They told me that they were adding up the total year to date mileage from my TWA with my American, so even though I didn't fly AA much I should get Platinum because of all the TWA miles.

So at least I'll get a 100% mileage bonus, which will offset TWA's very generous minimum miles. I will miss the stickerless upgrades of TWA, but maybe AA will have a twinge of generocity at the end of the year and put a few upgrades in my account for Christmas.

I'll miss TWA, but at least the miles are not disappearing, much like my Pan Am miles that became Delta miles, and my Eastern miles that became Continental.

In a few more years there will probably be only two or three major airlines plus a bunch of regional airlines that partner with one another.
