I've also SDC'd to this exact routing on a MR last year. This time it wasn't an option for me via app, kiosk or website. Not sure if the system is now aware of what routing rules are allowed for a given fare class, or not. I'm sure I could've pushed this with an agent in IAH, but after a mid-con redeye, it wasn't worth the hassle. I was able to SDC to IAH-ORD-LGA via the app, but not what I was hoping for.
