This may be a dumb question but my wife and I was wondering if you could buy airline tickets a year out from your departure date? We want to fly out of Jackson, MS to Orlando on Southwest Airlines. We are planning a trip next May 2012. Is it true that air tickets are cheaper the further in advance you buy them? We usually drive but this time we want to fly with our kids to Orlando and are trying to get the best deal possible. Thanks so much...
