Transpacific award availability on Star Alliance can be tricky at times- there are some tried and tested routes such as Haneda to Los Angeles and Seoul to San Francisco with good availability, but here’s another good option starting mid-next year. Air China generally have very good award space and their Boeing 777-300ER product is one of the best transatlantic featuring fully flat seats in business class, while ANA has angled lie flat seats on their Haneda to LA route, and United’s seats are 8-abreast in business class. Look out for this great redemption option set to hit our Star Alliance skies shortly.
