Nonstop flights to Hong Kong from US cities

Airlines are as of recent schedules (November 2026) and change by season; check with the airline. Times are westbound and approximate; flights back to the US are usually 1 to 2 hours shorter.

Airlines flying to Hong Kong from the US

Cathay Pacific, Hong Kong's home airline, flies nonstop from seven US cities: Boston, New York JFK, Chicago, Dallas/Fort Worth, Seattle, San Francisco and Los Angeles, as of recent schedules (November 2026). United flies from San Francisco, Los Angeles and Newark, and Delta began a daily Los Angeles flight on 6 June 2026, its first Hong Kong service in years.

Cathay Pacific is a oneworld member and partners with American, so many one-stop trips connect on American to a Cathay gateway on one ticket. United connects its own network to its Pacific flights, and Delta connects through Los Angeles or through Seoul with Korean Air.

Best time to visit Hong Kong

October to December is the most comfortable season, with lower humidity, clearer skies for the harbor views and good hiking weather. January to March is cool and often grey, and Chinese New Year, usually in late January or February, brings the city's biggest celebrations and very busy travel days.

From May to September Hong Kong is hot and humid, with heavy showers. The Hong Kong Observatory notes that tropical cyclones can affect the city from about May to November, most often from July to September. When a high typhoon signal is raised, flights, ferries and some public transport can stop at short notice, so a flexible ticket helps in those months.

Hong Kong International Airport

The airport sits on Chek Lap Kok, an island off Lantau, about 20 miles west of Central. Flights arrive at Terminal 1. Since May 2026 a number of airlines have moved check-in to the new Terminal 2 departure building, while boarding stays at Terminal 1 gates, so check where your airline checks in on the way home.

Many Cathay Pacific passengers connect at Hong Kong to cities across Asia and Australia. Transfers stay airside, and the airport also has ferry links to some cities in the Greater Bay Area for travelers continuing into mainland China.

Entry rules for US citizens

US citizens can visit Hong Kong without a visa for up to 90 days. Your passport should be valid for your whole stay, and you may be asked for proof of onward travel; check the Hong Kong Immigration Department for current passport rules. Hong Kong keeps its own immigration rules, separate from mainland China.

If you plan to cross into mainland China, you need to meet mainland China's entry rules, which are different. Check the current requirements before you go, and read the State Department's travel advisory for Hong Kong on travel.state.gov.

Getting from the airport into the city

The Airport Express is the fastest way into town: about 20 to 22 minutes to Kowloon and about 24 minutes to Hong Kong station in Central, with trains every few minutes for most of the day. Airport buses run to most districts and are slower but serve more hotels directly.

Taxis are color-coded by area. Red taxis serve most of Hong Kong Island and Kowloon, green taxis the New Territories and blue taxis Lantau, so join the right queue outside arrivals.

Time difference and the date line

Hong Kong is on UTC+8 all year. That puts it 13 hours ahead of New York in the US winter and 12 hours ahead in summer, and 16 or 15 hours ahead of Los Angeles.

Most flights from the US leave late at night or around midday and cross the International Date Line, arriving in Hong Kong one or two calendar days later. Flights back arrive in the US on the same calendar date or earlier.
