Last night I was working Hawaiian flight 2 into LAX. We were about three hours late (mechanical probs), and when we were approaching the California coast, we heard an Alaska flight declare an emergency for smoke in the cockpit. They dove back to LAX and landed parallel to us - they were on 25R and we were on 24R. We both landed at about 11:45pm local. Does anyone with connections at AS know what happened? They taxiied back to the gate under their own power and didn't seem too much in a hurry.
As we approached the coast we could see the huge brush fire north of the LA basin, and flew through some of its smoke, which was definitely a noticeable smell during descent. Was it possible that was what they smelled?
