The web site indicates that the new system is up. The status credit fine print no longer indicates that DJ coded connecting flights (with different flight numbers) earn status credits appropriate for a nonstop.
Status Credits accrual is based on single flight segments that consist of individual flight numbers. An itinerary that involves a change in aircraft but retains the same flight number is considered a single flight segment, whereas an itinerary that consists of a change in flight numbers, even if the same aircraft is used for the entire itinerary, will be considered two flight segments.
