An actual FACT regarding this rumor is that Mesa has put forth a motion to the BK court to get approval to reup the letter's of credit that keep the operation going. Yes, there is a bank actually willing to renew the LoC's, but MAG must first get the blessing of the court to proceed.
As of now the court has yet to set a date for objections and the actual motion hearing, but since MAG filed the motion under emergancy status they are wanting to make it a priority.
Mesa probably will most likely get the approval and continue with renewed LoC's, the only problem that might be present goes back to the start of BK when JO said the company had enough funding to get through BK. If that was in an actual court document it would be considered truthful and under oath, so it will be intresting to see if the judge corroletes MAGs request to the above statement. If anything, it will probably bring a lot more scrutiny from the court and creditors.
