Why was FlightCasters prediction wrong?
Unfortunately, we can’t be right 100% of the time. There are natural sources of error, some more likely than others: • Airline does something weird: Sometimes this is good (rolling up a new plane, giving your flight priority over another). Oftentimes this is bad (no crew, no gate, random cancellation). We aren’t in their heads so we do what we do based on external analysis. Please keep this in mind when you use our service. • Weather or Traffic changes: We use observations and forecasts for both weather and air traffic. We are always evaluating them for quality, but they are not perfect. If the weather clears up or gets nasty outside of the forecast, it will mess with our algorithm. If the FAA changes traffic management patterns on us, that might also cause some error. • Bad data: This should be a rare occurrence thanks to our friends at FlightStats, but sometimes the data comes through messy from the airlines, airports, or the FAA. If that happens, well, it will impact our predictions
