For December travel from San Francisco International Airport (SFO) to Hong Kong International Airport (HKG), arrive at least 3 hours before your scheduled departure to allow time for check-in, security screening, and holiday crowds.

The best time to fly SFO to HKG in December is early month midweek (Tues–Thurs) when demand and fares are typically lower. Book at least 6–10 weeks ahead to secure reasonable prices—late November is a good window to lock in fares before December surges. Avoid traveling the week of Christmas and New Year's Eve unless necessary, as prices and crowds peak then.

Nonstop flights between San Francisco International Airport (SFO) and Hong Kong International Airport (HKG) are fastest—typically 14–15 hours—but often cost more during December peak travel. Connecting flights via Tokyo (NRT/HND), Taipei (TPE), or Seoul (ICN) can be significantly cheaper and provide daytime travel options, though they add layover time and potential for missed connections in busy December travel windows. If you prioritize comfort and minimizing disruptions, choose nonstop service; if cost-savings or loyalty program credits are more important, consider one-stop itineraries with 2–4 hour minimum connections.

One-stop alternatives such as ANA (via Tokyo), EVA Air (via Taipei), and Korean Air (via Seoul) can offer better off-peak pricing or frequent flyer opportunities but add journey time.

Nonstop flights from San Francisco International Airport (SFO) to Hong Kong International Airport (HKG) typically take about 14 to 15 hours westbound in December, depending on winds and routing. Major carriers offering nonstop services include Cathay Pacific and United Airlines; flight departures are often late afternoon or evening from SFO with arrivals in Hong Kong the following afternoon or evening local time due to time zone differences. Connecting itineraries via Tokyo (NRT/HND), Taipei (TPE), Seoul (ICN) or Vancouver (YVR) may add 3–8 hours of travel time but can offer daytime departures or lower fares.

To find cheap SFO to HKG December flights, start monitoring fares 8–12 weeks before departure and set fare alerts across Google Flights, Skyscanner, and airline websites.

Be open to one-stop routes via Tokyo (NRT/HND), Taipei (TPE), or Seoul (ICN) to save money—often these routes have competitive pricing. Use flexible date search tools, bundle with hotel packages, and join airline newsletters for flash sales. When comparing fares, account for baggage fees and seat selection costs to calculate true savings.
