You are now free to move about the country, because Southwest is offering a 40% discount code for travel from Nov. 28 through Dec. 12, 2012, and Jan. 7 through Feb. 14, 2013. Booking must be completed by 11:59 pm PT on Oct. 11, 2012 with promo code BigDeal40, so book now. Full terms and conditions are available on the promo page. The best thing is that other carriers have seemingly matched the deal. So go to Google's Matrix Airfare Search to see if your desired flights have been matched by any of the other carriers. All U.S. carriers (including Southwest) are required by law to include a free 24-hour cancellation or airfare hold policy for their bookings, so you can always purchase/hold the fare for now and cancel within 24 hours if you change your mind.
