For December travel from Hartsfield-Jackson Atlanta International Airport (ATL) to London Heathrow Airport (LHR), the best combination of price and convenience is often early December (first two weeks) or mid-week departures (Tuesday–Thursday). Avoid the peak holiday travel window (about 3–7 days before Christmas through the New Year) when fares and airport crowds spike.

Direct (nonstop) flights from Hartsfield-Jackson Atlanta International Airport (ATL) to London Heathrow Airport (LHR) save time (about 8+ hours) and reduce the risk of missed connections — a major advantage during busy December travel.
