And, E, as I see it on ITN and other search tools, is not published. But P is a good barometer for now, I suppose.
Either way, I see F8 on an A319 with 12 F seats. For all I know all 12 could be for sale. In many random date checks, I can never seem to find P inventory, despite F8 showing, on any PHL-LAS flight.
