Narrative:

My aircraft was cleared for visual approach to den runway 26R. Traffic was pointed out to be company for the left runway. Visual contact was established and we were told to maintain visual separation which we acknowledged. Note: company traffic was same type aircraft (light transport aircraft). Also note, aircraft for both runway 26L and 26R are on separate control frequencys. In maintaining visual contact with company, we noticed him continue through final for the parallel runway and take what appeared to be evasive action to the right which placed him behind us and out of view. We asked the controller to verify our clearance to runway 26R and he did. He said company flew through final but had us in sight. The landing was uneventful. In conversation with the captain of company flight in question, he said the controller did not issue a turn to final on his expected runway nor did he receive us as a traffic call. A contributing factor to this situation is 2 separate controllers on separate frequencys working extremely close aircraft to parallel runways.

Title: ATC CTLR ALLEGEDLY FAILED TO TURN AIR CARRIER LTT ACFT ON TO PARALLEL RWY FINAL OR POINT OUT OTHER ACFT AS TFC.

Narrative: MY ACFT WAS CLRED FOR VISUAL APCH TO DEN RWY 26R. TFC WAS POINTED OUT TO BE COMPANY FOR THE L RWY. VISUAL CONTACT WAS ESTABLISHED AND WE WERE TOLD TO MAINTAIN VISUAL SEPARATION WHICH WE ACKNOWLEDGED. NOTE: COMPANY TFC WAS SAME TYPE ACFT (LTT ACFT). ALSO NOTE, ACFT FOR BOTH RWY 26L AND 26R ARE ON SEPARATE CTL FREQS. IN MAINTAINING VISUAL CONTACT WITH COMPANY, WE NOTICED HIM CONTINUE THROUGH FINAL FOR THE PARALLEL RWY AND TAKE WHAT APPEARED TO BE EVASIVE ACTION TO THE R WHICH PLACED HIM BEHIND US AND OUT OF VIEW. WE ASKED THE CTLR TO VERIFY OUR CLRNC TO RWY 26R AND HE DID. HE SAID COMPANY FLEW THROUGH FINAL BUT HAD US IN SIGHT. THE LNDG WAS UNEVENTFUL. IN CONVERSATION WITH THE CAPT OF COMPANY FLT IN QUESTION, HE SAID THE CTLR DID NOT ISSUE A TURN TO FINAL ON HIS EXPECTED RWY NOR DID HE RECEIVE US AS A TFC CALL. A CONTRIBUTING FACTOR TO THIS SITUATION IS 2 SEPARATE CTLRS ON SEPARATE FREQS WORKING EXTREMELY CLOSE ACFT TO PARALLEL RWYS.
