Everyone is given the option of paying in cash or by credit. I paid by credit (and will dispute it).

I'm sure the Panamians are getting their due; the question is what happens to the Trinidad & Tobago "slush fund.". I suspect UA has procedures in place that will catch it before they erroneously send this extra cash to either the Panamanians or Trinis. I suspect UA will just try to quietly pocket the money.
