I travel for leisure, 4-6 times a year. I'm racking up my Mileage Points from CC sign ups and have am Silver with Delta this year thanks to a transfer bonus.

My question is, when do MR costs become equal to the reward of Silver or better. Is it a waste of my time and money to shoot for status? I have been contemplating the flight from BNA to JNB for 6cpm to keep my silver status for another year. Then I starting thinkin with very few domestic flights each year, is it really worth it?

Anyone out there a in-frequent flyer and spend money just to maintain status?
