I did it a few years ago, had an AMEX Gold and Platinum Edge and added the Explorer. However it wasn't recent, I did it in 2018.I currently hold the Explorer card, opened recently for the bonus signup points. I held it back in 2016 when it was first released.
I wish to get into the Ascent program to maximise my points transfer to KRIS. Does anyone know/has anyone recently opened another AMEX card (I think it was the Platinum Edge?) card to the migrate their account and points into the Ascent program? Any advice?
