American Airlines, Delta and United Airlines have all applied to serve several US routes from Tokyo Haneda airport after the US and Japan reached a tentative agreement to expand access to the busy airport.

The agreement would open up to 12 additional daytime slot pairs for US carrier operations, according to American Airlines.

American Airlines has proposed flights to Tokyo from Dallas/Fort Worth and Las Vegas starting in 2020. The carrier already operates a daily flight between Los Angeles (LAX) and Haneda but has proposed an additional service leaving LAX at 0040 and arriving at 0445 local time.

The airline says the new flights will be operated as part of an existing Pacific Joint Business agreement with Japan Airlines (JAL) that covers travel among 11 countries in Asia and North America.

Meanwhile, Delta is hoping to launch daily flights from Seattle, Detroit, Atlanta and Portland, Oregon, as well as a twice-daily service from Honolulu, Hawaii. The airline says the move would make it the first US carrier to serve Haneda – a popular airport for business travellers going to Tokyo – from the destinations it has proposed.

These flights would also start in the summer 2020 schedule.

Lastly, United has proposed routes from Newark Liberty International, Chicago O’Hare, Washington Dulles International, Los Angeles, Houston and Guam’s AB Won Pat airports for 2020. The flights would allow US passengers to connect to more than 37 destinations in Japan through United’s joint venture with All Nippon Airways (ANA).

The combined proposals would add competition to any Japanese airlines already serving the US, but all three carriers say the move would increase choice for passengers travelling from major American hubs throughout the country.
