I've got almost 2M miles that I can't optimize. Upgrades are, well, byzantine since the UA-CO merger. Booking engines are notoriously inferior to checking segments on one's own. And, I don't comprehend SABRE and fare-code-peak. Any tools that I could use would be greatly appreciated. Let vendors submit. Users can decide whether to ignore or use. At least we'd know where to look for them. More speech is better than less.
