But other similar airports have UCs. that is not a valid metric, those are sunken costs. A new CLT UC would require new capital costs and then ongoing operating expenses? What new money would fund it?

CLT is an O/D airport. Arriving passengers don't use UC so it would be based on departing passenger. What is departure profile look like? What hours of operations be needed?

Does the space even exist?

Would the AA dominated airport support a UA UC?
