I am Silver Preferred and within 2 days of my flight on Sunday from PHL-DFW. I received notification that there were no upgrades available, but US Air is still selling first class tickets on their website. I haven't had this happen before and always am upgraded if the seat was available and after it always showed Sold Out for first class.
I called the Preferred desk and they said the seat is available, but not released.
Does anyone know what is going on? Is there a way to get this upgrade? Any experience if this seat will get released or when I should watch for it so I get it?
Any information or tips on how I can ensure this seat is appreciated.
