Not just TODs but Y/B/M-Ups.
Why would any Elite buy an F fare when a Y/B/M fare could be had for less. Unless the F fare has materially fewer restrictions, the Y/B/M fare is exactly the same seat, just for less money.
The minute CO applied this to the UA route network, they eroded quite a bit of F revenue.
