Use:
www.orbitz.com
www.travelocity.com
and their fare watcher feature
www.iflyswa.com and
subscribe to their click'n'save. often times, ticket prices
will drop to $30 one-way to some cities ie st. louis
to tulsa, little rock, detroit, and
chicago.
works best if you observe ticket prices over a period
of time and select prices at their low, or take
advantage of fare wars when they come out in the news (like
the one that's currently happening right
now)
