Major carriers serving the Chicago (All Airports) (CHIA) to Hong Kong International Airport (HKG) corridor in November include both U.S. legacy airlines and Asian international carriers. U.S. carriers may offer direct or West Coast-connected services with robust frequent-flyer options, while Asian carriers provide smooth onward connectivity through hubs like Taipei (TPE), Seoul (ICN), and Shanghai (PVG). In economy, look for competitive pricing and occasional promotional November sales; for business class, compare seat comfort, lounge access, and convenient departure times from O'Hare (ORD). Use airline comparison tools to evaluate baggage allowances, change policies, and total travel time before booking your Chicago to Hong Kong flight in November.
