Delta Air Lines (DL, Atlanta Hartsfield Jackson) has requested permission to move its daily A330-200 service between Detroit Metropolitan and Tokyo Haneda to Seattle Tacoma Int'l arguing that demand for flights to Haneda airport would have been much higher from the US West Coast than from the Eastern US. The number of international flights allowed to operate to Haneda is still heavily restricted and Delta was one of the carriers receiving traffic rights for two daily flights from the US to Haneda. It currently serves the airport daily from Detroit and Los Angeles. It also serves its Tokyo Narita hub daily from Detroit, LA and Seattle as well as many other US cities.
