Is this a bug? flightaware.com/live/flight/AAL530

Looked at the PIT enroute and to my surprise a 777, rarely see heavies here or AA for that matter. Glitch of some sort I’m guessing but don’t know how it could happen.

Looks like they were going to divert to PIT then the weather got better at JFK.

Notice how much circling was done near JFK.
