United and Delta have lowest fares today for travel from Los Angeles LAX to MNL Manila, Philippines $703 to $745 most dates for Monday to Thursday departures from April 7 to May 14. Routes are via Tokyo, Haneda and Nagoya in Japan or United Airlines lets you hopscotch to Honolulu and Guam in both directions. Delta also has routes through Honolulu.
The challenge is to find a long transit layover in Hawaii or Guam. I did not search for potential overnights.
