I am trying to book tickets from EWR to LAS and use Miles for upgrades. I have checked many dates and there is nothing available. I then decided to try booking BF seats to see what was going on and lo and behold MANY flights w/NO BF SEATS SOLD but still no upgrades. Does that mean that there are many flights w/NO UPGRADE SEATS AT ALL?!?!?!?!? Isn;t this outrageous? What is going on? Does NO ONE CARE?
