If the new itinerary is showing up on KLM.com - - that is GREAT! It means the seats are HK (holding confirmed). But you WILL want to get the thing finalized.
If you don't want to wait longer for that ticketing link you can try this number that was getting people to Chisholm fairly directly:
1-800-447-3757
(say that your itinerary was originally booked on nwa.com). That way there's always a chance you'll get a savvy Iron Ranger with a heart of gold who can tell you what the real parameters are, and what to realistically expect.
