as a former pilot, I can tell you that we are really dumb from the perspective of advertising VIP movements. Most of the time, for a pre planned trip, I get notifications of TFR (temporary flight restrictions) related to VIP movement. They never spell out who the VIP is, but when the trips are planned in advance, the notice goes out as soon as that plan is released. could be day of, could be weeks early.
