Route guide
Best Business Class from the USA to Asia
36 tracked routes · 8 departure cities · 19 airlines
CabinScore tracks 36 routes from the USA to Asia, flown by 19 airlines. The best business cabin CabinScore has measured on any of them rates 9.5/10; on the weakest route the best you can do is 5.9/10. That gap is the whole reason to check before booking — the same fare buys very different seats depending on which city you leave from.
This covers the routes CabinScore tracks between the USA and Asia — not every route flown, and only the cabins it has measured. Scores come from seat metrics; the odds of actually getting a given cabin come from the tracked flight history on each route's own page.

The highest-scoring business cabins CabinScore has measured on the USA–Asia routes. Which of them you can book depends on your departure city — the route list below is the honest version of that.

How This Ranking Is Built
CabinScore ranks each route by the highest-scoring business cabin it has measured on that route. Scores come from seat metrics — width, bed length, recline, direct aisle access, privacy, and cabin density — not from reviews. Full methodology.
A high score is what the best cabin on the route is worth, not a promise you will get it. Most carriers are mid-retrofit, so two aircraft on the same route the same week can be a generation apart; each route page shows the observed equipment mix, which is the number that decides your seat.
Coverage is partial in both directions: CabinScore tracks 36 routes between the USA and Asia, and scores a subset of the cabins flying them. A route or airline missing here is a gap in the data, not a judgement.
