A few of my thoughts are . . .
1) I'm glad to hear an occasional good thought, too! I'm fairly happy with Delta. Every now n then, something totally stupid happens, that prompts a call, but in general, I feel like I'm treated ok as a "T class" Platinum - hopefully Diamond this year, due to rollover.
2) I don't know the first thing about status matching, but, couldn't you have attempted a status match rather than doing it the hard way?
3) Does CO fly to THAT many TX cities that you need to fly to that DL doesn't?
4) I expect a few PM's and lower who will thank you for giving them your F seats!
