FLC ACR MLG ACFT DEVIATED FROM ASSIGNED CLRNC DUE TO MISREADING THE AMENDED PREDEP CLRNC.

Narrative

THIS WAS A QUICK TURN WITH EVERYTHING QUITE RUSHED AS THE ACFT ARRIVED LATE FOR OUR DEP. I GOT THE CLRNC VIA ACARS AND MENTIONED TO THE CAPT THAT WE NEEDED TO CHK THE ROUTING. IN THE CLB IT WAS QUITE BUSY AND THE FLT ATTENDANT CALLED THE COCKPIT FOR HELP WITH A STUCK SERVING CART. THE CAPT SENT ME BACK; AND WHILE I WAS GONE; ZOA CALLED AND ADVISED US THAT IT LOOKED LIKE WE WERE DIVERGING FROM J-84 AFTER LIN. A CORRECTION WAS GIVEN AND UPON CHKING; WE CONFIRMED THAT THERE WAS A DEV FROM OUR FILED FLT RTE. THE ROUTING IN THE ACARS LOOKED LIKE THIS: -- SFO6 LIN J84 MVA J198 ILC -- SFO6 LIN OAL J58 ./. MCI. I HAD PLUGGED THE STORED FLT PLAN ROUTING INTO THE COMPUTER WHICH WAS THE SECOND LINE OF THE FLT PLAN ON ACARS AND CHKED IT AGAINST OUR COMPUTER FLT PLAN FROM DISPATCH WHICH AGREED. I FEEL THAT THE FORMAT IN THE ACARS CAN BE CONFUSING AND CAN BE MISLEADING. PERHAPS IF THERE IS A DIFFERENCE IN THE FLT PLAN; THE ENTIRE NEW FLT PLAN ROUTING ONLY SHOULD BE SHOWN; JUST LIKE IT WOULD BE GIVEN (READ) BY CLRNC DELIVERY OVER THE CLRNC FREQ. (NO NOT PRINT THE OLD ROUTING NOT TO BE FLOWN.)
