For somebody that travels the same route over and over again, what are some ways to save on airfare?
I remember when humorist Dave Barry discussed some guy who invented the software that guaranteed that no two airline passengers ever paid the same fare.  As with much of Dave Barry's stuff, it has way too much truth in it. Research when the best time frame to buy your tickets is.  It varies wildly with time of day, time of week, time of year, whether the plane is half-empty or not, which airline you're traveling on, etc. Beyond that, if you can rack up frequent flier miles fast enough, you maybe can offset the cost of one of those trips.
