I successfully book these fares DCA>FLL on occasion. I believe these are offered in markets where DL needs to compete with low budget carriers (Jet Blue, Spirit, Airtran) that also offer a "premium" product. I have NEVER booked one via delta.dumb (com). I find the easiest way is to figure out if the fares are in the system (KVS or expert flyer) and then call the elite line and find someone that knows how to book them--this can be a challenge. Many agents don't even know what a Q-up is. I flew on one of these fares last weekend and actual inventory was A and I, so discounted first/business. I don't think searching for P or J inventory will help--I think you need both Q and A or I to be available at the time of booking, and of course the fare must be valid for the time and place you want to travel.
