* The flight was technically a Republic Airlines flight subcontracting for United Airlines.
* Almost none of the staff involved worked directly for United Airlines; they are subcontractors required to wear United Airlines' branded uniforms.
* Republic Airlines is bankrupt, and none of the parties involved in the lawsuit has attempted to shift blame to them.
* United Airlines is capable of bypassing union wage requirements by subcontracting through partner airlines, so they have a vested interest in keeping Republic afloat through its bankruptcy (and therefore, discreetly accepting blame).
* The plaintiffs have a vested interest in suing United Airlines, not Republic, because Republic would likely be shielded from paying much if anything due to its current financial standing.
