Narrative:

Coming in on the irnmn 1 RNAV arrival into lax; we had a couple of slight wake turbulence encounters. On downwind into lax; we found we were following an A380. I said I was going to keep the glideslope one dot high; landing behind the A380; the captain agreed with that assessment. When cleared for the visual and told to switch to tower at jetsa with traffic and airport in sight. The captain reminded me to keep it a dot high behind the super. I was concentrating on hand flying the approach a dot high; and the captain was closely monitoring my flying. We both forgot to switch over to tower at jetsa and landed still on approach frequency. I didn't realize until we had taxied clear and were holding short of 24L that were not on tower; and still on approach. We quickly switched frequencies to tower and said we were clear of the runway (runway 24R) and holding short 24L. Tower asked us 'what happened?' we replied; 'we got busy on the approach.'I think we both became too engrossed in the approach; and possibility of a wake upset; that we lost our situational awareness on which frequency we were. We should have realized by our lights switch position. We had not been cleared to land; and had not contacted tower.

Title: B737-700 flight crew reported landing without clearance after being distracted by a wake turbulence encounter on arrival into LAX.

Narrative: Coming in on the IRNMN 1 RNAV Arrival into LAX; we had a couple of slight wake turbulence encounters. On downwind into LAX; we found we were following an A380. I said I was going to keep the glideslope one dot high; landing behind the A380; the Captain agreed with that assessment. When cleared for the visual and told to switch to Tower at JETSA with traffic and airport in sight. The Captain reminded me to keep it a dot high behind the Super. I was concentrating on hand flying the approach a dot high; and the Captain was closely monitoring my flying. We both forgot to switch over to Tower at JETSA and landed still on Approach frequency. I didn't realize until we had taxied clear and were holding short of 24L that were not on Tower; and still on Approach. We quickly switched frequencies to Tower and said we were clear of the runway (Runway 24R) and holding short 24L. Tower asked us 'what happened?' We replied; 'We got busy on the approach.'I think we both became too engrossed in the approach; and possibility of a wake upset; that we lost our situational awareness on which frequency we were.
