KIX and BKK aren't as surprising to me as JFK-NRT.
http://news.delta.com/executive-qa-delta-remains-committed-asia-despite-haneda-agreementDelta today announced it will cancel service this fall from New York-JFK to Tokyo-Narita, and from Tokyo-Narita to Osaka and Bangkok, but remains committed to supporting a strong Asia-Pacific network.
The announcement comes a few weeks after the U.S. Department of Transportation tentatively awarded Delta daytime service from Los Angeles and Minneapolis to Tokyo-Haneda. Delta is tentatively slated to receive two of the five available daytime trans-Pacific HND frequencies available for U.S. airlines as part of the new aviation agreement between the U.S. and Japan that limits such access to Tokyos Haneda airport. Tickets for the new route will not be sold until Delta is granted final DOT approval.
