United Airlines at Tokyo Narita Airport (NRT) — Terminal 1
Tokyo Narita has been United Airlines' primary Asia-Pacific hub since 1986, when the airline acquired Pan American Airways' Pacific division. United operates from Terminal 1 at Narita for both departures and arrivals. Star Alliance partner ANA also operates from Terminal 1, making connections between the two carriers seamless.

United Airlines at Tokyo Haneda Airport (HND) — Terminal 3
Haneda Airport is significantly closer to central Tokyo than Narita and is generally preferred by passengers staying in the city. United operates long-haul US routes from Terminal 3 (the International Terminal). Haneda is accessible via the Keikyu Line or Tokyo Monorail, with journey times of around 15–30 minutes from central Tokyo stations.

Narita vs Haneda — which airport to choose? Haneda is far more convenient for central Tokyo (15–30 min vs 60–90 min), making it the better choice for passengers visiting the city. Narita is preferable if you are connecting from a US city to one of United's Asia-Pacific regional routes (Cebu, Kaohsiung, etc.) or if you are based in Chiba Prefecture. If both airports serve your US destination, check schedules carefully — departure times differ and can affect arrival at your final destination.

Frequently Asked Questions — United Airlines Japan
Can I call United Airlines Japan in Japanese?
Yes. Both the reservations line (03-6732-5011) and the MileagePlus line (03-6732-5022) offer service in Japanese. For passengers calling from within the US who prefer Japanese, United also offers a dedicated Japanese-language line at 1-800-537-3366.
Does United Airlines fly from both Narita and Haneda?
Yes. United operates from both Tokyo airports. Haneda serves primarily long-haul US nonstop routes (Newark, Chicago, Washington, Los Angeles, San Francisco, Guam). Narita serves US nonstop routes plus a growing network of regional Asia-Pacific routes including Cebu, Kaohsiung, Saipan, Koror, and Ulaanbaatar. Some US destinations (like Newark and Los Angeles) are served from both airports, offering passengers a choice of departure times and airport convenience.
What happens during the New Year holiday (年末年始)?
During the nenmatsu-nenshi period from December 30 to January 3, the reservations line operates on reduced hours (9:00 a.m. to 5:00 p.m. instead of the usual 6:00 p.m. closing). The MileagePlus Service Centre is closed entirely during this period. Flights operate normally throughout the holiday period, and the United website and app remain fully functional for self-service bookings and changes.
Can I earn ANA miles on United Airlines flights?
Yes. United Airlines and ANA (All Nippon Airways) are both members of the Star Alliance, and have a close bilateral partnership. You can credit United flights to your ANA Mileage Club account (and vice versa). The mileage earning rate depends on your fare class. You can also use ANA miles to book award flights on United, and use United MileagePlus miles to book award flights on ANA — both through the respective loyalty programme's website or by calling the relevant service centre.
Does United have a lounge at Narita Airport?
Yes. United operates a United Club lounge in Terminal 1 at Narita. Access is available to Polaris business class passengers, United Club members, and Star Alliance Gold status holders. In addition, eligible passengers can use the ANA Lounge in the same terminal. At Haneda Terminal 3, there is no dedicated United lounge, but ANA Lounge access is available to qualifying passengers.
How early should I arrive at Narita or Haneda for a United Airlines flight?
United recommends arriving at least 3 hours before departure for international flights. This is especially important at Narita, where immigration and security queues can be lengthy during peak hours. At Haneda, the process tends to be somewhat quicker, but 2.5–3 hours is still advisable for US-bound flights, which require additional security screening.
Can I book United flights on the Japanese-language website?
Yes. The full Japanese-language version of the United website is available at united.com/ja/jp. You can search, book, manage reservations, check in online, and access your MileagePlus account entirely in Japanese. Fares can be displayed in Japanese yen (JPY).
