Well, the fare has been up here for 3 weeks and on CO.com for at least a couple. So, yes I had luck with ticketing it, but that was on Nov 17. And yes, there are still seats availabile in L for $99 OW--you just have to look a bit, but you probably will be paying 199 for the other leg--still not a bad deal at under 400 all in.
here is more info in the MR threads:
