Narrative:

We departed out of lax on the LAXX5 SID. Just as we were about to make our left turn to 220 degrees; ATC turned us to a 200 degree heading. A few moments later ATC cleared us direct to pevee. I informed ATC that we were on the LAXX5 departure which they responded 'wrong.' I immediately looked at our pre departure clearance and saw the revised segment which had us on the HOLTZ9 SID. Both the captain and I failed to see the revision. I scrambled to get pevee in the computer while ATC gave us an initial 160 degree heading. Within 20 seconds we were direct to pevee and continuing on the holtz SID. I do not believe that at any time we had a major deviation off the departure since ATC was giving us headings. Worst case; we were possibly a bit slow turning to pevee. We both agreed that we needed to pay more attention to the pre departure clearance.supplemental information from acn 785878: on climbout; we were given a heading of 200 degrees then cleared dirct pevee-holtz SID. We stated that we were on the LAXX5 and departure said no; we were on the holtz. We referred to the holtz SID; went direct pevee and were on our way. There were no further comments from socal or center. Contributing factors: one too many passenger aboard a full flight; needing return of jetway; much confusion and arguments about who should be deplaned. I remember asking first officer if we had a clearance; but cannot recall if I inquired about any revised segments. I don't think I actually looked at the clearance. Conclusion: don't let boarding chaos interfere with normal cockpit duties.

Title: A319 FLT CREW FAILS TO NOTE THE REVISED SEGMENT ON THEIR PDC AND ATTEMPTS TO FLY WRONG SID PROCEDURE.

Narrative: WE DEPARTED OUT OF LAX ON THE LAXX5 SID. JUST AS WE WERE ABOUT TO MAKE OUR LEFT TURN TO 220 DEGS; ATC TURNED US TO A 200 DEG HEADING. A FEW MOMENTS LATER ATC CLEARED US DIRECT TO PEVEE. I INFORMED ATC THAT WE WERE ON THE LAXX5 DEPARTURE WHICH THEY RESPONDED 'WRONG.' I IMMEDIATELY LOOKED AT OUR PDC AND SAW THE REVISED SEGMENT WHICH HAD US ON THE HOLTZ9 SID. BOTH THE CAPTAIN AND I FAILED TO SEE THE REVISION. I SCRAMBLED TO GET PEVEE IN THE COMPUTER WHILE ATC GAVE US AN INITIAL 160 DEGREE HEADING. WITHIN 20 SECONDS WE WERE DIRECT TO PEVEE AND CONTINUING ON THE HOLTZ SID. I DO NOT BELIEVE THAT AT ANY TIME WE HAD A MAJOR DEVIATION OFF THE DEPARTURE SINCE ATC WAS GIVING US HEADINGS. WORST CASE; WE WERE POSSIBLY A BIT SLOW TURNING TO PEVEE. WE BOTH AGREED THAT WE NEEDED TO PAY MORE ATTENTION TO THE PDC.SUPPLEMENTAL INFO FROM ACN 785878: ON CLIMBOUT; WE WERE GIVEN A HEADING OF 200 DEGS THEN CLEARED DIRCT PEVEE-HOLTZ SID. WE STATED THAT WE WERE ON THE LAXX5 AND DEP SAID NO; WE WERE ON THE HOLTZ. WE REFERRED TO THE HOLTZ SID; WENT DIRECT PEVEE AND WERE ON OUR WAY. THERE WERE NO FURTHER COMMENTS FROM SOCAL OR CENTER. CONTRIBUTING FACTORS: ONE TOO MANY PAX ABOARD A FULL FLIGHT; NEEDING RETURN OF JETWAY; MUCH CONFUSION AND ARGUMENTS ABOUT WHO SHOULD BE DEPLANED. I REMEMBER ASKING FO IF WE HAD A CLEARANCE; BUT CANNOT RECALL IF I INQUIRED ABOUT ANY REVISED SEGMENTS. I DON'T THINK I ACTUALLY LOOKED AT THE CLEARANCE. CONCLUSION: DON'T LET BOARDING CHAOS INTERFERE WITH NORMAL COCKPIT DUTIES.
