Seems the problem is with the "visual" sites. I get the idea that their delay may be many minutes, or even hours.
Just a little frustrated.
Most of the public flight tracking site are delayed by at least several minutes, due to FAA regulations regarding public distribution of that data. Try flightradar24.com and look at the ADS-B equipped planes…which is an increasing portion of the fleets out there. Those are shown in real time. Yeah, it's not every plane, but it will give you something to enjoy.
