Why is FAAwait’s map different than the one shown on fly.faa.gov?
The FAA uses different logic in displaying their map. They factor all possible delays into each airport’s overall status, under the reasoning that a flight leaving a trouble-free airport to go to one with a problem will be subject to a delay. As a result, on the FAA map airports all tend to be the same color, because a delay at one major airport will be reflected at just about every other airport (since it likely has at least one flight to it). This makes it difficult to use that map to visually see where the true issues are, since an airport may be listed as problematic just because of the destination of a few flights. However, the FAA map is accurate in the sense that a flight originating from any airport is subject to delays driven by its destination. FAAwait only shows delays specific to that particular airport, but keep in mind that those delays may impact departing flights differently than arriving ones (the highest overall delay is shown, regardless of type). And any airport sho
