When I flew NWA previously, as I moved from Silver to Gold or Gold to Platinum I would have to contact them to update any future flights I had booked with the new status otherwise, the ticket would only recognize my status as what it was at the time of booking. I'm about to move from Silver to Gold with Delta and I'm wondering if the same situation exists with them? I fly weekly and usually have 5-6 flights booked out into the future.

Thanks!
