RC is one that has had it. Just tried checking for my RC card - RC no longer has it as of 1/15/20.
When I go to the site, This message pops up:
“ Effective 1/15/20, your Ritz Carlton Visa Infinite card no longer offers the Visa Discount Air Benefit. Air itineraries booked via the Visa Discount Air Benefit prior to 1/15/20 will still be honored and valid for travel. For full Terms & Conditions and FAQs please visit www.visa.com/discountair. If you need servicing on your existing Visa Discount Air itinerary, please contact the airlines directly for assistance as Concierge will no longer have access to your itinerary. Thank you”
