Get Outta Dodge For Less

How far in advance do you have to book to get the best airfare? According to new research by CheapAir.com based on the travel site's review of 560 million airfares, the optimal time to book a domestic flight is 49 days in advance. If you're flying overseas, you should book almost three months -- 81 days, to be precise -- before you travel.

While the average domestic flight was the cheapest 49 days out, it didn't start to rise dramatically in price until about two weeks before the departure date. But if you wait until the day or two before you want to travel, get ready for some serious pocketbook pain.

**FYI: Other factoids of note: Booking a flight on a Tuesday or Wednesday is not likely to save any money. But flying on a Tuesday or Wednesday will.

Good to know.
