Can staying the weekend get me a cheaper ticket?

Spending the weekend at your destination, like St. Louis, usually means lower airfare since most people fly during this time. Good thing to tell your boss if you have a business trip -- wink-wink.

Why travel during the off-peak season?

Shoulder or off-peak seasons are when most people aren't going to certain locations. So when it is cold, most people head off to warmer climates like the Caribbean, Mexico, Hawaii, etc., just like our feathered friends. But in the summer, you'll find that Europe is where it's at. You may not get the ideal weather, but you'll generally get better rates and avoid the mobs of tourist.
