Flight Deals from St. Louis to Hong Kong from $524

St. Louis to Hong Kong is about 7,935 miles. There is no scheduled nonstop service on this route, so the trip requires a connection.

Methodology

Flight times and distances come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.

There are no nonstop flights from St. Louis to Hong Kong. The shortest connecting routing is via Chicago O'Hare on American Airlines to Hong Kong on Cathay Pacific, taking 18 hours 54 minutes total (a 1 hour 33 minute first leg, 1 hour 36 minute layover, and 15 hour 45 minute second leg). Other one-stop options connect through Seattle, Dallas/Fort Worth, San Francisco, or Los Angeles, with the quickest alternatives running around 20 hours 43 minutes.

Methodology

Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours.

From Hong Kong International Airport, the fastest way into the city center is the MTR's Airport Express, which covers the 33 km to Hong Kong Station in 24 minutes with fares around HKD 105–115. Taxis are also widely available; a ride to Kowloon costs roughly HKD 270–300, while Hong Kong Island destinations like Central or Causeway Bay run about HKD 350–400. There are more than 20 Airbus 'A' routes offering comfortable bus service to key areas across Hong Kong Island, Kowloon, and the New Territories. Rideshare via the Uber app connects to licensed local taxis, and private transfers are popular for door-to-door convenience. The Airport Express is the most-used and most efficient public transit option for reaching the city center.

There is no nonstop red-eye from St. Louis to Hong Kong, but a connecting overnight itinerary does operate: Cathay Pacific's red-eye from Dallas-Fort Worth to Hong Kong departs at 22:55 and lands at 05:10 the next morning, after first connecting at DFW from an American Airlines flight with a layover of about 1 hour 46 minutes.

Methodology

Red-eye flights are identified from scheduled local departure and arrival times and block times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes. A flight counts as a red-eye when it departs in the afternoon or evening (3 p.m. or later local time) or in the early hours before 4 a.m., and is in the air at some point between midnight and 4 a.m. local time at both its departure airport and its arrival airport. An evening flight that lands before midnight at its destination is never counted, nor is a morning departure or a daytime long-haul that reaches the next calendar date only because of time zones. Each red-eye is labelled with its timing (for example, overnight and landing the next morning, or late-night and landing after midnight). For connecting itineraries the same rule is applied to the longer leg, from one representative day's flight search.

There is no nonstop service from St. Louis to Hong Kong; the main one-stop routings connect via Chicago O'Hare, Seattle, Dallas/Fort Worth, San Francisco, or Los Angeles. Cathay Pacific operates the long transpacific leg on most of these patterns, typically feeding from American Airlines or Alaska Airlines on the domestic segment, while United Airlines offers a one-stop option through San Francisco entirely on its own metal. The quickest connection is via Chicago with American Airlines and Cathay Pacific at about 18 hours 54 minutes total. Cathay Pacific, American, and Alaska are all oneworld members, while United is Star Alliance.

Methodology

Aircraft types come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.
