Five US carriers including the country’s four largest have applied for coveted slots at Tokyo’s downtown Haneda airport, two months after a landmark agreement was reached between the US and Japan to relax restrictions on flights between the two countries.

Among the carriers seeking slots are: Delta Air Lines, American Airlines, United Airlines, Continental Airlines and Hawaiian Airlines. Delta and United are the two biggest US carriers serving Japan.

Several US airlines currently fly to Narita Airport outside Tokyo, but the close-in Haneda Airport has only recently been opened up to international scheduled flights.
