I didn't think this was a bad thing as it doesn't add any more elites, just makes it easier to re-qualify. So same number of elites next year unless I'm missing something. If they keep this promo up though I would certainly fly a little less. Spending 30K a year on a CC is pretty easy.
To me, a bigger issue is the preium credit cards that give all the benefits of 50K status. Now anyone who has those credit cards has the same benefits as a million miler. I spent 20 years becoming a million miler when I could've got the same benefits from the credit card I now hold.
