A few years ago I had a job that had me flying 5000 miles a week. I signed up for AA's status challenge and qualified for platinum status in nearly a month.<p>I think they charge for taking the challenge now (it was free then) but it's well worth it. Not only do you get better seats, free bag checking, priority security access, and earn upgrades, but that was 30,000+ additional bonus miles I wouldn't have earned had I just skipped the challenge and qualified for the status the normal way.<p>Also, if you're on the fringe between status tiers, often times it's very much worth it to spend a couple hundred bucks on a "mileage run" if it means the extra EQM will put you into top-tier status.
