I don't know about that. JI successfully managed to double dip on their collateral. For example, JI promised aircraft parts to Wexford at discounted prices but quietly sold them to the highest bidder. This bothered Wexford who complained to the BK court. If I understand the USAir loan, in order to secure it, JI used slots into Reagan and LGA as collateral if they default or fail to get into the air by a certain date. I remember reading that these slots were also promised to Wexford but I don't trust my long term memory on that one. As for the Wexford loan, WRAL reported a while back that they burned through 10 Mil of it.
I don't have links but I believe you can pull the stories from the N&O website.
