If you want to go to Asia with the family in business or first class, there’s one airline that’s got you covered and even one best route though there are several good routes.
Star Alliance member Asiana simply offers fantastic award space. The United website is great for seeing this quickly at a glance. Their award calendar will show you which dates have availability — in this case non-stop availability from Los Angeles to Seoul for four passengers. Dates with solid lines have coach award space and dates with dotted lines have premium cabin award space.
