Relative demand data, meaning the relative share of pax/cargo that want to travel from country A to country B, is based on real-world schedule data. But since those data extracts are fairly expensive, we only do an update every few years. It’s very well possible that the latest developments on the IL-AE routes aren’t reflected in our current dataset.
I have initiatives on the roadmap (location-based demand, custom trips-per-capita) that partially address the issue, but relative demand figures would need an even more sophisticated model that also uses publicly available sources to somehow generate plausible inter-country demand levels.
