Narrative:

Approach to runway 10-08 at sju, given lower altitude to 1500 ft and intercept localizer runway 10, captain called airport in sight, however we were lined up on some other runway wnw of sju. We were given visual approach clear and descended to 1000 ft. As I recognized the airport I was looking at was not the sju complex, I elected not to descend below 1000 ft and called out to the captain that I did not have the airport in sight as the captain did. The FMC appeared to have 10 split runway in sight. The captain directed me to further almost aligned with the localizer but left of course with the other. Wrong. Runway drift to our left. As I did not have to correct to the south to align on runway 10 at sju, tower called us that the airport was at 1 O'clock 4 mi, I then picked up the complex and continued the approach. Apparently (air carrier Y) 757 landed on the wrong runway wrong airport last week. Captain thought I was familiar with the bogus airport and runway wnw of sju, I wasn't. Tower asked us to call upon arrival, discussion entailed our positioning on final approach, and gave us the heads up to previous (air carrier Y) incident. Event was noted. ATC said there was no report to follow. Lessons were learned by all, bottom line, never assume. Ask lots of questions, speak up as we did in the cockpit if the big picture is not what should be. Have a team effort to confirm and verify as we did before it gets too late.

Title: FLC OF AN LGT LINED UP WITH A SIMILAR HDG RWY AT THE WRONG ARPT.

Narrative: APCH TO RWY 10-08 AT SJU, GIVEN LOWER ALT TO 1500 FT AND INTERCEPT LOC RWY 10, CAPT CALLED ARPT IN SIGHT, HOWEVER WE WERE LINED UP ON SOME OTHER RWY WNW OF SJU. WE WERE GIVEN VISUAL APCH CLR AND DSNDED TO 1000 FT. AS I RECOGNIZED THE ARPT I WAS LOOKING AT WAS NOT THE SJU COMPLEX, I ELECTED NOT TO DSND BELOW 1000 FT AND CALLED OUT TO THE CAPT THAT I DID NOT HAVE THE ARPT IN SIGHT AS THE CAPT DID. THE FMC APPEARED TO HAVE 10 SPLIT RWY IN SIGHT. THE CAPT DIRECTED ME TO FURTHER ALMOST ALIGNED WITH THE LOC BUT L OF COURSE WITH THE OTHER. WRONG. RWY DRIFT TO OUR L. AS I DID NOT HAVE TO CORRECT TO THE S TO ALIGN ON RWY 10 AT SJU, TWR CALLED US THAT THE ARPT WAS AT 1 O'CLOCK 4 MI, I THEN PICKED UP THE COMPLEX AND CONTINUED THE APCH. APPARENTLY (ACR Y) 757 LANDED ON THE WRONG RWY WRONG ARPT LAST WEEK. CAPT THOUGHT I WAS FAMILIAR WITH THE BOGUS ARPT AND RWY WNW OF SJU, I WASN'T. TWR ASKED US TO CALL UPON ARR, DISCUSSION ENTAILED OUR POSITIONING ON FINAL APCH, AND GAVE US THE HEADS UP TO PREVIOUS (ACR Y) INCIDENT. EVENT WAS NOTED. ATC SAID THERE WAS NO RPT TO FOLLOW. LESSONS WERE LEARNED BY ALL, BOTTOM LINE, NEVER ASSUME. ASK LOTS OF QUESTIONS, SPEAK UP AS WE DID IN THE COCKPIT IF THE BIG PICTURE IS NOT WHAT SHOULD BE. HAVE A TEAM EFFORT TO CONFIRM AND VERIFY AS WE DID BEFORE IT GETS TOO LATE.
