Wow! Less than 24 hours to match! Now I'm wondering whether it is worth crediting to TK or UA. I'm probably not going to hit the 50k this year, but will be well over 25k. Since TK requires only 25k to renew Gold (or 37.5k in two years), it may be worth while to funnel some miles over to TK. Although the 50% RDM bonus that I get with UA is still quite nice. Hmm...
