$499 or 49,900 miles for the studio on UA 1 for my booked flight. I was going to burn some miles, even at the bad rate, but it won't let me on the app. It will only take the $$.Works fine on the website for me though.

interesting that the price is the same for all 8 studios, even though 2 of them don't allow companion seating (not that I'm going to have a companion, nor do I have interest in a middle seat)
