So Mrs. WNK and I are wanting to travel to Australia around Sept. 2014. We have a few CC's (Southwest being the one with points) and are looking to sign up for a few more to really start taking advantage of flyer miles and other rewards. We were thinking Discover card (random rewards) and British Airways (Avios rewards) but want your expert opinions. Looks like if I signed up for BA now, I will only get 50k Avios (which is a one-way to Brisbane for one person). Need some help here from the CC experts on best ones to sign up for at this point in time. Mrs. WNK just graduated from Law School back in May so we are now a two income family (DINKs - Dual Income No Kids) and we want to have a little fun before WNK Jr's start popping out. We have great credit status and are home owners (not sure if relevant but maybe?). I'd love to learn to be a card churner.
