Decision Making Softwares

Gullnet and Southwest Airlines' early ticket prices help me decide the best time to fly down to Florida. I purchase tickets online from Southwest Airlines to fly to Florida about three times a year.  I like to buy my tickets early so I can get them at a cheaper price. To do this, I go on Gullnet in the summer and check my classes I enrolled in for the fall semester. After I see what time my last class of the week ends, I look at all the flight times online and purchase the tickets that will fit my schedule the best.
