The Daily archive and Route map only show what Wizz Air's official All You Can Fly PDF lists for that date — a once-a-day published roster of intended routes, not a live booking check. The PDF can list a route that isn't actually bookable, or leave one out that is.
Insights and Forecast are built from that same archived PDF data — patterns and a model extrapolation, so they carry the same limitation.
The Live tracker is different: it's using real data. It's the most accurate page for a trip you'd plan, because it reflects real, current availability rather than the PDF roster.
The Planner searches routes from the same PDF roster as the archive, to help sketch an itinerary — check a route on Live before counting on it.
