I think they all are the same. Take advantage when things are good and beg when things are bad. My wife and I have been 1K for last 6 years and would be willing to try AA if we did receive similar bennies. We usually travel M/H and upgrade (90% intl- 99% upgrade with SWU), sometimes (like tomorrow) Around the World in Business (upgraded to 1st on UA). Usually end up with 125-160K per year.
