Sometimes when reservation requests by deep discount travelers are refused, demanders take their business elsewhere; they “balk.” At other times, such demanders negotiate and can be “sold up” to higher fare service like United’s Economy

fewer seats (or more) for late-arriving full-fare passengers?
