A B737-300 CREW; AFTER BEING CLRED INTO POS AT OMA; WERE XING THE HOLD LINE; WHEN TWR ISSUED A HOLD SHORT CLRNC; SPAWNING A TWR ISSUED GAR TO LNDG TFC.

Narrative

WHILE TAXIING FOR TKOF ON RWY 14R; TWR INSTRUCTED US TO 'HOLD SHORT OF RWY 14R.' WE ACKNOWLEDGED 'COMPANY NUMBER; HOLD SHORT RWY 14R.' AS AN ACR B737 WAS XING OUR NOSE; LNDG ON RWY 14R; WE HEARD 'COMPANY NUMBER; TAXI ONTO POS AND HOLD RWY 14R.' WE ACKNOWLEDGED 'COMPANY NUMBER; ON TO POS AND HOLD RWY 14R.' WE FINISHED THE PRE TKOF CHKLIST; CHKED FINAL AND NOTICED A JET AT ABOUT 4 TO 5 MI. THIS SEEMS ABOUT THE RIGHT SPACING FOR US TO BE ABLE TO TAKE OFF AFTER ACR Y CLRS THE RWY. AS WE GET THE FRONT 1/3 - 1/2 OF THE JET OVER THE HOLD SHORT LINE; WE HEARD 'COMPANY NUMBER; HOLD SHORT OF RWY 14R.' WE ACKNOWLEDGED 'COMPANY NUMBER; HOLD SHORT RWY 14R.' TWR THEN SAID 'COMPANY NUMBER; ARE YOU PAST THE HOLD SHORT LINE?' WE SAID 'AFFIRMATIVE.' THEY SENT THE RJ AROUND THEN CLRED US FOR TKOF. ON CTR FREQ; WE GOT A PHONE NUMBER TO CALL TWR. THE CAPT CALLED FROM DEST AND DISCUSSED THE SIT WITH OMA TWR. APPARENTLY; TWR DID HEAR US READ BACK THE 'ON TO HOLD' INSTRUCTIONS; BUT DID NOT RESPOND TO CORRECT IT. TO AVOID/CORRECT THE SIT IN THE FUTURE; I NEED TO LISTEN CLOSER TO SPECIFIC CALL SIGNS AND ANALYZE WHETHER THE INSTRUCTIONS MAKE SENSE FOR US. WHEN ANY DOUBT EXISTS -- ASK! ONE ILLUSION THAT MAY HAVE CONTRIBUTED WAS THE RJ LOOKING FARTHER OUT ON FINAL DUE TO ITS SMALLER SIZE.
