Typical travel time from O'Hare International Airport (ORD) to Beijing Daxing International Airport (PKX) in March ranges from roughly 14 to 20+ hours door-to-door depending on connections. Pure airborne time for one-stop itineraries via East Asian hubs is usually 13–15 hours total flight time, with additional layover time at connecting airports like Seoul (ICN), Tokyo (NRT/HND), or Shanghai (PVG). Few, if any, nonstop options operate regularly between ORD and PKX; expect one-stop routings as the norm. Time zone difference: Beijing is UTC+8, Chicago is UTC-6 (UTC-5 during daylight saving time, which may begin in March), so plan for jet lag and check daylight saving changes that can affect schedule timing. Use schedule-focused keywords such as "flight time Chicago to Beijing" and "ORD PKX schedule March" when searching to find optimal connections and departure windows.
