Did a search in the thread, couldn't find anything concrete.
I signed up for SkyMiles and entered my SPG (Plat) number during registration. In my profile I see my SPG number and paperclip icon. Is there anyway to confirm that Platinum perks are active, or do I just wait the 48 hours and assume it's in place?
I had a flight booked on Delta next week and want to know when to attach my new SkyMiles number.
