Delta saver award availability to Asia, especially for two or more passengers, can be challenging. Right now though availability for late fall and winter is outstanding on a variety of routes, for the whole family — in some cases 9 or more saver awards.
Specifically flights out of Detroit, Minneapolis, Seattle, Atlanta and Los Angeles are bookable to Tokyo and to China (from Shanghai connecting options on China Eastern are good as well) for November through March.. Notably availability on the Detroit – Beijing, LA – Shanghai, and LA – Tokyo Haneda routes means flying Delta’s business class suites.
