Jim,
Thanks for the link. Interestingly, I found evidence in this article to support the notion that US is not yet a "party-in-interest," despite the similar, but ambiguous, language used by Bethune in his affidavit:
Delta has exclusive rights until Feb. 15 to submit a reorganization plan to the court, and until Apr. 16 to seek acceptance of it. US Airways will be able to work with creditors during this period, but not with the court. If Delta seeks an extension of its exclusivity, as it has done three times so far, US Airways won't be able to oppose the request itself; it will have to find creditors willing to take its position.
In order to file a motion to oppose a time extension, you must be a "party-in-interest" as well. Although, that term is not really defined, I am convinced that the "party-in-interest" in regards to a time extension is the same as, or similar, to the "party-in-interest" in regards to filing a plan after the exclusivity period.
Now, as I stated in other threads, US is certainly aware of this. US simply has not needed to be a "party-of-interest" up to this point. Even if DL does seek a time extension, US can request a creditor to do the dirty work on its behalf and file a motion. But when it comes time to file its own plan, US will need to take certain actions to become a party-in-interest... the most likely scenario is US purchasing a
small claim to become an actual unsecured creditor. Of course, US will probably have to pay a multiple above the actual value of the claim, as US is in a lower bargaining position. If US takes this route, it will likely happen days before February 1st.
