Got matched from PC Platinum RA to Concierge. It's all on how you ask... opened a CC account made the first reservation, then wrote a nice e-mail asking the match to Concierge based on my frequent business traveler profile and dispointment with IHG, sent it with the attached statement from PC RA. Got a reply with approval after 3-4 business days.

This is really nice because IHG just decided to downgrade me to Ambassador (RA status not renewd), their loss…

Good luck
