I've been hoarding on Capital One. I charge everything I can on my double miles card and I have gotten the fee waived several times. I'm hoping to learn some new tricks here to increase venues, etc. but, right now, I'm saving for a big flight. I get nervous when my sky miles balance goes to zero! Last year I flew to Honduras, California, New Mexico, and Florida on four separate trips from EWR with United miles. I paid a total of $180 for all four flights and got upgraded to first class on one of them. It makes me happy!
