And this is what makes Flyertalk great! This worked perfectly and I had no idea this tool existed at all. I got it for $547 which I'm pretty happy with given the cost to get to ELH just in economy (plus bag fees). I imagine it might have been the $512 rate had I canceled my previous reservation first but I'm not going to split hairs over $100.
There's also bookwithmatrix.com
Yeah, matrix is wonderful if you want something weird or particular (specific flights or minconnect 8:00 to explore a gateway layover city before intl flight)
