Distraction; Communication Breakdown
Deviation / Discrepancy - Procedural Landing Without Clearance
General None Reported / Taken
Environment - Non Weather Related; Human Factors
While we were instructed to join the Runway XXC localizer ZZZ; Approach Controller handed us over to Tower Frequency. As soon as we joined the localizer; flying conditions started to deteriorate and became turbulent. Airspeed was fluctuating at 1;400 feet AGL. As a result of this; I had started to get focused on stable approach criteria; and work load gradually increased for both pilots. Over emphasis on stable approach criteria caused a distraction and both PF and PM forgot to obtain the landing clearance. Aircraft landed without any further incidents exited the runway and hold short of XXL. Since we did not hear anything from the Tower; both pilots became aware of the event and switched to Tower Frequency. Flight was completed without further incidents.Tunnel vision on stable approach parameters and Airspeed variations caused distraction. Since COVID-19 breakout; I was not flying as frequently as before. I believe this was factored into this incident.Give some extra time to double check all the required tasks are completed. As we are not flying as frequently as before; configure the aircraft early and passing 500 feet AGL; both pilots verbally verify one last time 'Cleared to Land.'
Air Carrier First Officer reported landing without a clearance and stated lack of flying was a contributing factor.
