I'm new to CO so not clear about the vagaries of its website. However, in making some recent bookings on UA and CO, and checking to see what my upgrade chances might be on the CO metal flights by checking front cabin seat maps, I am finding F cabins domestically almost always showing only one or two seats open. These are for flights midweek a month or more out. It doesn't seem logical that F could be that fully booked as I can look at UA metal flights on those same days and the front cabins are virtually empty. So does CO fiddle with the display of open seats in its front cabins? Or is it really selling F seats this far out?
