Flying RDU-DEN this weekend and was booked into a W fare. With it being operated by an A319, and there only being three seats left, I decided to look at the various upgrade options. UA.bomb offered me a $192 fee to move into F which I felt was reasonable for a four hour flight. Additionally, it immediately reissued the ticket into P class, so the combination of a dinner, free alcohol, wider seat and more EQMs seemed worth the price.
