I think this isn't a bad idea. But...this idea is trying to remedy the symptom rather than the cause. It effectively would make us police the rules CO makes.

The real issue that we need to tackle is two-fold. One, I believe COs upgrade rules are too conveluted. Two, CO has engineered the system so it can be and is gamed frequently by agents and therefore by some passengers.

If CO implemented an upgrade policy and implementation similar to AA for example, I think the complaints would go away virtually overnight.

Even if CO kept a more conveluted system like DL, UA, or its own, it could tighten the system so agents can't abuse it. If pax get confidence that CO is honoring the published upgrade rules, then fewer complaints should arise.

My 2 cents from the peanut gallery.
