Pricing on Charlotte to Chania business class swings widely depending on how far out you book and which connecting hub the itinerary uses. The lower end of that $2,500–$6,200 range typically shows up 3-4 months out during January, February, and March, when transatlantic demand to Greece is soft and airlines release more premium inventory into consolidator channels. Booking inside 6 weeks of travel, especially for July or August departures, almost always pushes into the upper range or beyond it. October and November also see good value, since Crete's shoulder season keeps leisure demand down while business and long-stay travel keeps flights running. If your dates are flexible, shifting a trip by even two weeks around Easter or the August peak can mean a four-figure difference in fare.
