The problem is TRANSPARENCY!!! I honestly believe that UA does not give us honest, consistent answers because they are as much in the dark as we are. Everyone knows how it's "supposed" to work but no one knows why it doesn't. I don't really think UA is lyeing or playing games as much as they just don't think it's that important to fix
I fly a lot of Full fare flights but not on UA. I Have no reason to as long as they give me upgrades & they work. I've also been lucky w a 100% success rate but another customer, same status as me w similar travel habits has a 50% success rate which is what makes no sense.
