Anyone here use credit cards specifically to earn airline miles to travel with? Or just any travel rewards credit cards, maybe for hotels or even car rentals? I have a small handful of regular credit cards that still earn points and cash back, but thought it might be smart to also get a travel rewards card and start earning points toward my next flight outta here, whenever that will be.
I know some of these cards you have to pay for annually, so that's why I haven't got one yet. Plus you have to worry about flight restrictions, black outs and transferring points between programs... are they worth it or just a gimmick?
