Air Mileage Runs
Some frequent flyers will strive for elite-level airline qualification by taking a "mileage run" to
rack up additional miles to get the perks of premium levels. They look for a cheap, long trip for a mileage run. One wasted day may yield more comfort for travels all year. The key is to maximize distance and minimize cost.
www.FlyerTalk.com is a forum for road warriors, where they share ideas and post good fares that make for productive mileage runs.
www.MilesMaven.com is another source of bonus mile promotions, a site that lists promotions and will tell you what you can find on specific routes. It lists promotions on a particular airline if you want to hunt for a productive mileage run and can also show you hotel promotions that can generate more miles or points.
