THAT WAS THE FIRST MISTAKE. WE BOTH KNEW TO HOLD SHORT OF RWY 27 BUT WHAT TXWY TO USE WAS MISUNDERSTOOD. SECOND; WHEN I DID NOT MAKE THE TURN ONTO ZULU (WHICH IS WHERE THE FO THOUGHT WE WERE TO GO) HE SHOULD HAVE QUESTIONED ME OF MY INTENTIONS AND WE COULD HAVE VERIFIED THE CORRECT RTING WITH GND CTL. LONG NIGHTS; BROKEN ACFT; REROUTES; TAILSWAPS; BEHIND SCHEDULE; LOUSY WX; AND EXTREMELY HIGH TFC CONGESTION ALL ADDS UP TO 1 THING: GO SLOW; TAKE YOUR TIME; AND QUESTION ANYTHING YOU DON'T UNDERSTAND OR AGREE WITH IMMEDIATELY!
