Here’s one of those obvious stories. Travel deals for the holidays are starting to disappear. Here’s one news station that wants to remind you that the laws of economics, despite the bad economy, are still working. Supply, demand and price people are willing to pay to go home for Christmas.

Sure, there will always be a few last minute deals, but those are offers that come when a business sees a particular package has not garnered the response businesses were hoping for.

But if you need a specific flight on a specific day, airlines know they have you: And you’re going to pay. The key to booking a cheap ticket — book early or expect to pay top dollar. It’s the way of the plane.

Additionally, the consolidation of airlines has created one airline cities in many regions. This certainly cuts back on your choices — and your potential discounts.

Still trying to save money? Fly on Thursday, return on Monday. That extra flexibility can save you a lot of cash — and if you’re heading home, think about flying on Saturday? That will give you a chance to hang out with friends one more night and then board a plane Saturday afternoon (you may not want an early morning flight, as a hangover never makes for a fun day at the airport.)

The key to booking flights for holidays is to remember this: If you can see Christmas decorations at the store, you’re too late.
