Quick summary of objection filing borrowed from elsewhere...

Delta forces Pinnacle into bankruptcy sooner by not paying them about $35 million that Delta owed them.

Delta offers DIP financing if Pinnacle will agree to insane terms for the loan.

Delta basically rolls a $40+ million debt Pinnacle owes into DIP financing, so that Delta can do everything they can to make sure they get their money, forget the rest of the creditors.

Delta forces Pinnacle to cancel contracts and return aircraft that may be against the best interests of the business.

The rest of the creditors object to all of this because they haven't had a say at all in this bankruptcy case and Delta basically predetermined what Pinnacle must do in bankruptcy.

All of those things seem to be not allowed because a creditor isn't supposed to use DIP financing as a way to coerce the bankrupt company.
