Frontier Airlines has a schedule that is in absolute chaos. Today, they announced a flight would be delayed by several hours, and then backed up the departure time by 30 minutes, and then another 30 minutes with only 5 minutes warning.
They did not offer a refund to those who missed the flight, due to their reliance on the intermediate (changed) flight time, nor a reasonable accommodation. "You missed your flight."
Clearly this is a company on the verge of bankruptcy. Nobody in their right mind should buy the dip.
