This is a very upsetting development. It was my main source of information for deciding which flight to book, and there was NO CONFUSION on my part. This is a true game changer in my loyalty to UA, especially in light of the tendency to sell every F seat, regardless of the price, instead of upgrading a loyal member. This reflects poorly on the culture of UA, as pertaining to transparency. With the new policy of CPU's being applied with no seat assignment, one will really have no way to tell how many F seats are available. I'm hoping that UA will do the right thing and reverse itself on this one.
