On Nov. 22 I used nwa.com to do an online checkin for a flight on Nov 23. This is the first time that Mile-zilla points didn't post automatically for the online checkin; I've done this quite a number of times. (Points also posted correctly when I used online checkin for my return flight).

I'm a bit concerned about contacting NW about the missing points because of the 5 point/10 point online checkin question. Any thoughts?
