Perhaps this is a silly question but I am looking for advice on how to find cheap airfares. I will be going to Texas the first week of August and don't really have any experience on hunting down cheap airfares. Hubby and I have kept all of our vacations in-state since we married so this will be my first experience with this. Any Advice? What sites are good for cheap airfares? Any particular airline? What sort of things should I look for? Thanks!
