I have flown this route in free ps F a dozen times in the past 2 years. This used to be an incredibly easy route to find multiple XF seats, even on busy Thurs/Fri pm flights. About 6 weeks ago, UA pulled almost all XF inventory. There is sometimes 1 XF seat on the early AM flight, but that's it. I guess UA got sick of bmi customers traveling for dirt cheap on this route with ease.
