Often airlines engage in merger rather than collapse. See US Airways (bankrupt) + America West, and later American Airlines (bankrupt) + US Airways.

I think the bankruptcy process does tend to lead toward spectacular failure when the cost of operating is too far above the revenue from operating. Decreasing operations during bankruptcy makes the company less attractive and may not even significantly help the net revenue situation. You really need to be solvent or nearly solvent to have an orderly winding down. That said, wikipedia says they did reduce scheduled flights by 25% in Nov 2025, and I think they reducsd the size of their fleet in a similar time frame, so it could have been that much more confusion and delay.
