Business travelers would flock to UA under such a scenario.
At the expense of P (and Z) fares and TOD that they can sell.
I'm not sure I want a flock of el-cheapos heading toward my business for the freebies. What happens to them when I have to cut them off? Take a look at the Mariott RewardsPlus status reduction / lounge access removal for a hint.
