Narrative:
Bos approach vectored air carrier X towards runway 4L. Traffic was pointed out for runway 4R. Air carrier X called traffic in sight and was cleared for visual approach to runway 4L to maintain visual separation from traffic. Air carrier X proceeded toward runway 4L from the west side of runway 4L centerline while traffic approached runway 4R from the east. Air carrier X received landing clearance from bos tower and proceeded to land without incident on runway 4L. Tower noted to air carrier X runway 4R traffic was going around.

Title: B737 CAPT MAKING VISUAL APCH PROC TO BOS RWY 4L WITH PARALLEL TFC ON RWY 4R EXECUTING GAR.
Narrative: BOS APCH VECTORED ACR X TOWARDS RWY 4L. TFC WAS POINTED OUT FOR RWY 4R. ACR X CALLED TFC IN SIGHT AND WAS CLRED FOR VISUAL APCH TO RWY 4L TO MAINTAIN VISUAL SEPARATION FROM TFC. ACR X PROCEEDED TOWARD RWY 4L FROM THE W SIDE OF RWY 4L CTRLINE WHILE TFC APCHED RWY 4R FROM THE E. ACR X RECEIVED LNDG CLRNC FROM BOS TWR AND PROCEEDED TO LAND WITHOUT INCIDENT ON RWY 4L. TWR NOTED TO ACR X RWY 4R TFC WAS GOING AROUND.
