The entire system kept crashing requiring lengthy reboots. It was in one of the company emails. Phone tree failures don’t lead to the crewing failures. At least not on the scale that has happened over the last week. We’ve been short handed all summer. Sitting off the gate for 45 minutes isn’t unusual. Neither is one gate agent running gate to gate trying to work multiple flights. While inconvenient, those didn’t lead to meltdowns. While there were many issues leading to this, there was really only two main things that did it. Shortage of non crew staffing was not the proximate cause.
