I was looking into Spirit's bankruptcy(s) and it's really fascinating.

One of the creditors that piloted their exit from the first bankruptcy also provided on $80M out of a $270M line of credit secured by assets Spirit needed to survive (an RCF was backed by their right to take-off and land at LGA amoungst other thinfs)

1 week before the 2nd bankruptcy, Spirit drew against the entirety of that line of credit.

During the 2nd bankruptcy, besides rolling large amounts the debt owed to them from the 1st bankruptcy (so Spirit would need to pay it back before other creditors), they had the proceeds of plane sales go towards... interest payments on their RCF and paying back additional financing from the 2nd bankruptcy.

The creditors leading the 2nd bankruptcy also sold the lease to Spirit's largest hangar on April 2nd, but did a similar thing again: instead of the cash going towards operations, it went to the creditors who'd led both bankruptcies.

Seeing as they refused the government's bailout, I'm guessing this is doomed as well, but interesting stuff for a non-finance person
