Narrative: Unplanned go-around [we were] on Runway 25 by an A320 who was under my control at the Local Control 1 position. Traffic departing 19 complex under the control of Local Control 2. The A320 advised going around; I immediately looked for traffic off 19's. Traffic was rotating midfield; the departure; P180; was to the left of the A320 on a 175 degree heading. I issued traffic on Lear converging and unkeyed to try to hear what Local Control 2 was instructing his traffic to do. My assistant instructed Local Control 2 to have his aircraft stay low and pass below the A320. I keyed up to tell the A320 what the Lear was going to do but visually; saw the Lear climbing and banking right. I instructed the A320 to turn left and established Visual Separation with Lear Jet. Local Assistant was coordinating with L30 and he told me to turn the A320 to 240 degrees; climbed the A320 to 6;000 confirming still visual separation with Lear Jet. Told the A320 to contact L30; the A320 came back to my frequency asking what runway he can expect. I advised Runway 25L and told to contact departure again. During the time of this situation a Traffic Management Coordinator was the CIC. TMU usually monitors Ground Control to help them anticipate flow times. I don't know if the Traffic Management was monitoring a position. I feel if a regular controller was staffing the CIC position they might have caught the go around earlier. When I advised Local Control 2 the A320 was going around I didn't get an immediate response from him that he heard me. Perhaps a Supervisor/Controller CIC would have yelled louder at him. Also a Supervisor/Controller CIC might have taken more immediate action to have Local Control 2 cancel the take off clearance of another A320 who was departing behind the Lear with visual separation.


Second narrative: I was working Local Control 2 during a slow session. I was issuing takeoff clearances to aircraft departing Runway 19L. I issued a take off clearance to a Lear 60 Runway 19L. I gave a subsequent takeoff clearance to an A320 using visual separation from the LR60 ahead of him. After giving both clearances; I heard the Assistant Local Control 1 Controller say that they had a go-around off Runway 25L. I saw the go-around traffic about midfield Runway 25L. I immediately called the traffic to the LR60 who was about 3/4's of the way down Runway 19L and airborne and requested that he 'stay low' or 'go low.' The pilot of the Lear immediately reported the traffic in sight and started to climb at a remarkable rate. I told the Lear to maintain Visual Separation on the traffic when I noticed the Airbus start to begin a left turn. I told the Lear that the airbus was in a left turn now below him and to his left. I then instructed the Lear to contact Departure. With the LR60 now approximately 1.5 miles south of the airport with the go-around approximately 0.5 miles in trail and lower; I issued traffic to the subsequent departure off Runway 19L. The departure reported the traffic in sight; I told him to maintain visual separation with the traffic and to let the Departure Controller know that he had him in sight. I then told the A320 to contact Departure. I don't really know if there is a solution to this issue. The late go-around from the other A320 certainly didn't help the situation.


Synopsis: LAS Controllers described a developing conflict involving a go-around on Runway 25L and departure from the Runway 19 complex. The reporter indicated that a more experienced CIC may have completed the need internal coordination more quickly.
