How do you guys find out about the cheap airfare rates? I always see posts that Delta is having a sale, but I don't know how you find out about these sales. I am traveling to Minneapolis from either Baton Rouge or New Orleans on 7/25 to 7/28 and was looking for a cheap rate. Today is fourteen days before my travel date and I am finding the same rate that I got last month only 3 days before my travel date. Any suggestions?
