Anyone flying Delta from Laguardia to points south knows the frustration that is Gate 5A. It’s reserved for Comair–excuse me, Delta Connection—flights, which means it’s pretty much the neglected stepchild of the Delta Terminal. I’m flying to Greenville, South Carolina today, which means that, barring a miracle of mercy, I will once again pass through this dreaded portal. The upside: I ALWAYS run into people that I haven’t seen in forever or didn’t even know lived in New York or couldn’t imagine flying on tiny commuter planes. People like USC grad and former NY Knick (tear) Renaldo Balkman.
