Narrative:
While on downwind, approximately 14 DME north of aml, we were told to turn to heading 270 degrees, which put us on a base leg. Both the first officer and I set our heading bugs to 270 degrees and the first officer read back the clearance. No other instructions were issued until the controller called traffic ahead of us. We did not see traffic visually. We then had a TCASII TA. The controller then cleared us for a visual to runway 19L. I asked the first officer to confirm runway 19L as we had flown through the runway 19L localizer and made a normal approach and landing to runway 19L and taxied to the gate.

Title: A TCASII TA AND CTLR ADVISORY FOR A CREW ON VECTORS FOR APCH ARE RESOLVED BY A CLRNC FOR A VISUAL APCH TO A RWY THAT WAS UNEXPECTED.
Narrative: WHILE ON DOWNWIND, APPROX 14 DME N OF AML, WE WERE TOLD TO TURN TO HDG 270 DEGS, WHICH PUT US ON A BASE LEG. BOTH THE FO AND I SET OUR HDG BUGS TO 270 DEGS AND THE FO READ BACK THE CLRNC. NO OTHER INSTRUCTIONS WERE ISSUED UNTIL THE CTLR CALLED TFC AHEAD OF US. WE DID NOT SEE TFC VISUALLY. WE THEN HAD A TCASII TA. THE CTLR THEN CLRED US FOR A VISUAL TO RWY 19L. I ASKED THE FO TO CONFIRM RWY 19L AS WE HAD FLOWN THROUGH THE RWY 19L LOC AND MADE A NORMAL APCH AND LNDG TO RWY 19L AND TAXIED TO THE GATE.
