It will be interesting to see how this story unfolds. Conflicting stories on whether or not a pilot declared an emergency - kind of an important point.
Looking at Flightaware, it appears the flight only took one loop in the holding pattern, for 3-4 minutes, before diverting. PIT airspace was opened 10 minutes after landing.

While jets and planes of all sorts filled the skies over Pittsburgh International Airport last weekend for the comeback of a popular air show, there was one big one that didn’t make it that far.
It was Southwest Flight 3316, which took off from Orlando, Fla., at 1:45 p.m. Sunday bound for Pittsburgh International in Findlay only to end up at the Allegheny County Airport, a general aviation facility typically reserved for Cessnas, Pipers and corporate jets — not Boeing 737s carrying 143 passengers.
