We have flown with Delta and SW for many years. SW has always had the best prices for us. We usually book a couple of months in advance. You will see prices creep up one day, down the next. It is just the way it goes. Fortunately with SW, you can rebook at at lower rate and receive a credit should your fare decrease. In my opinion, waiting too long can be risky. You will be at their mercy as far as flight times, days go. Booking earlier allows you to book on your terms, but you always run the risk of a better price coming along. It's a gamble... Good Luck!!
