Narrative:

Departed bos, clearance was for wylyy 3, but we flew logan 2 SID. Departure asked which SID we were following. Only then did we notice we were cleared on wylyy SID. Complacency played a part in this incident. Both crew members are familiar with boston but had not been there in a couple of months since the wylyy 3 was issued. Previously, the only SID was the logan 2 SID. If we had spent more time looking at pre departure clearance from ACARS this wouldn't have occurred. It would also help if the assigned SID was mentioned next to the cleared route on the pre departure clearance, not buried in the text on the last page. Fatigue also played a part since every morning of the trip involved an XA00 wake-up. The incident leg was the second leg of the morning.

Title: A B737-300 FLC FOLLOWS THE WRONG SID WHEN DEPARTING BOS, MA.

Narrative: DEPARTED BOS, CLRNC WAS FOR WYLYY 3, BUT WE FLEW LOGAN 2 SID. DEP ASKED WHICH SID WE WERE FOLLOWING. ONLY THEN DID WE NOTICE WE WERE CLRED ON WYLYY SID. COMPLACENCY PLAYED A PART IN THIS INCIDENT. BOTH CREW MEMBERS ARE FAMILIAR WITH BOSTON BUT HAD NOT BEEN THERE IN A COUPLE OF MONTHS SINCE THE WYLYY 3 WAS ISSUED. PREVIOUSLY, THE ONLY SID WAS THE LOGAN 2 SID. IF WE HAD SPENT MORE TIME LOOKING AT PDC FROM ACARS THIS WOULDN'T HAVE OCCURRED. IT WOULD ALSO HELP IF THE ASSIGNED SID WAS MENTIONED NEXT TO THE CLRED RTE ON THE PDC, NOT BURIED IN THE TEXT ON THE LAST PAGE. FATIGUE ALSO PLAYED A PART SINCE EVERY MORNING OF THE TRIP INVOLVED AN XA00 WAKE-UP. THE INCIDENT LEG WAS THE SECOND LEG OF THE MORNING.
