December brings a range of holiday markets, tree lightings, and college sports that affect airport traffic at Richmond International Airport (RIC) and Hartsfield-Jackson Atlanta International Airport (ATL). In Richmond and nearby cities such as Williamsburg and Charlottesville, expect seasonal concerts and holiday parades; in Atlanta, large events like holiday markets, Falcons or Braves games, and concerts can create higher demand for flights and ground transport. If your travel coincides with major events in Atlanta, book flights and ground transfers early and choose flexible tickets when possible. CTA: Check event calendars for Richmond and Atlanta before booking December flights to avoid surprise crowding or fare spikes.
