OK Merry, I have checked with CO here in Houston and your letter was actually mailed in 1997, written in "lemon juice" ink and passed through a very warm place before being received by the post in London for expeditious delivery to your home. Obviously, your letter was written before CO decided to "practically" make everyone Platinum with "smoke and mirrors".
Here's how it's done, drop Bronze and "silver plate" all Bronze members, thereby turning their Bronze cards blue. Since Bronze is now blue and Silver is also blue,
something had to be done with Silver, so CO "Gold plated" the blue Silver card. But wait, that enraged the "toters" of real Gold cards. They "ranted, raved, cursed, and sent very nasty e-mails" to CO. CO was in a predicament. They had to do something for the "Toters of Real Gold". So, they decided to replace all those "real" Gold cards with authentic Platinum and allow the "Gold Guys" to present the perception that they were the "Elite of the Elite". Then, CO added this ficticious 90 segment, 75,000 mile,(which no one had to make), qualifier for the very valuable Platinum and told everyone "how great it was going to be". And, "lo and behold", everyone believed it! But, CO discovered that a few "soreheads" were still in existance. So, to eliminate "any" disappointments in its' OnePass Program, and to get everyone to vote for OnePass for the Freddie winner once again, CO sent almost ALL their members an invitation to become the "next" Elite Level by simply paying $150, a modest sum to the "Toter" of an imitation color plastic card. One could even charge the amount to the "Chase Visa" and receive FF miles. What a deal! Everyone immediately took the bait, swallowed the hook, and NOW, all "Million +" in the whole OnePass program is Platinum.
