They all have limited inventory available for points, but I pretty much agree. I can usually get Economy Comfort, though.
United has two levels of miles redemption. Full rate for use any seat anytime and half rate on certain itineraries if you book well in advance. If you have the miles you can always book a seat on United. The key is trying to find the cheaper mileage seats.
