I've been amazed at the weekday Aircraft Movements numbers during December and January. Even though it may show no services, there has been private aircraft flying so it is not as blank as it made out to be on movement page.
Am I currently concerned about lack of Saturday service during Winter. No I am not, this is mainly down to Covid causing a distinct lack of travel demand.
Do I see this Saturday hiatus lasting long. No. Traffic will be back on a weekend as people start moving about more freely.
