Part Two of Holiday Traveling ...
Johnny says he can't underscore enough the importance of being flexible. If you're checking bags, Southwest Airlines is the way to go. They allow two free checked bags.
Also, keep in mind the time of day. If you leave early in the morning, you can save a lot.
Alternate Airports will also save you a lot.
Use Search Tools. Johnny Jet has a really cool one.
Once you've booked a flight, keep looking. You can always cancel your other flight if it's within a day or two. Takes effort, but it's worth saving for.
Using miles ... they make it hard during the holidays. But using your credit card POINTS may be a better option.
Use a travel agent. If you can find a good one, they can work wonders.

Hidden Cities. Check out SkipLagged.com. Airlines don't like flyers using hidden cities - they'll even take away your miles for doing it, but they'll save you a lot.
