I'll be evaluating my options between now and January. However, as I live only a few miles from IAH, there may not be any good options. I guess I could use AF/KL/LH for my TATL needs and credit to either OK, AC, or BD for top-tier in *A or SkyTeam on the cheap.

The only viable alternative domestic option for a Houston-based person is WN. I'll have to evaluate my EUA percentage at the end of the year and consider whether it would be better to spend all my flights in a decent Y seat with no shot of an upgrade, or stick with CO for some shot of an upgrade. However, if CO begins seriously degrading its F product (Sundae/Menu/etc. cuts don't bode well), I'll just switch to WN. Way to go, Larry Lorenzo.
