sat on the tarmac for 4.5 hours with no explanation, climate control, honesty about the timeline or the situation, or even letting anyone off. The crew was passive-aggressive and sneaky, trying to skirt legal time limits requiring financial restitution for passengers, pretending the "flight had started" even though they didn't budge for another 40 minutes.
