I have to take a positioning flight out to JFK in mid-August for a flight to JNB. Since my EQMs are a bit light this year, I'm planning DEN-(LAX/SFO)-JFK on PS. Have been watching the NC space like a hawk, with ExpertFlyer alerts set for almost a month now, but nada, nothing, no love. Don't want to book the flight until NC space opens, but I'm getting baffled. I have a 3-day window, Sat/Sun/Mon, any flight. Have looked at the space available, and C is wide open all three days (most flights have <2 assigned seats in C, most showing 0 or 1 assigned). While I know the seat map is a poor indication of actual space, and that PS tends to book late into C, you'd think they'd open one seat on one flight. What's even more baffling is that the return flights (in September no less) have shown some NC space, which I wisely snapped up earlier. United, if you're watching, if you open up NC space now, you'll actually get more revenue out of me, since your PS fares are higher than I expect they will be in another few weeks for these flights. Give me some NC space now, and you'll tempt me not to wait for the lower fares . I do have to ask, though, is this unusual? I've never seen such a dearth of NC space on the PS flights.
