Some changes in the last day...
The flight status problem I noted appears to be fixed. (All segments on multi-segment flight now showing.)
The "Trip Details" link on the itineraries is gone. I hope that comes back and is properly implemented (at least giving us what we have on nwa.com). What's left is a link to the flight details (equipment type, etc) of the first flight in the itinerary. Not the most useful info.
