Why panic at all... Your A3 Gold is still valid until November 2015. If you want maximum validity, you should not attempt matching anything until October 2015. The minute you match, the clock starts counting down for the new program's requalification.
TK is not the answer. You STILL HAVE TO requalify over at TK, 25,000 miles in one year or 37,500 miles in 2 years. With the latest (massive) devaluation at TK, most economy tickets earn only 25% to 50% of mileage, and that's for TK's own flights. Other airlines, a lot of fare classes don't earn anything at all.
