How to Fly Cheaper
To find the cheapest day to fly, go to, select "simple search options," then "see calendar of lowest fares," and enter your destination.

Before you buy a ticket, google "coupon code" and the airline name to see what deals turn up.

Upgrades can cost less than you might think. For example, with a full-fare economy ticket from American Airlines, you can request an upgrade on before you fly for $30 per 500 miles.
