I think you should check several times a day if you can! Last year I got my low fare down to Orlando at five am or so,(I was up), checked early afternoon and the way down was already up in price. The price for the way back lasted the three days of the sale, it was during the Anniversary sale. Anyway, if I'd only checked the afternoon time, I'd have missed out, so I obsess and check often! Also last year, I unexpectedly got 500 RT for DD23 and friend, to Ft. Lauderdale for a cruise. It had been much more during months of checking, (they were gonna drive), and after I purchased them, the fares went up a few hours later, to 750 and then 900! The kids were happy I was an SW stalker! So, my points are that I think you still have a shot at lower prices, and you need to stalk like crazy as best you can, as well as hope for a bit of luck!
