Passengers did have the opportunity to get off the plane due to it still being at the gate and its fourth boarding door remaining open through the delays, Trull said. If the door was closed and the plane was off the gate, then a snack would have been provided “after a period of time,” he said.

The heat could be attributed to it being a “hot day,” but a preconditioned air hose was likely attached to the aircraft and pumping cool air from the jet bridge aboard the plane, Trull said. He did not say if the hose was connected, but confirmed that a piece to hook it up with was available. Contino shared on Twitter Sunday night that the plane’s air source appeared to be off or low because “They turned it OFF to save fuel until people started sobbing and having panic attacks.”
