Its funny, i read that same article posted about the day and times. On a Southwest flight I was looking at around 3PM on a Tuesday, the price actually went UP! It only went up about $40 but then was out of my points range. So i waited until the next week and bought them when they were low again(on a monday)My suggestion, if you have time, don't trust any article. Use something like that asa reference and then watch prices yourself for a week or two until you find one that fits your needs/budget.
