I just moved and will be commuting every three weeks between RDU and Bermuda. I will often take extra segments on my flights, get a 500-mile minimum even for some 120-mile flights, and will get a 50% bonus on my flight miles as a gold elite.

For all that flying, I expect to get barely more miles from the flying than I will from a single credit card signup bonus for a card my wife just was approved for.

Just a little thought for those who are trying to think about how to run up big mileage balances - it's not from flying!
