since WN backdates credit postings when you submit credit for a missing flight, I'm reasonably sure that anyone who adds a missing flight will get an old credit, not points. their system will likely just not be setup to assign any points at all for any flight segment flown before 3/1/11
Right now we see RR credits show up about 4 hours after our flight. any prediction on how fast we'll see points? My thought is that since their website is down consistently for bookings, I don't think anyone will see points the first week or March. They'll show up/post eventually, but it'll be a painful process by some of WN's IT vendors.
