Latest news, Sep 4, 2026: Ocean-crossing forecasts now apply great-circle math to any long flight segments that have sparse route data, rather than drawing naively Mercator-straight lines. This should improve forecast quality for these flights. Also, I've added Austrian Airlines to the carrier list. 🇦🇹
