In my opinion from discussions with informed sources, "Project Minnow" did not proceed (where David Bronner and Dave Siegel tried to buy all or part of United with RSA funding) due to ego's, primarily that of Glenn Tilton and more importantly Jake Brace.
Furthermore, I understand Doug Parker wants to be a survivor, which makes a deal with United less likely because costs cannot be easily cut with the Chicago-based company now out of its formal reorganization.
Airline consultant Darryl Jenkins who is widely respected throughout the country in airline "executive suites" is convinced that Mr. Parker wants to build the nation's largest airline -- through mergers -- and that the union of US Airway and America West was just the first step. "He definitely wants to make himself bigger," he said of Mr. Parker. Mr. Parker did the US Airways deal because "he wanted to be ahead of the power curve. He has always made it clear this is what he wants," according to the Post-Gazette.
I believe this too and because Parker believes bankrupt airlines are "able to drastically reduce costs by giving unneeded airplanes back to lenders or renegotiating labor contracts -- making either company more attractive to potential partners,", which again the Post-Gazzete recognized.
In my opinion, the leading candidate is Northwest for another corporate transaction although there are certainly more possibilities.
